I use free AVG on a Vista machine and free AVAST! on an XP machine. No
problems with either application. If you have two PCs, there is an
advantage having two different applications in that it is less likely
both machines will become infected by the same virus. As stated many
times, use only one anti-virus application on any single PC.
Have used both, but settled for Avast for the past two years on a couple
of machines, one running XP Home and the other Vista. It works quietly
in the background, virus sig updates can happen 2 or 3 times a day and
never need a reboot. The only indicator is a slightly American voice
quietly announcing, "Virus database has been updated." I find it kind of
reassuring, which it's no doubt meant to be. Very rarely there is also a
program update and that may require a reboot. I think both are excellent
considering they are free, but Avast seems to have greater
configurability (IS there such a word?). Seriously, you can use it
without problems - at least that has been my experience for a couple of
years now.
Hope this is helpful,
