Hatim,
I used to use a Nvidia TNT2 with only 32 Mb and it worked fine. I now use an ATI Radeon 7000 with 64 Mb and still no problems. As far as eye candy goes, you can change the skins if it is too much for your system, although with 64 Mb on your video card, you should have no problem at all.

There were some problems in the past with memory and shut down times, but the Avast team solved them. These problems were brought to their attention through this forum and with the back and forth discussions, the compatibility and slow shut down are no longer. Try to mention problems to companies like Symantec (Norton) or the other big ones. Forget it.

I have tried quite a few antivirus programs and I have concluded Avast to be the
best (in my opinion). The updates are quick and constant (no waiting weeks for an update like some other companies), the email checking ability is by far the best I have ever used, and the forum here is great. I enjoy the forum even if I did not use Avast. The folks here are helpful and will help you no matter what.
And like someone else said, if for some reason, Avast does not work on your system or you don't like it for some reason, it's easy to uninstall.

I hope that I have answered any questions left about Avast.
BTW - My Avast notified me and stopped the MyDoom worm in its tracts before it infected my computer. And I have received more than 600 of this pesty virus since Monday.
