Today, scanning with AVG detected:

File: C:\Windows\System32\Drivers\ao1drgbn.SYS
Result/Infection: Hidden driver

I can't find anything on Google with it.

Was is successfully "healed" or quarantined?

It was successfully "removed." I have no idea what the extent of that file did or would do. However, I was able to restart the computer successfully. At least my OS is intact.

Yeah it is strange when it gets no google hits.

We can try to search within AVG sites.
