Tech Culture: Staying safe online

31:13 /

From spyware to computer viruses, there is a lot of malicious software out there that can harm your computer and put your private data in jeopardy. CNET's Dong Ngo and Brian Tong will fill you in on the best practices and software to keep you safe online.

[ music ] ^M00:00:07 >> What's up? Good afternoon. Welcome to Editor's Office Hours. I am Brian Tong. I'm here with, what was your name again? >> Dom Ngo. >> Oh, okay, there we go. I didn't remember it because you haven't been on here before. So you guys, thanks for coming out. Dom's in the house. We're gonna be talking about today, about web safety and security. >> Yeah, exactly. >> Basically, on all things, computer safety and security? Okay, so talk ranging from etiquette, applications that you guys might be interested, and hopefully we can help you with that. And also tips of what you guys need to be aware of cause you know, things constantly keep changing. But there are some kind of fundamental common sense things. Now right now on our end, it looks like the chat may or may not be working for you down below us, so bear with us. But you can still ask us questions up here in the right hand corner box. That's what we need to keep this show pumping. The past few days you guys have been sending us tons of awesome questions. So if you need to get set up, user name, password, and an email address will allow you to send us questions directly, and that's how we'll be able to take care of you. So we're gonna get things started off with web safety. Obviously, there is quite a large range of ways to be safe. I guess in general when you start off, how do you, what do you recommend people do to first of all be safe? Let's talk about just our computer now. What do you recommend them to do to just be safe initially? >> To be safe initially, I think okay, one of things about being safe online, which started with being safe offline that your biggest foe, or biggest adversary is you. It's true. >> You are your biggest adversary. >> You are your biggest adversary, and it means that you need to be aware of what you're doing, and who you're doing with, and you know exactly what you're doing, and whether or not the person you are in contact with is the person you think he or she is. So that's the bad news that you are your biggest foe. The good news is that because you are the biggest foe, you can do something about it. I mean it's easier to do something about you than about others. I can't do a thing about him here, right? >> You touched me. I'm so touched. I'm just kidding. >> So what I'm saying is, you just be aware of what you're doing, and don't try doing stuff that you are, you say I'm not so sure of. And don't get too caught up in what you're doing and forget about the fact that this is virtual and this is online. This is not real. >> Well it sounds like you were just talking about real life, but you know, that's, like you said, etiquette, know who you're hanging out with and who you're dealing with overlaps from the real world to the virtual world. >> Oh the truth of the matter is that, you know, when you go chatting somebody online or receive an email, okay, I receive an email from Brian Tong, for example. But it might not be, it might not be that Brian who actually wrote the email. Somebody else pretended to be Brian. Or if you're even chatting with somebody, you're in real time, you don't see the person's, you know, face. You don't know whether that person is the person that you are talking with. >> Mm-hmm. >> And if you just, because you know, the person your friends' account can get compromised. And then another bad guy who'd come and pretend to be him or her, and they're asking for your, for the you know, credit card number for example, or your other account information. I have a friend who actually got their email hacked, and then a lot of her friends you know, got their email hacked too because they believed that the person who got, you know, the main hack in the first place was a real person. >> Mm-hmm, mm-hmm. >> And, so just be careful. Be, make sure that you know, you keep in check. You know, the person you talk to online is a real person, or the person that you know. >> Excellent. Okay, so maybe we'll answer a few questions, and then we'll jump back into some other things. I'm gonna take this first question from CafeMacchiato [assumed spelling]. What's up, Cafe? The question is - >> Cafe, I like Cafe. >> You like Cafe? >> Yeah, caffeine. >> Cafe eine, okay. The question is, hi guys, there are lots of anti-virus probably software out there for Windows and much less for Mac as it appears. Is it a common practice for, to run Mac OS ten without any anti-virus and anti-spyware installed? So I would say as a Mac user, I