Could you fix the host file first using the download on this page https://support.microsoft.com/en-gb/kb/972034

Also did you set the group restrictions ?

The group restrictions are from our company...the hosts file has been fixed.

OK could you run a fresh scan please as I believe the host file was blocking FRST fixing

Are these the GPO's you are referring to?

HKLM Group Policy restriction on software: %appdata%\*.exe <====== ATTENTION
HKLM Group Policy restriction on software: %appdata%\Microsoft\Windows\Start Menu\Programs\Startup\*.exe <====== ATTENTION

Those were set from Bitdefender's anti ransomware/bitlocker protection I believe.  The only reason I say this is because those two files are listed in the protection options of the software.  Note: I disabled this software long before I posted here with the problems...

Ok, that seemed to work this time...booted up fine, and now I am rebooting again to give it a solid reboot cycle before delving into the next phase, which, I assume is, reinstalling Avast correct?

Yep that is it

Download Avast Uninstall Utility to your Desktop.
Download the correct version of Avast 
Avast Free
Avast Pro
Avast Internet Security
Avast Premier
Disconnect from the net
Uninstall Avast via control panel

  • Run the uninstall tool and accept the reboot to safe mode
  • Once complete reboot your system
  • Reinstall Avast

Tried using Revo and it LOOKED like it was going to actually do it....but after 3 hours of just spinning away, the hard drive pulses every second, and the screen is black....locked up.
Should I do another "FRST" and post to see if anything has changed?

I'm trying to use Revo again - thistime I have "unchecked" the "Use Built In Uninstaller" to see what it does/finds... 

By the way, in case I didn't mention it before - thanks so much for your help on this....

Well it looks like we may be in business...that Revo program is pretty slick and it hunted down the remnants (one of which I am certain was causing the hang of course).   I am currently reinstalling Avast now that I CAN reinstall it...
