I was having the same issue with Avast! Service and Self Protection not starting. After following the instructions twice, it would still not work. Avast! uninstall through Programs and Features also would not work.
I’ve found the reason, though I’m not certain which one actually caused this.
I rebooted into safe mode again and used Aswclear to uninstall Avast! I rebooted and shut off both Windows defender and MalwareBytes file protection and unchecked start on boot. Rebooted again and installed Avast! successfully.
I suspect it’s MalwareBytes Pro version that was causing the conflict, but someone will have to confirm that.
Windows 7 64 bit.
