One other route towards finding out whether a given file is on the radar
screens of the various vendors is to submit it to:
http://www.virustotal.com
http://virusscan.jotti.org
See the browse windows in the upper right of these pages for submission.
This will give you a quick reading about whether the top antivirus vendors,
a few of which are also starting to handle spyware--recognize your critter.
If you are lucky, it'll give you a good enough name to be able to find a
good source of information for manual removal--or perhaps an online scan or
system cleaner capable of doing the job.
Microsoft does not have a public address for submission of binaries.
However, some of the MVP's who frequent these groups do have ways of getting
binaries to the right hands--so if you've got something you are reasonably
certain is "dirty", but seems to be too new to be on anyone's list, speaking
up here is probably the right thing to do.
