Two things you may wish to try. Run in safe mode & do your scans & see what that finds.
There is a program called RKill that attempts to terminate known malware processes so they can be removed. Some malware will not be deleted if it is running in the background. After running RKill, do NOT reboot.
As RKill only terminates a program's running process, and does not delete any files, after running it you should not reboot your computer as any malware processes that are configured to start automatically will just be started again. Instead, after running RKill you should immediately scan your computer using some sort of anti-malware or anti-virus program so that the infections can be properly removed.
