Seriously. I remember reporting and debugging this issue with Comodo a few years’ back. They fixed it ages ago and never had this problem since.

Just recently thought “hey, I’ve been using free Avast for years, might as well give them a little cash”, uninstalled Comodo, bought Avast IS with the firewall. The long-forgotten DPC issue is back. Seriously, fix this thing. My sound stutters like crazy, even chopping the video.

Confirmed using dpclat. It does not look good at all.

EDIT: Here’s what happens if Avast tried to do something in background after PC has been running for over one day. Mouse cursor stuttering. Unusable PC. Had to reboot.
