Starts scan, quickly stops and says no threats, also 0 files scanned run<2sec

Hello, I go to manually run a scan, immediately shows no threats found, runtime 2 seconds or less and file count is zero. My suspicion is I have been hit with something disabling the scan program? thoughts anyone?

Thanks!

any error messages on avast?

have you tried avast repair?

What scan are you running / what are you scanning?
