The good news is that your IP address is not listed in any of the more
popular DNSBLs, not even SpamCop. However, MSOE normally doesn't send
email on its own. The kind of problem you describe is usually the result
of infection by a spamming Trojan. AV programs are not always good as
spotting Trojans. You do need to make a thorough analysis of your
computers. See if running 'netstat -a' shows anything, or get TCPView
from Sysinternals (http://www.sysinternals.com/).

If you have a wireless network, you need to use WPA encryption, or
better. While it isn't common, it has been done; spamming through
somebody's insecure wireless LAN.

There is an outside possibility that your ISP is mistaken. But don't
just assume that is so. You've got to check your equipment. Twice. Make
_certain_ it is clean before assuming that the ISP is wrong.

I just ran your posting IP address against my MTA logs. No matches for
the last three, or four months. I do see Shawcable IP addresses in those
logs from time to time, though.
