Unknown program

I have a program running on my computer that appears on my firewall but I think it may be an intruder. It is called HTJJ.exe and will not allow itself to be de-activated or deleted. Any ideas?
Thanks

 

Thanks, I did that but it only tells me that it was created last November, not a time when I was installing anything new, and that it's in C;\WINDOWS\SYSTEM ........ leaves me none the wiser, and it doesnt appear to be on either of my other p.c.s

 

Old_Git--Are you sure about the name of that file? Neither Yahoo nor Google had anything on HTJJ.exe.

 

I take it that you have run a virus scan? Some trojans, such as Subseven, do use random names (hence the reason for no Google hits?).

 

I found this:

Perhaps you have some malware try to use your computer to propagate spam. Run Spybot and see what gives.

Then do a full AV and Trojan scan using some on-line program since your may be subject to duping by this bug.

You can also boot to a dos session and delete the critter but I would suggest that you merely rename it (htjj.old) in case it's actually a good guy. This method may cause an error upon boot but that will have some info as to whats calling this executable.

Also look in msconfig to see if it's listed in start-ups.

 

Thanks
