Hi, I have a problem. The Norton Anti Virus found intmon.exe trojan and I can't find cleaning instructions for it. I ran HJT after Norton quarantined the file. Here is the log.
Thank you for looking in to this.

I don't see anything in your log, except a bunch of toolbars in the O3 area, which I would get rid of.

Download ewido, if you haven't tried it yet.

You can download a trial version of Ewido here: http://www.ewido.net/en/

Be sure you update it before using it, and when it finds a problem, be sure to select the check box to do the same action (clean) when it finds a problem, otherwise, you will have to click continue, to keep scanning with every problem it finds.

Hi, yes I could not see it either in the log. Must be because it is in quarantine. The computer runs normal again too. Before the quarantine I kept getting low memory warnings and the computer was very slow and locked up. Now my question is: is it all right to leave the Trojan in quarantine or do I still have to clean it?? I did not run ewido jet.

You can leave it in Quarantine, but I would delete it. You may have your system files hidden and that may be why you didn't see it. You can go to My Computer/Tools/Folder Options/View Tab, and then click on the tick mark for show hidden files and folders
