Kaspersky is the best, IMO. They protect your PC seriously. Even sometimes it make your PC runs slower.
my vote for kaspesky too, but it doesn't make my pc run slower and this has been asked 100's of times..hehe
LOL... Yeah but it happens on my PC. When I pause the protection, my PC run faster/normal. Or my PC need upgrading? hehehe
NOD32 is very good and very light on resources aswell, kaspersky is also a popular choice, but because of it's small footprint and super fast scanner, I prefer to use NOD32.
Norton Anti-virus is rock solid but it is not free and not fast... I use Anti-Vir, it is free and fast Got my point ?
i have not ever used kapersky but i have heard alot about its functioning it really has a good performance
I like NOD32 can block most of the threads. (I said most because sometimes i still got infected and have to restore backup)
