Hello BP crew!

Ok, here's my situation:

I'm running Symantec Endpoint Protection on a Windows XP sp 3 System.

4tPkxoQn.exe is a process that keeps starting and it then launches internet explorer, which usually won't even pop up as a window when it does this, it just seems to run in the background...I'll suddenly hear "YOU've won a new X-BOX, or two free ipod nanos" or whatever, and hear mouseclicks and other random sounds.

So I terminate the process tree 4tPkxoQn.exe, which kills iexplore also. I've cleaned out all my temp files with ATF cleaner, ran Ad-aware, Spybot S&D, Malwarebytes, and Symantec Endpoint. They always find the 4tPkxoQn.exe in the Windows/system32 folder and quarantine it, and sometimes other programs/malware/cookies and stuff it has downloaded or regenerated. I delete the files successfully, reboot, and the process starts over almost instantaneously.


I don't even use explorer, or I'd uninstall it, but my fiancee uses it and a remote desktop program to access files at her work.

I've updated all my virus definition files and updates for all the virus/malware programs before I ran them...I've ran the full scans and quick scans with each, multiple times, and get the same results. I'm lost!

Any direction would be greatly appreciated!

Hello and welcome to Bleeping Computer.

My name is km2357 and I will be helping you to remove any infection(s) that you may have.

I will be giving you a series of instructions that need to be followed in the order in which I give them to you.

If for any reason you do not understand an instruction or are just unsure then please do not guess, simply post back with your questions/concerns and we will go through it again.

Please do not start another thread or topic, I will assist you at this thread until we solve your problems.

Lastly the fix may take several attempts and my replies may take some time but I will stick with it if you do the same.

Sorry for the delay in replying, the forum is very busy. If you still need help, please post a fresh HiJackThis Log and an Uninstall List (instructions forthcoming)

Step # 1: Make an uninstall list using HijackThis
To access the Uninstall Manager you would do the following:

1. Start HijackThis
2. Click on the Config button
3. Click on the Misc Tools button
4. Click on the Open Uninstall Manager button.
5. Click on the Save list... button and specify where you would like to save this file. When you press Save button a notepad will open with the contents of that file. Simply copy and paste the contents of that notepad here on your next reply.