know you don't care right now. >> But I thought that people moved to Mac because they don't need to use anything, are cool about security. >> I think you do need a, ultimately, like you said, you're your worst enemy, right? >> That's true. >> So you do need to be aware, don't send me any viruses or anything, but I used to have their anti-virus software on my machine, but it would just take so long to run, and it was kind of annoying and I never got a virus that I basically got rid of it. Spyware, I think you know, even from the first place, with spyware on so many computers, it's up to you to just not open up and click on things that you're not aware of, or just don't make sense to you just for the hell of it, right? I mean, that's a lot of ways how, you know, I think most people get their spyware. Like what do you have to say, at least on the PC side, on a scale of one to ten? >> Mm-hmm. >> How important do you think it is for PC users to have anti-virus and anti-spyware? I think it's important for both. >> I would say eleven. >> Really. >> Yes. And really not because I hate PC, but I think because PC is so popular. >> Yeah. >> It is the target all kinds of, most of, all kinds of you know, online, you know, virus or like a scam. >> Yeah. >> So it's very important, you know, it's very important that you have some sort of anti-virus and anti-spyware on your Windows machine. And be aware of yourself. >> Yeah. >> On top of that. >> And also I said a scale of one to ten, not eleven. That doesn't exist on the scale. >> I go up to eleven. [ laughter ] >> That's your own scale? >> That's my scale. Is very important, yeah. >> Okay. Okay, now excuse me, I do want to reiterate though, that you should have it. I mean anti-virus as the Mac continues to get a little more popular and mainstream, I mean people are gonna start wanting to attack it. It's one of those things where I'm not surprised more people aren't trying to attack it because they see all these ads and, they're like, shut up with the ads already. I'm sick of them. You know how people, hackers. >> They don't bother with those, you know. They don't take Apple seriously, I'm saying, okay? [ laughter ] But talk here about software and protection, just know that there's no 100% protection. >> Yeah. >> So if you have some software, even if you have a Tandy from software, you know, install, Tandy protection software installed on your machine, it doesn't mean that your machine 100% protected. >> Yeah. >> In the end, you have to be, again, be aware of what you're doing. >> And there's always new viruses coming out and if you don't update your definitions, then it doesn't matter. >> And the virus always come out before the definition comes out. >> Yeah, exactly. >> So there's always a window of kind of opportunity right there for the virus to get in your machine. >> Okay. This is a question from AliphGlass, I have heard of some new viruses that can target Macs. This is new. As until now, I have not heard of this. Is this new? As of now, I have not heard of this. Do you suggest a Mac virus scanner, free, if possible? So I know, you know, even when Apple's like Safari has typically probably been currently like the most vulnerable part where sometimes there're security loopholes, then even haven't outright told people what they are but they will update and patch them in a pretty quick time. But at least a virus, a Mac virus scanner that's free. I haven't used one. I know when there used to be a, well now it's Mobile Me subscriber, they used to have an application called Virex [assumed spelling]. I mean, they do have Norton Anti Virus for Macs as well. But maybe during the break, I'll take a look and see if there's anything off the top of your head that's free. Do you know of any of the top? Okay. >> I don't think there's any free when it comes to Apple, really. [ laughter ] >> Yeah. >> I love [inaudible] you need to. So, no, I would say no. Soon, go ahead and buy some anti-virus for your Mac but don't expect free. [Inaudible] [ laughter ] >> That's hilarious. Okay. Okay, here's a question. JJKaminski [assumed spelling] asks, well it was here but it disappeared. What is your favorite anti-virus software program? >> Well, I don't have any favorite, really, because like I said, none of them are 100%. They give you 100% protection but I used AVG free for my home computer and the reason is because I also answer the question here from Alley, Alice. >> Al, AllenIceman. >> Yeah. He asks about, you know, which one but a light weight. >> A light weight anti-virus software program. >> And the reason I chose AVG because kind of light weight. The problem with AVG is that recently it's been giving a lot of false alarms. >> Oh, false alarms? Okay. >> Yes. It would give something completely, you