It's actually more useful to post links if you've been obtaining help elsewhere to establish past activity. The IP you posted at computertechs.com points to an EFnet server. EFnet is a very big IRC network - it points to one of their servers, efnet.xs4all.nl. Why it would do this I have no idea - it could well be that you're infected.
Many anti-virus/trojan resources can be found in
this thread. I would highly recommend using two or so virus scanners and two or so trojan scanners as they scan in slightly different ways. From my own Google search of this process there was a mention of a trojan.
As a note on a comment I saw from you on that forum, IRC means Internet Relay Chat - It's a chat protocol. mIRC is a popular program which allows people to connect to IRC. No, it is not a file sharing program
- Unfortunately, many trojans make use of mIRC to connect their 'drones' to IRC networks where they can then be controlled by someone to attack servers, users or websites. Those drones are connected by infected users - you may be one of those.
I have no experience with hijackthis logs, however, for the benefit of other people who may wish to help, this persons logs may be found in
this thread.
Have you downloaded anything or gone to any unusual websites since you noticed this appearing? Anything in the past few weeks/days?
Regards,
