Hello Spec8472,

I’ve tried a fresh Install with actual Offline Installer AVAST Free.

BOSD (Bad Pool Header) at End of Install - automatic Reboot.
Crash dump file created without verifier.exe.
File-ID: 72FGE
All AVAST Modules are off and can’t be started.

Iactivated “Special Pool” and “Pool Tracking” and reboot.
Crash dump file created.
File-ID: LBFK3
All AVAST Modules are off and can’t be started.

Defender is working.
