Re: Corrupt file
Run a scan with Malwarebytes Antimalware and make sure that it's not a piece of malware/spyware.
If you were getting that error on startup, either the malware is already gone (hence the error message when it tried to run on startup), or it made matters worse. I'd say the former, but run a scan just in case.
