Any time I want to do a scan (quick, full or others) in Avast Free Antivirus 6.0.1000, I got a message from my OS (Vista Home Basic SP2 32-bit) that AvastSvc has been stopped. When I try to redo the scan it runs and finishes successfully. Could anybody say why it stops and what should I do with my Avast?
Update:
The problem has been resolved by complete Avast re-installation.
