It's been a while since I've installed any protection on my new PC so I'm probably going to get infected or something sooner or later. What antivirus software do you use? I'm going to get one soon.. and no Norton.
Download '360 Total Security Essential' (formerly 360 Internet Security), It is the best free Anti-Virus.
Plus an upside to this is that it is updated regularly and the is no paid version its 100% free and it uses multiple AV engines so it has 3x-4x protection.
