Sounds like you have fake spypro variant.Try running something like McAfee stinger which is a free stand alone application ,that specifically deals with the fake type (including spypro) malware.
Disconnect from net and disable your avast ,and run stinger in safe mode.

Some of the spypro malware can affect your system files so its possible some of them are corupted.
