Hi, I'm brand new at using a forum and/or trying to fix my computer, so I'm really hoping you guys can help. This is the infection I believe my computer has: Info from the window that comes up when I go to my home page Charter.net. (I use the F-Secure that comes with the Charter package). MALICE CODE FOUND IN FILE C:\Windows\System32\gaopdxqtdpyk.dll. INFECTION: Rootkit.Win32.TDSS.gxu ACTION: THE FILE WAS RENAMED. My computer has been acting wacky for about two month and then I started getting message that it wouldn't update. Then next the Symatics/Norton stopped being able to update, ( I uninstalled it and changed back to F-Secure ). Lots of "redirecting" I believe is the term you use and lots of pop-ups and on and on... I did some searching on-line for answers and you folks came up as the top, so again I'm hoping you can help. Thank You. PS. I have Vista as my OS.

Please download Malwarebytes Anti-Malware (v1.36) 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.

IMPORTANT NOTE: One or more of the identified infections (gaopdxqtdpyk.dll) was related to a rootkit component which includes gaopdxserv.sys, gaopdx[random characters].dll and other malicious files. This is a nasty variant of the TDSSSERV rootkit . Rootkits, backdoor Trojans, Botnets, and IRCBots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control again. and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:Although the rootkit was identified and 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 this malware has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:
