XP SP3 laptop running zonealarm and avira antivir personal is infected with TR Vundo/Gen and Migotrup.gen.xxx Trojans. In addition, a "logon.exe" cannot be found message seems to pop up quite frequently. Have tried a few procedures in order to get rid of the infection myself, but have not been successful - VundoFix, Avira etc.

Can you help? Please suggest a course of action. Thanks in advance.

Please download Malwarebytes Anti-Malware (v1.41) and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on 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 definition 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.
  • 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

-- If Malwarebytes Anti-Malware results in any error messages, check the Help file's list of error codes within its program folder first. If you do not find any information, please refer to Common Issues, Questions, and their Solutions, Frequently Asked Questions. If the error you are receiving is not in the list, please report it here so the research team can investigate.

-- Some types of malware will disable Malwarebytes Anti-Malware and other security tools to keep them from running properly. If MBAM will not install, try renaming it first.
  • Right-click on the mbam-setup.exe file file and rename it to mysetup.exe. If that did not work, rename it explorer.exe.
  • Double-click on the renamed file to start the installation.
  • If that still did not work, then try changing the file extension. <- click this link if you do not see the file extension
    If using Windows Vista, refer to these instructions.
  • Right-click on explorer.exe and change the .exe extension to .scr, .com, .pif, or .bat.
  • Then double-click on explorer.com (or whatever extension you renamed it) to begin installation.
If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe and rename it to wuauclt.exe.
  • Double-click on wuauclt.exe to launch the program.
  • If that did not work, then change the .exe extension in the same way as noted above.
  • Double-click on wuauclt.com (or whatever extension you renamed it) to launch the program.
Note: If installation coninues to fail in normal mode, try installing and performing a Quick Scan in "safe mode". Doing this is usually not advised as MBAM is designed to be at full power when running in normal mode and loses some effectiveness for detection & removal when used in safe mode. Further, scanning in safe mode prevents some types of malware from running so it may be missed during the detection process. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM. Therefore, after completing a safe mode scan, reboot normally, uninstall MBAM, then reinstall it and perform another Quick Scan.

Now rescan again with Malwarebytes Anti-Malware, but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for database definition updates through the program's interface (preferable method) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Please download the Kaspersky Virus Removal Tool save to your Desktop.
Be sure to print out and read the instructions provided in How to use Kaspersky virus removal tool.
  • Double-click the setup file (i.e. setup_7.0.0.290_24.06.2009_12-58.exe) to install the utility.
  • If using Vista, right-click on it and Run As Administrator.
    If you receive a UAC prompt asking if you would like to continue running the program, you should press the Continue button.
    .
  • Click Next to continue.
  • It will install by default to your desktop folder. Click Next.
  • Click Ok at the prompt for scanning in Safe Mode if you booted into safe mode.
  • A box will open with a tab that says Automatic scan.
  • Under Automatic scan make sure these are checked.
  • System Memory
  • Startup Objects
  • Disk Boot Sectors
  • My Computer
  • Any other drives (except CD-ROM drives)
  • Click on the Scan button.
  • If malware is detected, place a checkmark in the Apply to all box, and click the Delete button (or Disinfect if the button is active).
  • After the scan finishes, if any threats are left unneutralized in the Scan window (Red exclamation point), click the Neutralize all button.
  • In the window that opens, place a checkmark in the Apply to all box, and click the Delete button (or Disinfect if the button is active).
  • If advised that a special disinfection procedure is required which demands system reboot, click the Ok button to close the window.
  • In the Scan window click the Reports button, name the report AVPT.txt and select Save to file.
  • This tool should uninstall when you close it so please save the report log before closing.
  • When done, close the Kaspersky Virus Removal Tool.
  • You will be prompted if you want to uninstall the program. Click Yes.
  • You will then be prompted that to complete the uninstallation, the computer must be restarted. Select Yes to restart the system.
  • Copy and paste only the first part of the report (Detected) in your next reply. Do not include the longer list marked Events.
If you cannot run the Kaspersky AVP Removal Tool in normal mode, then try using it in "safe mode".

Quietman7, I just got done with running the Kaspersky Virus Removal Tool scan. It did not find anything.

However, the tool did not seem to kick out a report in a behavior that you had mentioned in your instruction.
We did see a report; but it was not in plain text. I do have a screenshot of it and can forward it by email if you wish. Thank you for your help.

Upload it to an image site such as Photobucket, Media Fire, TinyPic or ImageShack and provide a link to the url address back here?

I don't see any threats detected/removed. That means it was a clean scan (all malware already removed) or it failed to find anything else. How is your computer running now? Are there any more reports/alerts, signs of infection or issues with your browser?

Quietman7 - Computer seems to be running well. The sound card drivers and the wireless card drivers got corrupted during this event. I am in the process of reinstalling them. I will watch the machine for another day and then send you my comments within 24 hours. This has been a great experience! Thank you for your help.

You're welcome.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Posted Image > Run... and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.

Quietman7 - The machine seems stable this am. I have implemented your suggestion on the Restore Point. Thank You.

In order to avoid future similar issues, what do you recommend in terms of monitoring applications? Currently, I have ZoneAlarm and Avira AntiVir running on that machine. Is that enough? FYI, I recently migrated from AVG to AntiVir. Please advise at your convenience. Thanks.
