First I want to say I'm sorry that you weren't able to eliminate this back in January:http://www.bleepingcomputer.com/forums/ind...wtopic=7934&hl=
To answer your question, I have personally not ever had this infection but have run across it before in HJT logs. It's from the 2nd Thought Adware trojan and sorry again, but I, we, run across so many of these things when doing logs, I can't remember exactly what it takes to get rid of it. I do seem to remember that it was difficult.
What I suggest is that you start the malware removal process over again by posting another HJT log. There is a new version since you last posted so first update HijackThis by following the instructions in this post:How to post a HijackThis Log
Before posting a log, tho, you should do the preliminaries, an important part of which is running AdAware and Spybot in Safe Mode as jgweed has suggested. In your case it is much more effective to run these programs in Safe Mode and I would run a full system scan with your antivirus (still Norton?) in safe mode as well.
That may eliminate it, but whether it does or not I would still post a HijackThis log.
I also noticed in your old log that you were running an unpatched XP. If you are still doing that you will continue to get infected thru security holes despite all the security apps you have installed. So it is important that you do this:
1. With Internet Explorer Open, click on Tools, Windows Update.
2. Let it scan and then choose Custom Installation.
3. Put a checkmark next to only Windows Malicious Software Removal Tool
and allow that to run. It should rid you of any malware on your PC that got installed thru the vulnerabilities of an unpatched system. Like the l?ass.exe file you had problems with.
4. When that is done, exit Windows Updates. Open this link to the Windows XP Service Pack 1a
page, select Express Installation and follow the instructions to download/install Service Pack 1a (SP1a). Reboot when requested. Hold off on SP2 for now.
After you have been given the all clear and are comfortable that all is working as it should, then I recommend you go ahead and install SP2. As SP2 is a large update, you may want to order the CD from Microsoft instead of downloading the file. Order here.
Then return to Windows Update
and install any remaining Critical Updates.
