Hello,

My Win NT4 Workstation is infected with Backdoor.Win32.Rbot.ayg -- AKA -- W32/Opanki.work!MSo6-040. A file i.exe is placed in winnt\system32 and becomes a running process. I have used Sysinternals.com's ProcessCheck to kill the i.exe process and their Autoruns utility to remove keys. It keeps recurring. A file system32\CTFMON.exe seems to be part of the virus package - contains strings "Mutex". After 4 days of work it is still here - ouch! RASMAN.exe seemed to be part of it also. I have temporarily renamed the both ctfmon and rasman. After renaming ctfmon I am having some performance issues.

Kaspersky recognizes i.exe as Backdoor.Win32.Rbot.ayg but does no cleaning. Nod32 does not see it (running on my system). AVG does not see it. Trojan hunter does not. Cleanup.exe installs but will not run with a procedure entry point error for CreateToolHelp32Snapshot. Many of the others recommended do not do NT4. Also ran Bitdefender and others.

My HiJack this log is below.

Any help would be appreciated! - Eric
