This is the second time in a couple of months that I have been unable to "Fix" Avast pro. Running win7, no other antivirus programs other than Malwarebytes. I do my "maintenance" work: CC cleaner, wise disk cleaner and wise registry cleaner and Glary utilities, and it seems after those run I get the error message. I had to uninstall and reinstall the last time (following the directions in Safe Mode) and it worked for awhile. Now it's up to it's old tricks again....Help!
