yea, I tried all that. Even with malware installed it would not allow me access to it. Everything seems to be back to normal after the restore.
Find the .exe for Malwarebytes, Malwarebytes.exe, or mbam.exe or whatever it's called, and rename it to asdkhiao3948hu.exe and run it.
Many viruses/malware block or prevent the execution of known cleaning tools names, and simply renaming them to something random allows them a first run.
I would still run a raft of tools, because it's quite likely there's malware hiding in various places like the restore point files, and critical system file backups etc.
