Everything is now working properly. Not sure what happened but this is the second time I've had a major problem after an Avast Update. The first time caused my computer to freeze up, crash or whatever you want to call it. I kept getting a "Please Wait" message with "bullets" going around in a circle. I kept waiting, and waiting and waiting and nothing happened.
It took me several hours to fix the problem.
I'm not sure what's going on with Avast but they need to get their act together or they'll lose a lot of people.
I'll stick with them for now but I really don't need issues that caused my computer to malfunction, especially when it's not me that caused it!
