Any one out there have any idea how to rid an XP SP2 box of a Trojan named win32/train.A!joke ?
I use the CA eTrust EZ Antivirus software and it consistently shows up this Trojan, with no option to remove it. The error shows the malware to be located in a file A0061154.exe
The CA website assures the reader this is a low threat Trojan, and again offers no suggestions of removal.
Any suggestions appreciated.
Thanks,
CJM

Can you provide the location (full path) of A0061154.exe? Is it in C:\Windows, C:\Windows\system32, a temp folder, System Restore, etc?

The AV program shows the file A0061154.exe to be located at:

\Device\HarddiskDmVolumes\PhysicalDmVolumes\BlockVolume1\System Volume Information\_restore{6CB89035-97F1-44FB-BB78-F469EFB4A301}\RP492\

I ran Cleanmgr, and the latest versions of Ad-aware, Stinger, Spybot SD and my installed AV.
Nothing seems to find it though.

It doesn't seem to be hampering the machine speed, it just pops up once in a while.

BR,
CJM

The files identified by your scan are in the System Volume Information Folder (SVI) which is a part of System Restore - the feature that allows you to set points in time to roll back your computer to a clean working state. This folder is protected by permissions that only allow the system to have access and is hidden by default unless you have reconfigured Windows to show it.

Keep in mind that System Restore will back up the good as well as the bad files so when malware is present on the system it gets included in any restore points. When you scan your system with anti-virus or anti-malware tools, you may receive an alert or notification that a virus was found in the System Volume Information folder (System Restore points) but the anti-virus software was unable to remove it. Since the System Volume Information folder is a protected directory, your tools cannot access it to delete these files and they sometimes can reinfect your system if you accidentally use an old restore point.

To resolve this, you need to Set a New Restore Point to enable your computer to "roll-back" to a clean working state and use Disk Cleanup to remove all but the most recent restore point.

However, before doing this, do the following:

Please download ATF Cleaner by Atribune & save it to your desktop. DO NOT use yet.

Please download and install SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.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 them from here and unzip into the program's folder.)
  • Under "General and Startup", make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Under "Configuration and Preferences", click the Preferences button.
  • Click the Scanning Control tab.
  • Under Scanner Options make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "SAFE MODE" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and 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 and click "Next".
  • 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" and reboot normally.
  • 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.
  • Click Close to exit the program.
Then perform this online Virus scan: BitDefender Online Scanner. <- Add a check by "Autoclean".
(Requires Internet Explorer to work. Watch the Address bar in IE. You may receive alerts that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then Click Install ActiveX component.)
