Windows Defender Offline doesn't even work anymore as well because when I run the scan it stops after about %85-90 done and says that the scan could not be completed and that I need to restart my computer.Windows Defender Offline is a powerful anti-virus tool built into Microsoft Windows 10. Well now I'm having the same issue and I ran the Microsoft Windows Malicious Software Removal Tool in safe-mode and while the scan was running it said that it had detected 16 potential threats but when the scan finished it said that the computer was clean and the program didn't find any threats which leads me to believe that the virus is doing something to stop all of the scans before they can find and delete it. would show that it was up to date and everything was 'good'). After I found the infections and deleted them I realized that the virus had been preventing my computer and Windows Defender from updating for over a month and a half (even though the computer would show that the were no new updates available and W.D. I took a look into it and did all the basic stuff: run the scans on safe-mode with network on and off (virus would still stop the scan before it could finish), run task manager to see if I could find any odd programs running in the background, and eventually I ran Windows Defender Offline from an USB and it found 13 severe infections in my computer. I know the virus is there because I had the very same issue a few months ago when I noticed my computer started acting up and it wouldn't let me finish the windows defender scan. 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.
