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.
