My PC wont boot after AVG Antivirus update and auto restart

My PC won't start after AVG update and auto restart.

"
RECOVERY

The operating system couldn't be loaded because the digital signature of a file couldn't be verified.

File\Windows\system32\DRIVERS\avgmfx64.sys
Error code: 0xc0000428

You'll need to use recovery tools. If you don't have any installation media (like a disc or USB device), contact your PC administrator or PC/Device manufacturer"

i'm really pissed off because an Antivirus software f@cks up my computer.
i hope you can help me because it has really important data on this PC 
I can make a bootable USB device with Win 10 but will i use any data?

I had this same problem and was able to fix it without reinstalling windows.  To boot up around the error, click on F8 during that initial message and click disable signature verification (7).  It should boot normally.  I did a full scan and found a virus which I removed.  Removing it didn't fix the problem but an uninstall and reinstall of AVG did.  A 'repair' of AVG did not fix the problem.

Hi Trung.
Please accept my apologies with regards to the AVG software not living up to your expectations.

Imagine claiming to be a reputable anti-virus provider yet continuously getting told about a problem your answer is always "Uninstall and reinstall" or "It's not our product."

 

I just did a complete reimage on my computer, taking things step by step, and low and behold AVG Internet Security is what is causing an issue on boot up. Y'alls product is broken and your failure to fix the problem after at least five years of versions is a terrible business practice. I switched over from Avast because of these issues, only to find that the reason both these programs have these issues is that they are the same program under different names run by the same bullshit company.

Having exactly the same problem in Win7. Tried running in safe Mode and any other combinaton but no luck. Gets as far as loading avgbidshx.sys and then reboots.

All your llinks above assume that you can boot into Windows. I can't!

No use telling me to remove AVG because the PC DOESN'T BOOT!!! I can however access the drive from another PC. I've tried renaming the AVG folder but it's loading the files from C:\windows\system32\drivers. So I removed the AVG files from the drivers folder - AND it still finds them???

So now I have a brick, courtesy of AVG.

So how do I manually remove AVG from the harddisk - including the registry, and any drivers that it's managed to scattered around.
