I had the same problem after updating to Internet Security version 12.2.2276 on my Windows Surface 2 (Windows 10). Using the Control Panel I selected Uninstall, and then Repair. It said repair was successful, but after restart, I had the same problem.
The solution was to uninstall Avast, restart, then install Avast again. It seems to work fine now, so I don't know what happened badly in the update process.