know, how say like? >> Like, an alert would pop up, but it wasn't accurate? >> Yeah [inaudible] that is not necessarily a virus. So you should be aware of that. And of course you know, it is really hard for anti-software to be 100% correct. They will give false ones some time. But so far, I still like AVG. I would definitely you know, think that is a good anti-virus software. >> This is cause it's simple and straight forward, basically. >> It's simple and straight forward and it's very light weight. Compare, if you, you compare to Symantec and MacAfee? >> Mm-hmm. >> AVG is a lot, a lot light weight, more light weight than those applications. >> Okay. Here's another question. Which of the free anti-virus programs is lightest, and gives the least false positives? So do you have any programs? >> Which one? >> Engine Julian. >> Okay. Engineer Julian. >> I would say that, you know, I feel like none of them are free. They give you free for thirty days or so. >> Yeah, that's always how it is. >> That's not free. I don't call them free. I think, the only one I think truly free is that, you know, that's probably this AVG. And it's free because you can use it forever, basically forever. It doesn't, you know, require you to [inaudible]. >> So if you don't have to pay forever, it's free. >> It is free, yeah. >> That makes sense. >> Exactly. The reason because sometimes the vendor say oh I give you this for free, but then after thirty days, no more free. >> Mm-hmm, mm-hmm, mm-hmm. >> And I think that's, you know, misleading. So, it's hard to gauge which one gives you the least false alarms, really. ^M00:10:02 >> Mm-hmm. >> Because it depends on what the computer is and it's impossible to really, to really kind of check to, you know, or to see which one gives the most false alarms, or even a right alarm. >> Mm-hmm, mm-hmm. >> But so far, I've been pretty safe with AVG. You can try other one like you know, like Arvast [assumed spelling] or some other one. I also use some of their anti-version from vendor that is not known in the States, you know, from vendor like Vietnam. Because the problem is that some virus come from China. It is funny that if you are infected with those viruses and use any of those AVG or even big defender or some known anti-virus software in the States and you scan them. >> Yeah. >> One end, you know, they do detect the viruses and they do remove the viruses. But by the time that they're done with the fixing, your computer has stopped working, because the virus actually, those new viruses, they actually replace some important file of Windows with the old version. >> Really. >> So that, those files removed, Windows will stop working >> Oh, wow. >> It's amazing, just like, you know, they replace your - >> I've never experienced that. >> Good for you. [ laughter ] But you know, it's very much like you know, some kind of disease that infect your arm and you know, to cure you, we have to cut off your arm. This is sort of like that. And by the time we're done curing, you've become disabled. >> Your arm? >> I just try to make an example, like, you know, if you imagine like - >> If the virus infected your arm and you wanted to get rid of it. No matter what you do, you have to kill off your arm. >> Yeah. So it's something like that. It infect part, you know, important part of the OS. So some anti-virus, actually, in Vietnam, they can actually restore those part with their holding system. >> Okay. I got you. >> But they're not known over here. >> Okay. So what we'll do is, actually, I'd like, we're gonna also talk about just, you know, being online and etiquette and we'd actually like you to send in, if you can write us maybe a couple of sentences of maybe some freak stories that have happened to you about, maybe you clicked on a link or you put in your credit card, tell us what happened with you and we can talk about them. But before that, we're gonna go to a break. We're gonna have a video about AVG, anti-virus free, the program that Dom has been so lovingly talking about and you guys have been asking about. But while we're doing that, send us in some of your little stories of stuff that's happened to you, and we'll share our own and we'll see you guys back in a second. >> Yeah. ^M00:12:19 [ music ] ^M00:12:22 [ background music ] I'm Seth Rosenblatt, Associate Editor at CNET Download.com, and today we're talking about AVG anti-virus free. In this first look video, we're looking at the latest release of the super popular security program, version eight. Some might say that AVG free provides the bare necessities, a real time shield to prevent infections, anti-virus, and anti-malware wrapped up in one engine, and a link scanner for web surfing with care. But they do more than an adequate job of protecting your