According to Windows enthusiast site Neowin, the anti-spyware tool is code-named "Atlanta" and is an exact replica of the Giant Software product that was acquired by Microsoft last month.

"As we stated when we acquired Giant Company Software on December 16, we planned to issue a public beta of an anti-spyware solution within the month. We're still on target to reach that timeframe, but beyond that, we aren't commenting on an exact release date or functionality at this point," the spokesperson added.
