When I start a scan, quick or full, the scan starts real slow, the mouse barely works (lots of cpu being used. I can’t tell what is using up CPUs, it’s erratic). After a while the speed increases and the mouse is functional and scan completes.
The system is XP Home SP3 2 meg ram on a desktop, AMD 3000+.
When I installed avast, I had the same mouse problem, but I rebooted and when I did, my desktop was gone, just the default windows blue screen (not BSOD), but the mouse worked and I reloaded my desktop and everything is fine. Avast works fine, except for the on demand scan/mouse issue. I only have file shield installed and default settings. No other AVs, it’s clean.
I have avast on an older P4, 1meg and no problems what so ever.
