This trojan called Agent.VN is infecting my computer. I've tried STOPzilla, Spybot search and destroy, and VundoFix. Stopzilla says it deleted the registry key for it, but it keeps coming up on the scan. can't get rid of it. Any pointers?

Sunbelt classifies Agent.vn as Rootkit.Agent.VN. Its hard to tell if this is the same vendor specific name and file as given by STOPzilla.

I recommend performing a scan with Sophos Anti-rootkit or Panda AntiRootkit.
Before performing a scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
  • Disconnect from the Internet or physically unplug you Internet cable connection.
  • Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
  • Temporarily disable your anti-virus and real-time anti-spyware protection. (Re-enable when done)
  • After starting the scan, DO NOT not use the computer until the scan has completed.
Note: Not all hidden components detected by ARKs are malicious. It is normal for a Firewall, some Anti-virus and Anti-malware software (ProcessGuard, Prevx1, AVG AS), sandboxes, virtual machines and Host based Intrusion Prevention Systems (HIPS) to hook into the OS kernal/SSDT in order to protect your system. You should not be alarmed if you see any hidden entries created by these software programs after performing a scan.

Then 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. Reagardless 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.

Did the scans find and remove the infection?

Can you post the log results?

Dang, man. I guess I replied to early, because both anti-rootkits couldn't find anything. STOPzilla classifies it as a Trojan. Are you sure we're talking about the same thing? Ha, luckily, Malwarebytes caught 9 infected viruses in the first couple seconds it started to run. I wish somebody could have told meabout this earlier. In e end... 48 viruses removed. Thank you. I don't know how to print out the data though. Could you explain it to me?

Did you reboot the computer after using MBAM? If it encounters a file that is difficult to remove, you need to restart the computer so the malware can be fully removed. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. Your log indicates some files will be deleted on reboot. If you have not rebooted, make sure you do this. When done, rescan again with MBAM and check all items found for removal. Then click the Logs tab and copy/paste the contents of the new report in your next reply. If you did reboot, then rescan again anyway and post a new log.

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 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 Start > Run and type: Cleanmgr
  • Click "Ok".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
