Trojan.zonebac HELP!!!

[shaolin77]

Sorry if this is not in correct forum..but just wondering if anyone would be able to assist with an issue I'm having to deal with. I have an end user who was infected with Zonebac trojan. For more info on Zonebac please click on the following link:

http://www.symantec.com/security_response/writeup.jsp?docid=2006-091612-5500-99

I have attempted to clean out in safemode, but upon rebooting in normal mode....Norton goes off indicating Zonebac infection. This trojan is pretty trick...it make copies of legit exe files and recopies its self as multiple variants....having a hard time identifying which exe file its origniating two. I have already checked for lasss.exe according to the removal steps within Norton...but its not present in the registry...any help would be greatly appreciated.


Thanks,
