You didn't answer my question. Is it running a scan while the MsMpEng.exe is hogging the CPU.
I checked on my moms computer (she runs MSE) and on her P4 2.8 HT it can go as high as 60% when running a scan. What speed is your CPU?
Microsoft Security Essentials Running
MsMpEng.exe-Windows Internet Explorer Running
Task status it is normal for Microsoft Security Essentials if it is not minimized.
Regarding MsMpEng.exe-Windows Internet Explorer...I don't know what that is all about. It should say the website title.... http://localhostr.com/files/ovWQ5ys/taskmanager.png
