unwanted ftp client

Got a machine in today, whenever I try to open a command window (from
Start-programs-accessories or from start-run-cmd or start-run-command),
it runs an ftp client instead.
Had a bit of a wander round the registry but not finding anything yet.
Stinger doesn't find anything, but it's a month old now anyway.
While I await the group's knowledge, I shall try some more av packages
and some spyware removers.
