Microsoft in Search of Beta Testers for Next Security Essentials Build
According to Microsoft, the new build will sport a simplified user interface in place of the existing one that's already fairly easy to use. It will also feature a new and improved protection engine with "enhanced detection and cleanup capabilities," enhanced performance to minimize the program's impact on your system, and enhanced protection through automatic malware remediation that will "clean high-impact malware infections automatically, with no required user interaction."
If you're not digging the idea of beta software stopping malware dead in its tracks but are a fan of MSE, Microsoft says it expects to release the new version to the general public by the end of the year.
