Avast will no longer startup - shield in tray has a white X on it. Worked fine for some time, but now won’t start. When I try to start from the UI I get various error messages including the above. Cannot start the Windows service manually either.
So, I uninstalled and then reinstalled. After that Windows would not even boot! Got a flash of a blue screen and then a reboot. Had to start in safe mode and go back to a prior restore point.
what antivirus did you have before you installed avast ?
have you uninstalled it ?
have you run a removal tool after the uninstall so all leftovers are gone ? find one here http://uninstallers.blogspot.com/
