Microsoft has officially unveiled its long-awaited consumer antivirus offering. Formerly code-named “Morro,” it’s now been christened Microsoft Security Essentials, and it will enter public beta testing next week. If you have a licensed copy of Windows XP (Service Pack 2 or above), Windows Vista, or Windows 7, you’ll be able to download and install the software at no additional charge. No subscription is required for ongoing definition updates, either. The final release is scheduled for this fall.
