NOD32 is a great Anti-Virus. It uses less resource, and does a better job than Norton. Also Kaspersky is like $69 for a single year, but NOD32 is $58-$59 for two years. I am a Anti-Norton person.....LOL. Anything is better than Norton in my opinion.
Also AVG is not going to have a free version anymore.....they are ending the free version this month. Avast is one of the best free versions out there.
