Question

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.

any other security programs installed?
what antivius did you have before avast?
have you uninstalled it?

No other AVs installed. I had MSE prior only because I couldn’t get avast to work, always the mouse freeze until now with this version of avast.

Yes, MSE is uninstalled.
