All these security offerings from MS are getting confusing. This used to be Anti-Spyware Beta 1 and was bought from Giant a few years ago. I have been running this for a while on my Windows 2003 machine, but found that it didn't pick up some things that the free MS virus scanner did.

As OneCare isn't available for Win 2003 I will continue to use Defender with frequent online scans until I get my hands on Microsoft Client protection - I have signed up for the beta.
