I have been running the Reliability and performance tool  and  I am also running Vista home Prem with MSE installed. I keep getting this :  The Security Center has reported that on-access spyware scanning  is disabled. Either on-access scanning is disabled, or  the anti-spyware application is not recognized.  MSE has everything updated  and is working  as it should be. Any help here or is it due to the layering  of windows defender on top of MSE that causes the conflict?
