Hello,

This morning, I clicked on a search link in Firefox and a program was installed without my consent (didn't catch the name but saw a quick "installing" window on the taskbar). Afterwards, I noticed a new folder named "Help Assistant" in my Documents and Settings folder. Fearing that I had contracted a virus, I ran a scan with Malwarebytes Anti-Malware which found nothing, then ran a scan with Avast! Free Antivirus which found the following infected files:

C:\Documents and Settings\HelpAssistant\Local Settings\Application Data\4125631625.dll (Win32:MalOb-AL [Cryp])
C:\Documents and Settings\HelpAssistant\Local Settings\Temp\CLeK.exe (Win32:Malware-gen)
C:\Documents and Settings\RLG\Local Settings\Application Data\4125631625.dll(Win32:MalOb-AL [Cryp])
C:\Documents and Settings\RLG\Local Settings\Temp\CLeK.exe(Win32:Malware-gen)

Thinking that the virus had been removed, I then tried to delete the entire "Help Assistant" folder, but it was huge (computer estimated it would take 45 min) and the computer gave me warnings that deleting some files would lead to programs not operating, so I canceled and just renamed it. After rebooting, I had another "Help Assistant" folder and had the same problems deleting that one. The folder contains many of the same files as my "RLG" user folder, almost like a copy of it. I checked in User Accounts and don't see a "Help Assistant" listed.

My computer does seem a bit slower, and when I ran ComboFix.exe, it confirmed that a rootkit was running (but did not say which one). I'm not sure how extensive the problem is, as this problem just started happening a few hours ago and I haven't done anything except the things necessary to prepare this post. I am hoping someone can help me figure out what's wrong and why this folder keeps appearing.

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below another staff member will review and take the steps necessary with you to get your machine back in working order clean and free of malware.

If you have already posted a DDS log, please do so again, as your situation may have changed.
Use the 'Add Reply' and add the new log to this thread.


Thanks and again sorry for the delay.

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE



Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.


  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.
regards,
schrauber
