Hello all,

My first post here. First - I am pretty computer saavy and have no problem digging under the hood to find, fix or configure things (in other words, most of my friends call me for tech support).

Anyway, I was told by users over at the Norton Community that this virus is particularly difficult to find and remove but that I can find good help from users here. I have a Windows XP machine. Norton found this virus but said that I have to remove it manually. I have looked all over the file system to find this file but cannot locate it. Can anyone point me in the right direction. Many thanks.

Pete

Hello Pete, I am moving this to to the Am I Infected forum from XP>

This works pretty well on this.

Is this PC on a network?

Run a full system scan in safe mode with the latest Norton definitions. Then unplug the network connection and reboot the computer. Does the backdoor.tidserv detection come up again? If so, then we need to search for another undetected process on your computer.


Now run TDDS Killer
Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.



Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.alternate download link 1
alternate download link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thanks for the info! Allow me to give you a bit more info/history. This computer (it's my dad's) appeared to have malware on it. I downloaded the free Malware Removal Tool from Microsoft and it said it found the file but could not remove it. It never told me the name of it or where it was located. It did say to run an Anti-Virus program in order to remove it. So I ran a full Norton scan and it came up with this "Backdoor" virus and told me where it was. I removed the file, rebooted and ran Norton Full Scan again - no viruses.

Then I ran the Malware software again and it said it found an infected file (again, not telling me the name or location). My question is this - could this Backdoor virus be the same malware that the malware scanner found, or am I dealing with two different issues?

Meanwhile I will follow your instructions and see what happens. Thanks again!

Pete

Well I am guessing like you as we have no real info. Did you run the MBAM. Most likely MSE can not remove the Tidserv thats why I posted the Killer..

A backdoor Trojan can allow an attacker to
gain control of the system, log keystrokes, steal passwords, access personal
data, send malevolent outgoing traffic, and close the security warning
messages displayed by some anti-virus and security programs.

I would advise you to disconnect this PC from the Internet, and then go to
a known clean computer and change any passwords or security information held
on the infected computer. In particular, check whatever relates to online
banking financial transactions, shopping, credit cards, or sensitive
personal information. It is also wise to contact your financial institutions
to apprise them of your situation.
