Microsoft Security Essentials Beta no longer available

On Tuesday, 22 Jun 2009, Microsoft released a beta version of its upcoming free anti-virus product, code named Morro. When I checked the site this morning (24 Jun 2009), the download link had been removed and the following Alert was posted:

Thank you for your interest in joining the Microsoft Security Essentials Beta. We are not accepting additional participants at this time. Please check back at later a date for possible additional availability.

Too bad. My main desire was to test the AV client out on some virtual machines that are running server OSes like 2003 and 2008, which I later learned aren’t supported by Microsoft Security Essentials yet anyway.

If MSE is effective and remains free, I will be likely to discontinue buying third-party anti-virus clients from Symantec, MacAfee, and the like.
