Send a suspected spyware report from the tools menu.
Restart the computer in safe mode, on the scan page, choose Scan Options >
Full System Scan (check boxes below) > click "Run Scan Now".
This feature is not broken on all installs.
It is broken on a large number, I'm afraid. but it really does work.
Additionally--on those systems where it does work, because of the current
movement of stuff from Spynet.com to Microsoft.com, the facility to see your
report in final form is broken as well--so even if you get a successful
submission, as I do, you can't see the report in easily readable form, which
is too bad.
