ESET Smart Security

i tried all the above Antivirues the most powerful is Webroot i currently use Microsoft Security Essentials but every one of the above has its disadvantages

Im using NOD32. Its doin a great job for me

i use Avast, and is preety good .

karspersky, i use because is good for my pc

KIS is the best but if you could get un-blacklisted key.

yeh we win kaspersky..

Eset NOD is the best. I have been using it for 2 years.

I've been using Kaspersky for a couple of years and I like it

Using NOD32 AV (not the smart security) for years, still good
