First of all, you uploaded the wrong file....I asked for logonui.dll, not .exe to be uploaded. No matter at this point.

I can see that Ewido IDd it as PurityScan and slated it for removal on reboot. Please ensure this file has been deleted:

C:\WINDOWS\system32\logonui.dll <<<NOT logonui.exe!!!!!

You have an apparent email worm that's not showing in the HJT log. It is the power of these online scans that help us root it out. There's only so much I can do from here without seeing what it is on the machine that's causing the issue.

You may want to purge your email folders, sent items, deleted items, etc....to help eliminate the possible source.

I also see cracked software on the system, according to Ewido. Cracks are one of the greatest causes of infection.

Have you updated Norton and run a full system scan with it since this occured?

We can use another free standing (offline) scanning tool to help us. You'll need to download it on a clean machine, and carry it to the infected machine.

* Download Dr.Web CureIt to the desktop:
ftp://ftp.drweb.com/pub/drweb/cureit/drweb-cureit.exe

• Doubleclick the drweb-cureit.exe file and Allow to run the express scan
• This will scan the files currently running in memory and when something is found, click the yes button when it asks you if you want to cure it. This is only a short scan.
• Once the short scan has finished, mark the drives that you want to scan.
• Select all drives. A red dot shows which drives have been chosen.
• Click the green arrow at the right, and the scan will start.
• Click 'Yes to all' if it asks if you want to cure/move the file.
• When the scan has finished, look if you can click next icon next to the files found:
• If so, click it and then click the next icon right below and select Move incurable as you'll see in next image:
  
  This will move it to the %userprofile%\DoctorWeb\quarantaine-folder if it can't be cured. (this in case if we need samples)
• After selecting, in the Dr.Web CureIt menu on top, click file and choose save report list
• Save the report to your desktop. The report will be called DrWeb.csv
• Close Dr.Web Cureit.
• Reboot your computer!! Because it could be possible that files in use will be moved/deleted during reboot.
• After reboot, post the contents of the log from Dr.Web you saved previously in your next reply.

Also do this:


Right click on http://www.silentrunners.org/Silent%20Runners.vbs and choose Save As...Save it to your Desktop. Make sure you have disabled any programs that may block/disable scripts (ex: Ad-Watch, TeaTimer, Norton, etc.). Double click on 'Silent Runners' to run it. This will take a few minutes. It will create a file called 'Startup Programs' followed by your computer name and current date. Open up that file and post all the contents here in your next post.
