Windows defender offline scan not working

broken image

When I run Malwarebytes it finishes the scan but it doesn't find the virus. I've tried doing that and it doesn't fix the problem. I have Windows Defender and Malwarebytes Anti-Malware as security on my computer and when I try to run a scan on my computer to detect the virus the scan stops midway (for Windows Defender ) and says that it could not finish the process and that I should restart my computer to fix the problem. I seem to be have a virus/malware in my computer that keeps turning off my defenses before they have a chance to detect/delete the problem.
