I threw up this rule to catch Sobig.f trying to access its bots for 
downloads.  You might also want to block 8998/UDP at your edge:

# This rule should catch Sobig.f infected clients
alert udp $HOME_NET any -> any 8998 (msg: "ALERT!!! Sobig.f infection!!"; 
classtype:trojan-activity; sid: 10000009; rev: 1;)
