This is my first post here, so I hope I'm following the rules correctly. About week ago while on the internet I received a warning from a webpage that my computer maybe infected and it started to "scan" my machine. At the same time my antivirus software (avast) went nuts. I quickly closed everything, and I thought I was good until a day later when I noticed that when I would click a search result from google I would be redirected to an advertisement. A spybot scan turned up WIN32.TDSS.rtk. I have tried using spybot to remove it without success. I also tried downloading and installing the Kaspersky software without success. Any help to remove this would be appreciated.

OS-WindowsXP


Thank you.

OS-WindowsXP

If that is the case, then your Microsoft Windows installation is out of date and you are using an unpatched version of Windows XP. Before we can proceed any further, please update to Service Pack 1a and install All CRITICAL Updates and security patches except SP2 which will help to prevent crippling malware attacks. Without doing this first, you are wide open to re-infection and other high security risks which are prone to an unpatched system and we are just wasting our time. If you are not sure how to do this, see How to use Microsoft Update. By applying all critical updates, you will close many of these security holes which make your computer vulnerable and not keep getting reinfected while cleaning your machine.

Further, using unpatched Windows systems on the Internet is a security risk to everyone. When there are insecure or infected computers connected to the Internet, malware spreads faster and more extensively, distributed denial-of-service attacks are easier to launch, spammers have more platforms from which to send e-mail and more machines become compromised. Whenever a security problem in its software is found, Microsoft will usually create a patch for it. After the patch is installed, attackers can't use the vulnerability to install malicious software on your computer.

Please download Windows XP Service Pack 1a Express Install (32-Bit) for End Users. Apply the patch and reboot.
Then return to Microsoft's Update Page and install any remaining critical updates for your computer except SP2.
Note: The update process uses ActiveX, so you will need to use Internet Explorer for it, and allow the ActiveX control that it wants to install.

Again, DO NOT update to Service pack 2. Doing so before your computer is clean from malware can cause Windows to become unstable. According to Microsoft, malware seems to be the number one cause of problems when upgrading to XP SP2. You may apply that update when your system has been disinfected and is clean.

After updating to SP1, please download Malwarebytes Anti-Malware (v1.41) and save it to your desktop.

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 is related to a nasty TDSSSERV rootkit component also known as Backdoor.Tidserv. 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. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. 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, you should stay disconnected from the Internet until your system is fully cleaned. 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 and change each password using a clean computer, 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 before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:Although the infection 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 the computer is secure even if the malware appears to have been removed. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired so you can never be sure that you have completely removed a rootkit. The malware may leave so many remnants behind that security tools cannot find them. Tools that claim to be able to remove rootkits cannot guarantee that all traces of it will be removed. 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:
