Microsoft is about to release a first public beta version of their new free anti-virus software program Morro which is supposed to fill the gap left by the Microsoft One Care demise. Morro seems to be concentrating on being an anti-virus software program without additional modules that allow a user to create backups or use a firewall for extra protection. Those extra modules are on the other hand already available in the Windows 7 operating system which makes Morro the ideal candidate to fill the one layer of protection that is not already shipping with Windows 7: Anti-virus protection.
Microsoft has said "it will provide protection from several types of malicious software including viruses, spyware, rootkits & trojans"
It is not yet clear how Morro will run along with Windows Defender. It basically seems that Morro will be Windows Defender with added capabilities to detect and remove viruses, rootkits and trojans as well as spyware. The anti-virus software is expected to enter public beta stage in the coming months with no exact date given yet.
