Well, AOL forced me to uninstall the version of McAfee that I PAYED for and replaced it with a free version that barely even works. I disabled the AOL firewall and re-enabled the Microsoft firewall. I also followed the instructions in something that you linked to. Is there any way to tell which firewalls are running?

EDIT: Could you look at a Hijack This log?
EDIT:: For some reason, the IP addresses for the two Gnutella services keep changing to my computer name. Is that what' causing the problem?
