Anybody familiar with a folder that appears in the Program\Common Files directory called Wintools? Ad-Aware's Ad-Watch tells me it contains evil stuff and lists the offending files: wtoolsa.exe, wtoolss.exe, wsup.exe and a few others - all of which do appear in the Wintools folder. Ad-Watch can't seem to handle blocking them, however, so I tried to manually delete the files individually and also the entire folder - but I get the red message saying they can't be deleted because they're being used by some other application (I'm thinking somehow it's getting itself online even though I don't have IE open, but I do have a cable connection, so essentially at their mercy?)

Any ideas?
