I have a Windows XP (SP2) user who picked up some malware last weekend during a browsing session with IE7. He is now reporting popups, redirects, and overall degraded system performance.

We've taken some steps to remove the malware that I was able to find, but my ability in this sphere is lacking. I have seen evidence of vundo and purity scan, and I have a suspicion that there are others..

I have current HJT and MalwareBytes scan logs, and I would be glad to answer any questions you have for me. MalwareBytes no longer detects any issues, but I still have doubts.. If you have the time, please lend me a hand. Thanks in advance!

Hi, Welcome to TSG!!


Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system. Please follow these steps to remove older version of Java components and upgrade the application. Beware it is NOT supported for use in 9x or ME and probably will not install in those systems

Upgrading Java:
  • Download the latest version of Java Runtime Environment (JRE) 6 Update 7.
  • Scroll down to where it says "The J2SE Runtime Environment (JRE) allows end-users to run Java applications".
  • Click the "Download" button to the right.
  • Select your Platform and check the box that says: "I agree to the Java SE Runtime Environment 6 License Agreement.".
  • Click on Continue.
  • Click on the link to download Windows Offline Installation (jre-6u7-windows-i586-p.exe) and save it to your desktop. Do NOT use the Sun Download Manager..
  • Close any programs you may have running - especially your web browser.
  • Go to Start > Control Panel, double-click on Add/Remove programs and remove all older versions of Java.
  • Check any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button.
  • Repeat as many times as necessary to remove each Java version.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on the download to install the newest version.

The log looks fine.

What have you disabled with MSConfig?

Thanks for getting back to me - I appreciate the help!

I used MSconfig to disable GetModule23.exe, GetPack21.exe, and VNRBlock21.exe (as one step of the cleaning process).

Also present in MSconfig was an entry called 'fourxwsl.dll' which is currently unidentified. Google comes back with no hits for it as a search term. When this entry is enabled, Windows throws an application error at startup.. when disabled, everything comes up clean. I have it disabled for the user's convenience and peace of mind, but I'd love to find out what it is..

I have one other question for you if you would oblige me - this user has an external HDD that he uses as a backup device at home. The infection was picked up while he was working from home, and he does not remember if he sync'ed with the external drive at any time in the days following the infection. Assuming that only the malware we've named is or was present on his machine, how should I go about cleaning the external drive without opening another vulnerability through which the infection can spread?

Many thanks!

You would have to scan the external drive with an anti-virus program. Accessing the files may cause the virus to spread but scanning should be ok.


Please download ATF Cleaner by Atribune.

  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main choose: Select All
  • Click the Empty Selected button.

Click Exit on the Main menu to close the program.




Please download Malwarebytes Anti-Malware and save it to your desktop. alternate download link 1 alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. (see Note below)
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply with a new hijackthis log.
Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.



Please do an online scan with Kaspersky WebScanner

Many thanks for your help with this issue - unfortunately, the user has been called out of state on business and is uncertain when he will return. If the problem persists, I will tackle it when next I have the opportunity. Please close this thread.

Thanks again!
