Allows too much malware onto PC
Don't count on this to catch much. My wife who is very much a safe web surfer got 10 pieces of malware on her Windows 7 PC and MSE caught none of it. Not even with a scan. 9 of the malware were Trojans that were not recent creations so MSE should have had definitions to catch them. I finally used Malwarebytes which detected them and deleted them. Very disappointed in Microsoft created such a lousy product. I'll bet plenty of people have malware and rootkits on their PC and don't even know it. Don't trust MSE, scan with another AV product. If Microsoft cannot do any better then this they need to stop giving users a false sense of security with MSE.
