Looks very similar to the Microsoft Windows Malicious Software Removal Tool. Only difference I can tell is that it's updated more frequently. It's worth noting that it expires after 10 days so the user needs to download a new copy with updated definitions.
For those looking for an English link, it is www . microsoft . com / security / scanner / en-us / default.aspx Please remove the spaces, as I cannot post any links ( I have to have 20 posts)
