The software giant says that during the first week in circulation, MSE detected malicious software on precisely 535,752 machines -- and the actual malware count is eight times more than that. Microsoft says early adopters of Windows 7 seem to be the most prominent users of MSE, which seems logical enough, and around one third of those systems are running a 64-bit version of Windows 7.
The general consensus seems to be that MSE is a relatively solid product, and with some 4 million malware detections in its first week, Microsoft's antivirus is at the very least helping some users to keep clean.
