Navigate to C:\program files\malware bytes antimalware and renaming the file "MBAM.exe" to something else, say, "Moon.exe" and see if it can be run then.
You have a rogue antivirus program installed. MBAM is usually pretty good at nailing these.
Once the scan is complete you will be presented with the result: select "remove" (which will quarantine them) and a prompt to restart may appear. If so, restart promptly.

Another thing to try if this doesn't work, reboot into safe mode, and see if any of your scanners will operate in safe.
