What is UDP Port 8998?

and, how do you enable or diable it?

It has something to do with Sobig-F:

"on Friday or Sunday, W32/Sobig-F sends a UDP packet to port 8998 of a remote server. This feature could be used to download and run a Trojan or additional worm components."

"To prevent malicious code from being downloaded by W32/Sobig-F, Sophos strongly recommends that customers consider configuring company firewalls so outgoing connection attempts to UDP port 8998 are blocked."
