Antivirus? what is that? I'm kidding...
I just don't need it, well, I use free avg but its only to be at peace with my conscience. To stay safe on the Internet, I use Spyware Doctor since spyware is the most your gonna get in the web.
When I got my PC I used Norton and then Mcafee, however I came to the conclusion that antivirus are almost useless.
I've heard great things about NOD32, but also good things about Kaspersky, why do you say its bad? Is that from personal experience?