computer. By default, the program is set to search for new virus definitions daily, but you can always use the scheduling tool to change this. Should a virus create serious system problems, AVG creates a rescue disc to scan your computer in MS-Dos mode. The program no longer heavily taxes your system when scanning, or when running in the background, and always proved effective in our tests. The navigation of the new version is much appreciated over previous editions, and is much easier to use. The tabbed interface on the left ably assists users in drilling down to the tools they need. But don't take it from me. Look at the behavior of other users. AVG free has seventy-five million downloads from download.com. It's hard to conceive of seventy-five million anything, but experts tell me that's a heck of a lot of downloads. [ background music ] I'm Seth Rosenblatt, and this has been a first look at AVG anti-virus free eight. Don't download anything I wouldn't download ^M00:13:47 [ music ] ^M00:13:51 >> All right, guys, we are back. How are you doing? >> In white and black. >> Thank you. In white pinstripes if you get it really close. Look at that. >> [Inaudible] >> Okay, okay. So Dom, during the break we were talking about some of the other ways that people can be safe, cause when people talk about computer safety and security, they automatically think about anti-virus, but there's obviously a lot more. You eluded to some of that stuff, how we're talking about you're your worst enemy, or things you should be aware of. So we kind of want to talk about, there's a lot with the internet being so big, and e-commerce being so big. A lot of you, like myself, purchase things online whether it's through eBay, do your online banking, and we actually, and you know, get flight tickets, put a lot of personal information online. So Dom, you had a few tips and suggestions of how to be safe, and some of those are Ennis >> Yes, sure, yes. I think, you know, a lot of people are doing, like, you know, banking and purchasing online now, especially with Black Friday coming up. >> Oh, yeah. >> So, it's very important to know that there's something called phishing. Phishing means that you know, you receive an email from you know, the email look like, say, from Bank of America, for example. But it's not from Bank of America but it looks just like from Bank of America. And then there's a link inside, and you click the link, you know, a website pops up and the website looks - >> Looks exactly. >> Just exactly like Bank of America with you know, the login and everything. But if you type in your user and password to login, that information is gonna be stolen. So the best way to do online banking is that you do not click on any link that's sent to you, even with the link sent from you, you know, sent from you from the bank, just open the browser and type in the bank web address you know, manually. Just type in www.bankofAmerica.com, for example, and then that way you're assured that you are actually at the website you want to be at. >> Yeah. >> And the second thing is that I would recommend using you know, multiple browsers. You can have like Firefox, IE, and Safari and - >> There's Chrome, there's Opera. >> There's others, two other ones, yes. So I would, you know, I would use one browser specifically for automatic banking or buying stuff, just one. And I would, I would, and I would not recommend using IE for it, okay? Do not use Internet Explorer for your like, you know, online banking or buying stuff online. Maybe use Firefox for that, or use Safari just for that. You should use that browser when you're gonna do something that is, that you would risk losing your personal information. >> Is it because, are you saying use it on one browser because it kind of isolates the activity just to that browser, so if anything goes down, you got, at least you're working in that kind of confined space. >> Yes. So each is limited. You know exactly where it is, and it becomes a habit, okay, if I'm on this browser, I need to be on the careful mode. It is like a serious business hint, not like surfing, you know, fooling around. Also, when you go to a website that you tend to pay money or something to do with money, make sure that you know, the address, the beginning, five letters of the address is https, with an S because that means its secure website. Also if some bank, you know, some banks, some credit card allows you to use some sort of like, temporary number, so you can, let's say the Bank of America would go in and you can create some temp credit card. >> Mm-hmm. >> Which has like, twenty dollars or sixty dollars, whatever amount you want to put there and it lasts two months. And you use that card to buy something online. So in that case, if you lost the