I have tried at least ten different anti-virus software programs, and AVG is the only one that doesn't slow down my computer or cause other problems/conflicts. I think you'll be pleasantly surprised, Jenny.
Hey, about once a month I also use Trend Micro's free online virus scan, HouseCall (
http://housecall.trendmicro.com/), as a backup in case AVG missed something.

The full purchased software version of Trend Micro really slows down my computer, but by using the free online scan as a backup scanning source, I just get a wee bit of added protection.
Happy Thanksgiving!
