Which Anti-Virus should I use?

Hey whats up everyone! I was just wondering what Anti-Virus I should use that is compatible with hacks and is good. I am on Windows Vista laptop. VGN-NR385E. Its a Sony Vaio. I want one that isnt too big but works well! Thanks!!

Try Using Kaspersky Internet Security. Low False Positives and great for haxors. :] And it it isn't annoying like other Avs. One of the best detection rates.

you should try avg its really good , that waht i have and its easy to modify
