- 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 updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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:
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.
- 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 and exit MBAM.
-- If you cannot use the Internet or download any programs from your machine, you are going to need access to another computer (family member, friend, etc) with an Internet connection. Save mbam-setup.exe
to a flash (usb, pen, thumb, jump) drive or CD, transfer it to the infected machine, then install and run the program. If you cannot transfer or install from the infected machine, try running the setup (installation) file directly from the flash drive or CD so it will install on the hard drive.IMPORTANT NOTE
: One or more of the identified infections (TDSSserv.sys
) is related to a nasty rootkit component
and backdoor Trojans
are very dangerous
because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. 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 backdoor Trojans
and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.
If your computer was used for online banking, has credit card information or other sensitive data on it, you should immediately disconnect from the Internet until your system is 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
. You should change each password by using a different 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 before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
Although the rootkit 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 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:
