In response to @KillerRabbit

In my opinion, it is a bold strategy. Tried it myself, but sometimtes it is impossible to evade viruses, especially if you use the internet proactively.
I had Kaspersky but refreshing it was a pain in the ass, however i still think its the best. Now i use Nod32. great web protection, finds malwares quickly AND most important: its fairly easy to renew license with Tnod.

I tried avg/norton/panda but they were not good enough for me.
