Hi
MarkT67,
Have you check the value “Disable TaskMgr” in these following keys below?
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System
HKEY_USERS\.default\Software\Microsoft\Windows\CurrentVersion\Policies\System
If you find it, delete it.
Then we could use the command “sfc /scannow” to repair the system files to check.
If the issue still insists, I suppose the Virus may change some files. I suggest that we could try to use the system restore to get an earlier state.
Hope it will be helpful to you
