A lot of posts here talking about hung scans. I have a slightly different issue - the scan itself doesn’t hang, but the Comodo GUI does.
A couple of minutes after starting a full scan of My Computer, Scan and the CIS Console windows both stop responding - they don’t update, you can’t move them or close them and they don’t even repaint when another application overwrites the screen. Windows also becomes very “lumpy” - even 3D rendering doesn’t slow down my system this badly. :o
When the scan completes the Comodo GUI becomes responsive again.
