Do NOT use avg, its one of the worst free av out there. just sayin...
(it actually would be considered scareware imo, it scares you into keeping/buying it by giving you obvious false positives, yet people still use it and recommend it...)
Anyway, dont use free trials. You only use a trial to test out whether or not you want to buy it...
There is plenty of free and/or open source software out there, there is no need to try and use free trials.
Now you can get decent protection for free.
Free AV, there are lists of them, but i like avast ( http://avast.com ). It has good real time protection, pre-boot scanner, auto-sandboxing, and the scan detection/removal rate isnt bad. Could try MSE or avaria as those are 2 other good ones. (anything but avg....)
Free malware scanner, malwarebytes ( https://malwarebytes.org/products/malwar... ). Its a scanner the can detect/remove pretty much anything. viruses,malware,spyware,adware. And has the highest detection/removal rates in the category. Even paid AV support has been known to tell you to download this to get rid of infections lmao
Free firewall, comodo ( https://personalfirewall.comodo.com/ ) make sure you are getting just the firewall and not the av. The firewall is free.
you can take it a step further and get sandboxie ( http://www.sandboxie.com/ ) to choose to run programs in a virtual environment, so they cant do damage to your computer. You can run programs you dont trust in it. Also you can run your web browser in it, so you will be unaffected by any drive-by downloads that can infect you.
And to also help id suggest browser addons.
WOT (tells you website ratings based on peoples feedback. can help you avoid shady/phishing sites).
Adblocker plus (blocks ads/popups, which can help you not end up going to bad sites by mistake).
browser protect (helps prevent browser hijacking/redirecting)
That together offers quite good protection from everything but complete ignorance. As no software can protect your from that... some of the more expensive paid software can help idiot-proof things and offer better protection from that.
Also paid AV/security software is geared more towards businesses.
(i mean how many people try to randomly hack into home networks? well unless you are maybe super rich, but then obviously you can afford great software).
Most all infections are gotten from either just plain ignorance or through file sharing. Well eliminating file sharing eliminates majority of possible infections lol.
EDIT: i always see colin posting the same stuff on here.
Which either he is a stone idiot or maybe trying to scare people into buying AV software?
I have used free/no protection for over 10years, NOT ONE virus/malware.
I literally can not see how its actually possible to get infected with viruses/malware, especially with the tools they have now.
Really using all this is like constantly using cold medicine. You really dont need to take cold medicine when you are not sick. But prevention by eating right and eating lots of oranges will keep your from getting sick in the first place. And if you take precautions in hygiene and when going to public places, you will probably never get sick.
If you avoid things that give you viruses/malware, you wont need av software in the first place, so why the fk would you pay for something like that? something you dont need at all in any way, not even free protection.
Well there is no such thing as a paid AV software that can completely keep you safe...
You want something that is almost guaranteed safe, and 100% free, 100000000000000x better then the most expensive most highly rated av software?
use linux. If you think "macs dont get viruses" ppsssh, use linux, there is 1000xs fewer viruses/malware lol.
The less popular the linux distro, the fewer malware samples there will be.
As every linux distro is a different OS, so a strain of malware for linux would pretty much only affect the 1 distro, and there are thousands upon thousands.
Really you only need as much protection to make up for you lack of common sense (though it also depends on who else will use your computer, having people under 18yrs old, might not want crappy protection).
As most people who are computer illiterate or kids who dont really know much of *** they are doing, are just begging to get viruses/malware. (using analogy above, those people would be like people going out in dead winter while its snowing naked, while sick people are coughing in their mouths lol)
