Conflict with screen saver

I searched for this topic, but did not find it. I’m sorry if this isn’t the place for this post.
I’m running XP sp3, have the free version of anti virus for about a week now. I have the scan scheduled for 2am and when it starts my screen flickers and the Comodo logo shows through the screen saver (3d pipes). It looks like lightening in the room from the flashes on the screen. The other morning the computer was locked up, first time ever. I have had Comodo before without this problem. Any ideas?


Have you tried adding the file to your safe files list and see if that solves the problem?
You could also try adding the executable to your exclusion list for the AV and see if that fixes it?
