HP Recommended
Product: HP ProBook 470 G2
Operating System: Microsoft Windows 10 (64-bit)

After freshly installing Avast Premier on a brand new HP ProBook 470 G2 with Windows 10 Home, I keep on getting the following message that prevents Windows from booting normally:

The operating system couldn't be loaded because the digital signature of a file couldn't be verified. File: \Windows\System32\Drivers\aswVmm.sys Error code: 0xc0000428

The workaround is to pres F8 and 7 - Disable driver signature enforcement in startup options.

Or to disable secure boot in BIOS.

 

I got answer form Avast support, that their driver aswVmm.sys did not have WHQL signature, but nobody had reported the problem so far. 

 

Is secure boot in ProBook 470 G2 UEFI bios somehow more restrictive than other secure boot bioses? Could the missing WHQL signature be the problem? Is there any other workaround?
