Which Anti Virus your used.

kaspersky

dr. web

I am currently using Kaspersky and pretty satisfy with it..

I'm using avast...pretty good with regular virus database updates

kaspersky for heavy pcs and avira free version for slow pcs they are top

Avast and Avira.

I've tried many of them, Avira is ok but I'm going back to NOD.

I use Comodo Dragon Internet Security. Before my laptop would always get infected by those fake spyware viruses even with protection.

i got a free years trial with Trendmicro titatium is pretty good but its very paranoid of keygens etc :whistling
i used to use avg2012 up untill then

I am using East Node and Avast...
And both are working well