number, it would not affect your entire main card. >> Limits your exposure. >> Sure. >> Okay, those are good tips. Now, I have a, you know, when you're talking about people phishing, and this happens to a lot of people, even people that are totally like, into tech. Sometimes it's like a late night and you're like, looking through stuff and you just click on something. I remember like, a few years ago, I got one of those eBay phishing emails. >> Uh-huh. >> And they asked like, oh yeah, you won this. And I was like oh, I just like bid on this thing, right? >> Yeah. >> And so I typed in my username and password and all of a sudden my eBay account was locked, and I was like what's going on? And someone had stolen my user name and password and was like, messing around with it. It was horrible. So, I was a victim. >> I think you're also, like, don't believe in stuff that is too good to be true or just so unexpected. >> You mean like buns of steel for life? >> Something like that [inaudible] if you try to get to a girl for a long time and she never replies to you. And suddenly she replies to you, hey look at my picture. I'm pretty sure that is not real. >> Wait, wait, you mean that Russian single girl is not real? >> No. >> Oh, my gosh. >> Now you have to go and change your password again. >> Oh, my gosh. >> I know. Too late. >> It's horrible. I sent her like thirty dollars a month. >> All right. >> Okay. >> You're rich. >> Okay. All right, guys. So those are good things to do. Have you had any horror stories with your internet security, like where you just kind of slipped up? >> I don't, but I do actually have, I have you know, people telling me a story. And I have people right now, sitting there right now, trying to fix their, the credit course. >> Credit history. >> History, because she got her's stopped, you know, compromised. And then by the time she realized that's the case, it was too late. There's too many carbons made under her name and social security number already. >> Identity theft and how it affects you and your credit is huge now. >> And also, it's also when you play games online, too. I mean, if play game online, even if you play Wow. Wow came out yesterday. And a lot of people are playing Wow, and I know the story of this you know, guild master, okay, you know guild in a game, right? >> Yeah, I know. [Inaudible] do that. >> All right. But anyway, they have the kind of you know, come on kind of good, like ton of gold in a guild bank. And the guild guard, guild master got hacked, okay, was hacked, and they disband the guild. >> No. >> And they throw away all the gold. I don't know what happened to that but it's really devastating for all the members. >> Oh, that is devastating, yes. >> Of that guild because think about how much time is spent on collecting all those. >> Yeah, getting all the gold. >> Gold and stuff and honor, you know, everything there. >> Yeah, and imagine the opportunities they missed in real life of hanging out with friends and socializing. >> That's true. >> No, I'm just playing. World of Warcraft is cool, I'm just goofing around with you guys. >> We're saying that so, so be careful and if you worry you're playing game online, do not, okay do not use a [inaudible] that is an executable file. Okay? >> Yes, don't do that. >> You want to launch the game from the icon, the circuit of the game, not from another software. Don't use another software to launch the game for you. >> And speaking of .exe files, Barrack Obama and Paris Hilton are not sending you direct emails to open up an .exe file. Don't do that. >> I mean Paris Hilton might send you her photo, but not to you, okay. So don't even, don't even think that it's gonna be true. ^M00:20:48 >> Okay. All right, cool. Let's go and jump in and get some questions here. This question is from Leafglass, and actually two people kind of talk about it, ZBoy4017 also asked about openDS.com. Is it a good service, and do you think it is one way to stay safe? >> If I'm correct about the open DNS. >> I'm not familiar with this. >> Me neither, but I think it's probably one of those service that allows you to map your static, your dynamic IP address to the static one. It's kind of like, but it means, DNS means dynamic, no, domain naming system which, for example, if you go to CNN.com, the reason it's gonna say CNN.com not some number because there's a DNS service. So I'm not sure. I think you know, I think you should not do anything with online security, unless, unless you, unless you, you know, like reveal your domain, your DNS domain. So just keep it for, keep it a secret. I personally, I use the dynamic DNS myself service, and if you don't let people know what your - >> What it is. >> What your domain is, then it will be fine. >> Okay. Excellent. Now, this