Avast Free wont start

System without antivirus. Got the Windows Active Guard malware.
Ive got the virus removed and all of it ugly tendrils I could find. No sign of it now. I was able to run Spybot Search & Destroy and its all clear now.
But now I tried to install Avast and it installs but wont run. I get an hour glass for a split second and nothin’.
I tried unistalling it with Control Panel and it did nothing. I downloaded the uninstall utility and It did finally uninstall. I reinstalled Avast and it still wont launch. Also I cant get Task Manager to come up with Ctrl-Alt-Del either.

Does anyone have any idea what has been damaged?

Thanks.

Possible still infected…and malware is blocking maybe

Could also be interference from Tea Timer which is part of Spybot S&D. ???

Not Tea Timer…
This has really got me stumped.
Anyone else has any inkling what this is?? … anyone??, Anyone?, Beuler?
