Posted 27 November 2007 - 08:44 PM

IE was recently infected with some sort of search-hijacking BHO. I don't know its name because it wasn't something that I was able to detect with the latest versions of McAfee, AdAware or VundoFix.

With HijackThis I found reference to 2 very suspicious-sounding .dll files (in C:\WINDOWS\system32), which I was able to delete only by booting from another drive. Now the files have gone everything seems to be working fine, but HijackThis still detects 3 references to them which it can't remove.

IE still lists the 2 files in the "Manage add-ons" window. Disabling them was the first thing that I did, but it doesn't give me the option to delete them.

CCleaner detects the same entries in the registry, but they still remain after it claims to have fixed them. RegEdit won't let me delete them.

Any ideas?

(The 3 items are in bold, but if anyone notices anything else that shouldn't be there please let me know. Thanks in advance!)

SOLVED. (I think!)

If anyone's interested, Spyware Doctor found the registry entries and removed them; apparently the BHO was the PWS.Tanspy trojan. More information here:

http://www.pctools.com/mrc/infections/id/Trojan-PWS.Tanspy

This was after McAfee, Ad-Aware, Spybot, ComboFix and VundoFix all failed to detect anything amiss. Spyware Doctor isn't my favorite piece of software (it takes about 5 minutes to launch and shut down!) but it seems to have done the job: HijackThis no longer lists the nonexistent .dll files, and IE no longer shows them as add-ons.

Thanks to anyone who read this thread. I'm off now to change all my passwords :thumbsup:

Sorry for the delayed response but the Hijackthis forum has been extremely busy as of late and we are all volunteers. You are correct to change all your passwords as one or more of the identified infections is a backdoor Trojan.

Although the backdoor Trojan has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because the backdoor Trojan has been removed the computer is now secure. Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat and reinstall the OS - "When should I re-format?".

Should you decide not to follow that advice, please post a new HijackThis log after doing the following.

Please download SDFix by AndyManchesta and save it to your desktop.
alternate download
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Double click SDFix.exe and it will extract the files to %systemdrive%
  • (this is the drive that contains the Windows Directory, typically C:\SDFix).
  • DO NOT use it 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".

Open the SDFix folder and double click RunThis.bat to start the script.
  • Type Y to begin the cleanup process.
  • It will remove any Trojan Services or Registry Entries found then prompt you to press any key to Reboot.
  • Press any Key and it will restart the PC.
  • When the PC restarts, the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
  • Once the desktop icons load, the SDFix report will open on screen and also save a copy into the SDFix folder as Report.txt.
  • Copy and paste the contents of Report.txt in your next reply.
-- If this error message is displayed when running SDFix: "The command prompt has been disabled by your administrator. Press any key to continue..."
Please go to Start Menu > Run > and copy/paste the following line:
%systemdrive%\SDFix\apps\swreg IMPORT %systemdrive%\SDFix\apps\Enable_Command_Prompt.reg
Press Ok and then run SDFix again.

-- If the Command Prompt window flashes on then off again on XP or Win 2000, please go to Start Menu > Run > and copy/paste the following line:
%systemdrive%\SDFix\apps\FixPath.exe /Q
Reboot and then run SDFix again.

-- If SDFix still does not run, check the %comspec% variable. Right-click My Computer > click Properties > Advanced > Environment Variables and check that the ComSpec variable points to cmd.exe.
%SystemRoot%\system32\cmd.exe
