It looks like the mystery Trojan is Mini Oblivion by
the Rat Pack.  I have passed the iexplore.exe to
Symantec.

General Description was that
iexplore.exe was placed in c:\winnt\system32
Five registry keys were found
HKEY_LOCAL_MACHINE....Windows\CurrentVersion\Run\Default
Web browser "C:\winnt\system32\iexplore.exe" 
HKEY_LOCAL_MACHINE....Windows\CurrentVersion\RunServices\Default
web browser "C:\winnt\system32\iexplore.exe" 
HKEY_LOCAL_MACHINE....WindowsNT\CurrentVersion\Winlogon\Shell
"explorer.exe iexplore.exe"
HKEY_CURRENT_USER\Software\Microsoft\Windows
NT\CurrentVersion\Windows\Run "iexpIore.exe"
HKEY_CURRENT_USER\Software\Microsoft\Windows
NT\CurrentVersion\Windows\Load "iexpIore.exe"

Thanks for everyone who responded.

Does anyone have information on a IRC Trojan with
the
following characteristics.

Opens IRC channels on 6667 and connects to some IRC
channel on 6668.

It sets a registry key


HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\Default
web browser  =  "c:\winnt\system32\iexplore.exe"

And changes the shell


HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\Shel
l
changes it from "Explorer.exe" to "Explorer.exe
iexplore.exe"

I found a 9 KB file named iexplore.exe in
c:\winnt\system32 and also found the iexplore.exe
process running.
