Port 81 is open on my PIX 501 Firewall

My 501 Pix is Running 7.0(8) code, I have 3 Interfaces nIside DMZ & Outside. When I use an independent System to scan the DMZ and Outside interfaces, the result is that port 81 is open, even though It is not in the access list. I went through the config with a fine tooth comb and it (port 81) is not in any of the access lists. I am puzzled. Cisco PIX and ASA explicitly denies unless it manually opened via an access list. Can some please give me your opinion on this. I need to desperately close this hole, to keep out the unwanted worms and the like from spoiling my days and nights.

Thanks in advance.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
