TrojanHunter reports the following on my Daughter's laptop:~

Found trojan file: C:\WINDOWS\SoftwareDistribution\Download\b26221300b8d38ab88cee63144c1c81362bed3b6/ssdevm.dll (Generic.Vundo.C)

TrojanHunter is unable to remove the infection, and when I search for it I cannot find it, but TrojanHunter reports it again when I re-scan.

Any suggestions on how I can remove this infection?

Thanks in advance.

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 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.
  • 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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Is TrojanHunter still reporting a problem?

The detection could be a false positive as the file may be related to Samsung Electronics although the description shows it running from a different folder.

Get a second opinion. Go to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file(s) and submit (upload) it for scanning/analysis.
-- Post back with the results of the file analysis.

Contact TrojanHunter Support and advise them of the scan results. Most security vendors will ask you to send them a sample of the detected file so they can investigate further and correct the issue if it is a FP.
