Like others Iíve been infected with TrojanDownloader:Win32/Tracur.Y. Iíve Windows XP and have used Malwarebytes and MSE, but the Trojan keeps recurring. Iíve downloaded ComboFix and Rkill, but as suggested, Iíve posted to this forum before using them.

Please advise to the next step.

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.

    Posted Image
  • 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 be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

IMPORTANT! If for some reason GMER refuses to run, try again.
If it still fails, try to UN-check "Devices" in right pane.
If still no joy, try to run it from Safe Mode.

  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download and unzip them from here: http://www.superantispyware.com/definitions.html.)
  • Close SUPERAntiSpyware.
Restart computer in Safe Mode.
To enter Safe Mode, restart computer, and keep tapping F8 key, until menu appears; pick Safe Mode; you'll see "Safe Mode" in all four corners of your screen

  • Open SUPERAntiSpyware.

  • Click the "Close" button to leave the control center screen.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.

The SUPERAntiSpyware log showed everything clean but its under administrator so I can't get to it. OR should I have done this under my user name.?

When I rebooted into normal mode the Trojan reappeared. MSE caught it and I followed up with MBAM.
