F/P or Not?

[DedHed]

I ran a scan on March 8th and Malwarebytes said I had an extension mismatch. I quarantined the file, but noticed later that Windows Defender was disabled and any attempt to start it resulted in a warning stating that the "application failed to initialize." Before I restore or delete the file, I'd just like to know if it may have been malware or a file used by Windows Defender. Thanks for your time and help.

That should not have anything to do with windows defender.

That directory/file is is just for windows search.

Extension.mismatch means its an executable file in a non-executable extension.. for example its an .exe file but with a .log extension

Malware commonly does this.

You can restore the file and see if it allows windows defended to start but i would be surprised it it does.

You can also zip the file and attach it here and we can analyze it.
