PC cannot boot properly due to corrupted critical boot file

Hey,

I’m running the latest Windows Insider Preview build as of today (15014) and am having a bit of trouble with Avast.
After asking for a reboot, the PC couldn’t boot anymore.

Reason found after a quick Startup Repair from the Troubleshooter : Boot critical file d:\windows\system32\drivers\aswbidsha.sys is corrupt.

Tried uninstalling avast, reinstalling it and even using an .iso to reinstall the system (not a clean install), nothing has changed.
I can still boot by Disabling driver signature enforcement on boot but I don’t see it as a definitive solution.

Could any of you guys help me ?

Thanks very much,
URoulon

You can’t expect any software to work properly on a Insider build of Windows.
Contact MS and tell them to have a look and fix things.
