VirusScan 8.7 and Security Center reporting

If you've been driven to distraction recently by users who noticed that the Windows Security Center wasn't reporting their McAfee VirusScan 8.7 status correctly, you're in luck. Messages like "McAfee VirusScan Enterprise is on but reporting its status to Windows Security Center in a format that is no longer supported" on Windows 7 and Vista, while only a reporting issue, were resulting in a lot of questions.

McAfee has released Patch 2 (link goes to the readme) for VirusScan 8.7 which fixes the issue. Along they way, they also improved the performance of On Access scans, which many users were complaining about as well.

What went wrong? Well, the Microsoft API for this reporting was updated, and this required updates from vendors. McAfee's patch lagged behind, resulting in worried customers. The good news is that their AV was working. The bad news is that we've spent years making our customers more aware, and now even a false positive can cause a lot of helpdesk calls.