one is for HipHopForPres, what's up? He is asking, what's up fellows? What is spyware, or what is spyware and is it worse than a computer virus? He's asking about what is spyware. >> It is, it is, I think it is a very fine line between spyware and virus because they're kind of the same now. In the past a virus, many years ago. >> Yeah, yeah. >> The virus tends to cripple your computer, or do a joke on you. Basically, harm your computer. But now they do kind of the same as a spyware. Spyware, basically, they one that collect your personal information, and some of them are not that dangerous. It's just collects your, how often you buy something, or they try to deliver ads to you, which is annoying, more annoyance than anything. But now some of them start collecting your personal information, your name, your social security number, and your credit card number. So they're kind of the same, they're sort of the same now. >> Is it, do you basically, I'm just saying because I don't deal with this kind of stuff much. >> I think the main difference, the main difference between spyware and a virus, that virus tend to become completely. >> Try and cripple your system. >> No, no, they try to completely hide itself. You don't know that it exists. >> Oh, okay. >> The spyware can be in the form of some other software that is more like, benign. Like you can download something, a toolbar, for example, supposed to be helping you. >> Yeah, yeah. >> In fact, it's not really helping you. >> In fact, it's actually collecting data [inaudible]. >> So spyware is more like, you know, is more kind of, you know, this guy's software that you can see, that you can interact with daily. When you turn on the computer, when virus that you don't know, you just don't know that it exists unless you have some kind of detection. >> So then a virus, I mean you know, bringing down a virus, someone could like double click on a file and get a virus, whereas the spyware, they have to actually install an application that's running and collect the information. >> The thing is some - >> But they're starting to behave a lot like each other more and more. >> Yes. But the thing is, you know, you have to, if you think about it, you have to do a lot to get infected, that is a misconception. Sometimes you just click okay once. Just click okay one time, and then it's too late. >> Yeah, yeah, yeah. >> So when you see something pops up like do this, make sure you read the text. Cause sometime you're doing something, and then something pop up and you say oh get rid of it, and it's open. And that, you know, when you know, trouble starts. So just pay a little more attention to the message, and make sure that when it pick okay, you know exactly what you are doing. >> Okay. Excellent. Okay, this question is from Meatboy43, interesting name, are there any good boot tools to remove a virus after you have been infected? >> Boot tool, what is boot tool? >> Maybe on boot, like when you boot up your system, are there any tools? >> Normally, there's no tool there. If you can boot your system and read the hard drive, you know, before the OS boots, you can actually do a lot of things. If you know where the virus file, you can delete it, you can remove it, you can, basically, [inaudible] those files. But the problem is, this is hard to boot with down the OS, right? You have to have some sort of OS to boot it into. So it just depend on the virus, really. But if you can, I think the best way to remove a virus that you try to find out what file it is. What is the file, where it is, and if you can put that hard drive to another machine and look at it from another machine, and it's sort of easier. But I think, you know, removing virus is very, you have to, you know, go to, depending on what virus it is, it cannot say, you know, like is a good tool for this, you know, depend on the virus. >> Okay. Excellent. All right. Next question, this is from AllenIceman. AllenIceman asks, I am getting a new laptop that comes with 80211N, but my current router is only G. Now right off the bat, they can talk to each other, but the question is can you suggest an N router than can make it to my basement. >> Yes, it depend on where your basement is. It's hard, but let's say that your basement is not that far and it's a regular home, I would recommend the Belkin N Plus. I just reviewed a few days ago. It is probably one of the routers that's got the longest range. >> And can, like, go through, has the best ability to move through walls. >> Yes, possibly. Again, depend on your construction and everything. >> Yeah, it depends on construction and steel. >> But I think that's one, in my opinion, in this year, probably the one with the longest range. Of course I haven't used that one for a long time. I