Every time I try to run a full scan, Comodo hangs up and won’t complete the scan. Where it hangs up is always on a different file. The only workaround it to shut down and reboot my computer.
Have you tried this?
If that does not work, you might need to do a clean reinstall following this guide:
A clean reinstall solved my issue of full scans hanging. I have other issues now, but at least my scans complete.
