Uninstalled cryptoprevent.   NO JOY,   Installation completed but windows would not start on reboot.   Repaired using restore point.
Befor uninstallin Cryptoprevent, did you run it and remove the protection ??? (Removing the protection restores the Windows Policy settings. If that wasn't done before it's removal, the changed policy would still be in effect and could still be the problem.

Yes, I restored the policies before uninstalling Cryptoprevent.    That did not work.

I would love to see the final outcome of this problem.
A problem I've never encountered and I've installed Avast on hundreds of computers.
I hope you can finally pin this down. :)

I think the only way to truly know is do CLEAN uninstall of Avast.
Boot into Windows and setup a CLEAN BOOT in MSCONFIG.
http://winaero.com/blog/how-to-perform-a-clean-boot-of-windows-10-to-diagnose-issues/
INSTALL Avast.....I'm assuming will install.
Reboot.....I'm assuming will reboot into Windows.
Go into MSCONFIG and one by one click on items, rebooting after each one, until you find culrpit.

I disabled all non windows services and all startup programs and windows still would not boot after a clean install.   I am going to need to go into auto-runs and see if there are any suspicious programs starting.   Headed out for spring break so problem is on the back burner for a week or so.   Happy Easter everyone.
