Hi,
We are so happy to hear that the issue is been fixed. But in case if you face the same problem again, you can do a clean reinstallation of avast! from the scratch.
Download and save the avast! removal utility from the following link.
hxxp://files.avast.com/files/eng/aswclear.exe
But before running the removal tool go for.
avast! UI -> Settings -> Troubleshooting -> Uncheck the Enable avast! self-defence module and click on OK.
Run aswclear.exe and make sure that you reboot the machine once its done.
Download the latest avast! product that you have purchased and install it. Hopefuly all the issues will be fixed by now.
Have a wonderful day, Good Karma!
