AVG caused Windows failed to Start on Windows 7

Not an invention but quicky on what to do if AVG Free, get what you pay for, causes your system to be unable to reboot.

In my case I had the following:

Windows failed to start. A recent hardware or software change might be the cause.
File: \windows\system32\drivers\avgVmm.sys
Status: 0xc0000098
Info: windows failed to load because a critical system driver is missing, or corrupt.

I found the file, so assuming the issue was corruption or something.
Anyway, the quick fix solution is to navigate to \windows\system32\drivers directory and delete all the avg*.sys files.

Then you should be able to reboot windows, uninstall AVG, and if you want your AVG Free back, reinstall it.

Here are some useful links.

You will probably need to boot from a cd or usb drive to get to a command prompt to delete the files. I used AVG Recover and went into the File Commander under utilities (or something like that, forgot the name).
