all of my Anti virus and internet security programs.
Windows defender is also affected (will not remain on when I turn it on). After I realized that my internet security and antivirus programs had been deleted, I turned on Windows defender and ran a scan
(that took 10 hours!), but windows defender will not remain in the on state when I shutdown my computer and restart it.
Since then, I have re-installed my internet security and anti-virus.

I don't know how they got locked or how to unlock them! Anyone on that issue? I suspect my windows installer program is corrupt, since that is where the whole mess started.
How can I remove my present windows installer and replace it with a genuine windows
