Dear Jasmine,
You don't say what you use your computer for, and that will make a difference in the answer. I've actually been compiling free download.com links that I've used with a great deal of success for the past six years, for personal use. Note that the links are for personal use, and not for use within large companies. I'll tell you, though, if I owned a large company, I'd pay for the software for my employees' computers, because the free (slightly limited) versions have treated me so well at home.
Briefly: I have two computers at home. The desktop was built for me by an ex back when I went back to school five years ago. I used to use it for downloading music, but there's too much issue about file sharing and copyright. As a paralegal, I don't want to do anything that will jeopardize my job; that's my choice and I wouldn't tell you what to do. I use my laptop to maintain my website. Both machines are used for heavy internet surfing, blogging, and online shopping. (The laptop, with its faster processor, is used more with my voice software, which I can't run on the desktop. I smoke next to the desktop, because I always have. This is icky - and my perpetually filthy monitor will attest to this - so I don't want to smoke near the newer laptop.)
You'd said that "nothing is free" but I'm sure you've given to your community. Software writers do the same. They also offer different levels - for example, personal versions for free, and professional versions for a fee. I've also read that some freeware is given as such to promote other software in the line, to grab one's attention. Because of physical limitations, my work hours - and my salary - are limited; what should be surplus for my computer mostly goes to doctors and health insurance. I grab freeware when I can, and donate when asked.
From Wikipedia:
"The term freeware was coined by Andrew Fluegelman when he wanted to sell a communications program named PC-Talk that he had created but for which he did not wish to use traditional methods of distribution because of their cost.1. Previously, he held a trademark on the term "freeware" but this trademark has since been abandoned. Fluegelman actually distributed PC-Talk via a process now referred to as shareware."
First: virus protection. I've tried several of the big-name virus scanners (especially when I was entitled to an academic discount!), but the best I have ever used was recommended to me by my sister-of-choice, Heather. When she was working at an ISP, they told all their customers to download AVG Anti-virus. I wasn't using CNET yet, but as you can see, this is a highly rated product! As of this writing, they're up to version 7.5 which you can download for free, here. It's caught things that the "bigger" names have missed, doesn't bother my non-threatening files (my mom's Anti-virus scans every document she opens, even if she created it; it seems to take FOREVER!) and AVG is constantly updating and constantly improving. The aforementioned desktop was purchased when a top virus "protection" software allowed an infection to infest my computer. After I'd gotten the desktop, I burned and loaded AVG - and it fixed the problem. My mother can't wait for her paid subscription to another Anti-virus to expire so that she can download AVG - the tech support at the pay place is lacking. Severely.Note that the free version looks for viruses, but not does not include Anti-Spyware, Anti-Spam, or a Firewall. (I've never looked at their other software. It does constantly download updates for you, so that you've got excellent protection.I'm so happy with this product that I'd pay for it. It's free for personal use, or, if you want to install in a small office, the price is very reasonable. There are many different packages for the commercial user; you can build a bundle of whatever you want, for as many computers as you need. I'd looked at building a package for three computers, and it was less than a year subscription of the package my mom uses, for her ONE computer.
Your next point was spyware. A great deal of the spyware is malicious (bad). It's often installed without your knowledge, when you visit a site. I'm fairly certain that a lot of spyware is, in part, responsible for the hacks that I keep seeing on MySpace, where a user will "post a bulletin" saying that "I tried such and such, and it's great!" - and I'm not sure if it actually steals your account password, or if it "posts" while you're logged in.I clean both my computers, every week, for cookies and spyware. I clean out the cookies, first, because I run a full spyware clean, and there's no point in asking the spyware search to clean stuff that will be discarded, anyway. (To clean out cookies, I've been using Steve Gould's Cleanup utility with great success. Free, though he doesn't mind a donation.) I've been using Ad-Aware successfully for over five years. It will clean up ALL the crap you've picked up by surfing. all those popup ads dump spyware, you know. You can get the free edition of Ad-Aware directly from download.com. It's rated highly by CNet and by CNet users. AVG also offers AVG Anti-Spyware Free but I am old and set in my ways, and despite my loyally to GRISOFT, I haven't downloaded this yet. The free version is available on the GRISOFT home page, here.You may choose to get rid of any spyware that you see. Personally, I allow what I've learned is called loyaltyware: This is software from merchants - stores - that keeps track of who should be paid for visiting web sites. I subscribe to shopping sites that give cash back, and they let me know when I've visited a site that qualifies for a bonus. Ebates's loyaltyware lets me know. (For example, if I go to a certain site where I buy get over-the-counter pain supplies, I'll get a small popup that says You qualify for a 3%cashback for your purchases at thisstore.com and, when my purchase is complete, I'll get an email saying how much I earned. I intentionally installed the software so that I get these alerts when I browse, so that I'll get my bonuses if I stumble upon a cashback site and don't known it. If you'd like to see how loyaltyware works, I found a small group of online tutorials here.)
Your suite also includes, you say, a firewall. If you're online, you really must have a firewall. The whys are listed here on ZoneAlarm's web site but, basically, any seller or dictionary will tell you that opening a gateway to the Internet also means that people can get in from the outside. A firewall only lets authorized traffic through your gateway.After reading an excellent Q&A on CNET, i got off my butt and downloaded a firewall; i went with the very highly rated (by CNET and by users) Zone Alarm. (Read user reviews here; free download here on download.com.) I based my choice on the number of downloads, the CNET review, and the user reviews. (what good is a perfect review if only four people rated it? ZoneAlarm was rated by 1,322 people as of this writing.)
If you choose not to accept my recommendation, here are some other free virus scanners on download.com, free spyware remover downloads on download.com, and free firewall downloads on download.com, sorted by user reviews - highest, first sorted by user reviews - highest, first. Feel free to adjust the breakdown to narrow down your operating system - Mac, Windows [version], etc.
I'm obviously a fan of CNET and download.com. If you do a search for freeware, you'll find a lot of other sites with great stuff.
(I use some of them, but don't download unless I can read unbiased reviews, such as those on CNET.)
I'd begun writing about this for my friends, who seem to get attacked weekly on blog sites. I don't blame the sites; I blame the trash that gets in there, like riffraff visiting your favorite neighborhood haunt. I hope you can use it, even if you never wind up coming across the page I'm working on. CNET is a community and, like neighbors should, I'm happy to share what I've gathered so far. I do hope that I was able to shed some light onto the subjects for you.
