Re: maybe a simple problem

Another thing you might try, since it's a win98 machine that was hacked and 
*all* the developed trojans I've heard of that would work on win98 either 
use TCP or UDP, would be a simple port scan. Port scan TCP, port scan UDP, 
make sure *every single port* is checked. When a high port shows up that is 
suspicious you may have nailed your problem right there. You may even get 
lucky if the offenders haven't changed the default port and your port 
scanner (like nmap) would be able to tell you which trojan it is right 
then/there.

would be:
*1.  SubSeven
2. Back Orifice
3. Master's Paradise

Keep in mind though, if you find one there's a very good chance there is 
another that was installed as a backup, almost anticipating that one be 
discovered.

Good luck --Michael
