I have been having problems with MS Security Essentials Anti-Virus. When the computer starts up i notice it to be very slow, i cannot access network links and i notice that the network icon does not load until i end "MsMpEng.exe" which i know is related to MSE. I have seen this on numerous client computers running XP & Win7 at different locations. I have down malware scan and spyware scans and all is clean. I have taken off this AV in the meantime until it gets fixed (re-installing MSE does not help). I just want to know if anyone have come across this before and is there a fix/workaround? I am guessing windows has done some updates or MSE Has done a faulty update to cause this.
