Hello everyone,
I've been having problems recently with Avast freezing during scans, and due to the incredible efforts of Igor and Vlk, the problem has been solved. It was caused by conflict with Kaspersky drivers, probably installed by ZoneAlarm, which it would seem uses the drivers as part of it's program. I'm wondering if anyone else has been having a problem, but more importantly, would you mind checking to see if you have any of these entries on your PC. The typed one is the one I had to delete to stop the conflict, the ones in the image are entries for the offending item ('Klif') which are still on my system.
C:\WINDOWS\System32\Drivers\Klif
Many thanks for any help.
Graham.
