The older version of Nmap is strictly a DOS shell run program. No install 
needed. Bot it should be in the tree somewhere. Given the fact that some 
might have planted TROJAN on a machine is now controlling from within I 
would have an Investigation and Vulnerability scan of all the machines done 
ASAP. Test for Trojans and viruses. Find out how Nmap got on ANY box.

Good luck. If you need help I know of some people like my company who 
perform these tests.
