Since this last patch Tuesday (could be coincidental though), I have a Windows Security Alert showing. Opening the alert it says my Virus protection is turned off. In fact it says 'Microsoft Security Essentials Prerelease reports that it is turned off'. Nothing I can do turns it on again. Which is more than a lttle odd, because my virus protection is indeed Microsoft Security essentials pre-release, and that says my PC is protected, the real-time protection is on, and the virus and spyware definitions are up-to-date. I ran a quick check as well, just in case it was actually drawing attention to the fact that I don't allow it to schedule a check at 2am. This PC is XPsp3 professional. I also have another PC with win 7 pro SP1 that is also running MSE prerelease and that shows no problems at all. Clearly, somebody at MS is off their chump (again). Anybody else seen this one?
