AVG, is up with the best of em.. type free AVG.grisoft.com in your seach bar.. its not a trial.. stops pop ups and easy on your comp and protects your computer like a mean dog : )
Best AND free... AVG. phy333 gave you the link. And yes it's STILL FREE. I'm not paying for it (6 years), my mom's not paying for it (4 years)... my sis loves it, she dosn't pay for it...

They have network and corporate versions that they charge for, but their free version 7.5 is easy to use, and updates and scans daily. Not a trial... FREE.
Avg anti-virus . thats free
some people like AVG from Grisoft

I don't like it.
AVg used to be the best ...went commercial...get Avast. Works best with an extra ram card . Back it with ad-aware and SpyboySD, two old standbys!
