okay according to the log, your norton disk doctor is infected,
now since other anti-virus/anti-malware programmes have not been able to disinfect the system, id recommend you uninstall norton disk doctor.
Additionaly, did you not remove all registry entries of Limewire?
delete the infected key
go to
Run>regedit
>HKEY_LOCAL_MACHINE > SOFTWARE>MAGNET>HANDLERS>LIMEWIRE
Delete the following:
C:\Documents and Settings\All Users\Application Data\aol\c_aol 9.0\idb\bart\1024
C:\Documents and Settings\All Users\Application Data\gtek\gtupdate\aupdate\channels\channels.ini
C:\Documents and Settings\All Users\Application Data\symantec\common client\settings.dat
Reboot and please post a new HJT log and MWAV scan
