Microsoft Security Essentials enjoys warm reception in first week

I'm a huge fan of Security Essentials (and Windows 7, and a number of other MS products, but I digress). It's quickly become my recommended free antivirus app of choice and protects all three of the laptops in my house. And I've got plenty of company.

The Microsoft Malware Protection Center blog has posted some interesting numbers. After its first week, Security Essentials has already been installed more than 1.5 million times. From the approximately 535,000 machines reporting statistics, MSE has logged over 4 million detections.

44% of MSE users are already running Windows 7 with XP following at 33% and the remaining 23% on Vista. The number of detections per OS is also interesting. 52% of the 4 million reported were found on Windows XP systems compared to only 32% on Vista.

Windows 7 users fared even better. Though they represent the largest group of MSE users, only 16% of detections came from systems running Microsoft's latest OS. The post also reports 1/3 of these machines are using the 64-bit version, which "is even more resistant to malware than 32-bit due to PatchGuard," states Microsoft's Joe Faulhaber.

Security Essentials is a free download, and is available directly from Microsoft.