don't know how stable the signal is after a few days. But so far, is in the very good wearer. So is N one, no, is the Belkin N Plus, and it costs about a hundred bucks so it's a very good deal. >> Okay. Excellent. Okay. Here's a question. This is from TM underscore thirteen, TM underscore thirteen asks, and this could be a he or she, I think it's a he though. I received emails from friends, and it turned out to be some contents which I am sure they are not sent from my friends. How do they get to be sent from their email addresses? Love your dimples, Dom. >> Well, I'm blushing. Well number one, I have only one dimple I think, so I think - >> Really? >> Yeah, I think only one. >> Okay, I'm not gonna look for it but that's - >> Well, it's very easy to pretend to be the sender of any email address. It's the same thing as if you send somebody a snail mail, a normal mail. >> Yeah. >> You can put on the return address whatever you want. So it's the same thing, you know, if you set up email in a email client, you can change the - >> The return address. >> Yeah, that can be whoever you want to. So it is very easy. Okay? It's a lot easier to do than counting my number of dimples. [ laughter ] But thank you. >> All right. Love it. Okay. This question is from Aman720. I haven't read, I'm just gonna pull it up right now. I'm not sure if this is a virus or something, but the black Mac book I bought last year is having some problems shutting down. When I click shut down, everything goes away except the dock. >> I'm sure it's not virus. It's just Apple. Because virus does not, does not shut down the computer. >> Yeah, yeah. >> It wants the computer to run to do bad things. So it is probably Apple. >> It is, I mean yeah, it probably is the computer. I don't, I haven't experienced this. I mean it sounds silly to say oh, reinstall the OS, but I mean, that's - >> Go buy a PC. [ laughter ] What I'm saying. I mean, bring it back to the store - >> It basically means it's hanging on the final set. Because a lot of times, when you shut down a Mac, everything turns off and shuts off, and the dock drops down. That's the last thing that you see that happens. So I would say it's probably more, I would hint and say it probably is more of a software thing than a hardware thing, but - >> But it's not the last thing you want to see, so go ahead and go buy a PC. >> Okay. Thanks, Dom. All right. Any thoughts for extra protection when using a public hot spot. Also, what's with the ad hoc networks I see that are free. >> Okay, so extra protection using, I don't think you need any extra protection, really. You just - >> Just be aware of what you're doing. >> Just be aware of what you're doing, just like normal, okay? And you should be, you should be, you know, at the same level of carefulness even when at home. Being at home using your own wireless network doesn't mean that you are safer than using a public wireless hotspot. The difference between ad hoc and, okay, ad hoc and, is called infrastructure. There's two ways, infrastructure and ad hoc. I forgot what ad hoc means, its' some kind of Latin words or something, they pair something. But ad hoc mean you can connect to another Wi-Fi device, pier to pier. So when you use ad hoc, only two machines can - >> Talk to each other. >> That's it. No more. When if you, infrastructure which is, you know, the other option, you probably don't see it, but the other option of connecting to a hotspot, that's called the infrastructure, it means many devices can connect to one access point at a time. So we generally do not use ad hoc. And I don't see any reason why you'd want to use ad hoc if you are on the go, really. Actually, it's safer to turn ad hoc off. You can go in there, you check the box and say, you use only infrastructure. You don't use ad hoc, because ad hoc could be a potentially, you know, a loophole for bad guys to come into the computer. So don't, if you travel, don't accept ad hoc, ad hoc kind of how you say, in file, whatever. >> Okay, okay. Cool. Excellent. >> No ad hoc. >> No. Say no. Okay, guys. It looks like we are all wrapped up for today. Come back on Monday, because Dom won't be here. I'll have Declan McCullagh here. We're gonna be talking politics about you know, the future of you know, what direction technology and how it will be affected with you know, the new regime that will be coming into play and how you know, things will change for us, or potentially change for us. So come back on Monday, again, eleven-thirty AM West Coast time, two-thirty PM East coast time. >> And make sure that you handle yourself well. And be safe. >> Take care of yourself and be safe. >> Yes. >> Be safe friends. >> Right. All right. Bye-bye. >> Okay guys. We'll see you next week. Thanks. ^M00:31:06 [ music ]
