I'm running XP with SP3. My free Avast kept stalling at about the 5% point. Finally got the XP error check on C: to run with both boxes checked - no help with problem. Avast still hangs. Finally I scanned 'Folders' on C: and found out that it's the System Volume Information folder that hangs it. Is this a known bug? Any workaround?
I did try updating Avast program. And I went to ControlPanel, Add/Remove Programs and found there was a 'Repair' option for Avast - no help.
