I have my PC, my fiancees laptop and PC, and my mums PC running the same software. It has been running the software for a long time but today every single machine fails to start into Windows, and begins automatic repair but cannot repair anything in the end. I booted into safe mode tried ticking launch services only on MSConfig, restarted but no luck. I disabled Comodo and Avast restarted and managed to get back into Windows, and uninstalled Avast.
I then ticked Comodo to renable it and restarted the PC and that loaded up no problem, which tells me something has gone wrong with Avast. Last night I did have a strange firewall alert for Avast but I accepted it because I thought it would be trusted.
The alert I got was a connection request for:
C:\Program Files\AVAST Software\Avast\Setup\2dc10cdb-b87a-4327-8a36-0358ccb8a9f9.exe
Not saying it could be that but I have never had anything like this ever! Especially the way it managed to stop 4 windows machines booting into Windows. I checked Avast Forums, Comodo Forums, tried searching Google for the error for the last 24 hours to see if anyone else had the same issues. Never did find anything though. Really strange.
Fixed 2 PC's so far luckily. Even when using MSConfig and selecting to startup absolutely no startup items, it goes in a reboot loop. Comodo won't let me uninstall in safe mode, however Avast does and as soon as Avast was uninstalled the system booted to windows fine.
Found the forum post on Avast reporting this:
