Error opening site: HRESULT:0x80041051

Received this error in QA after stopping the Forefront services.
According to this post it states to run:http://social.technet.microsoft.com/Forums/en-US/forefrontSharePoint/thread/3f20ae34-03ba-4da0-af20-2b6cfa61663b/

SELECT *
FROM Docs
WHERE (VirusStatus > 0) AND (VirusStatus IS NOT NULL)

You should get results. Then run:
Update dbo.allDocs Set VirusVendorID=NULL, VirusStatus=NULL, VirusInfo=NULLwhere (VirusStatus > 0) AND (VirusStatus IS NOT NULL)

Sites should be accessible. But we had issues still. So I had to start the Forefront services and stop it from within Forefront by disabling manual scan and bypassing realtime scan. Then ran the queries again and all sites were functional.

So I followed this by opening up the metabase.xml file located in windows\system32\inetsrv and removing these lines:

Once this was done everything was working normally.
