I don't have any recollection of how it happened, but my system appears to have been infected by quite a bit of Malware and Trojans that the spyware/anti-virus programs I usually use have had a lot of trouble removing. Lately, my system has been uncharacteristically slow and takes longer than usual to operate. I have tried System Restore multiple times, but each time it fails (infected restore points?) My system operates on Windows XP.

I've used SUPERAntiSpyware, Spyware Blaster, Spybot, and Adware ..... but the problems still persist. Some of the problems that commonly show up are programs such as Smitfraud-C, Virtumonde, and Win32.Agent.icb (to name a few off the top of my head ...) I've also been using aVast home edition as my anti-virus program, and ever since my system became infected, it identifies various rootkits on a seemingly daily basis which it then removes.

What is the best way to permanently cleanse my system of these problems?

Thanks in advance for your assistance!

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it.

  • Before saving any of your security programs, rename them first. For example, before you save Malwarebytes', rename it to something like MBblah.exe and then click on Save and save it to your desktop. Same thing after you install it. Before running it, rename the main executable file first

    Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

    If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run..
  • Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • 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 updates, manually download them from here or 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 and exit MBAM.
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 you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.
For a complete visual tutorial of MBAM, see http://thespykiller.co.uk/index.php/topic,5946.0.html

IMPORTANT NOTE: One or more of the identified infections was a backdoor Trojan. Backdoor Trojans, IRCBots and Infostealers are very dangerous because they provide a means of accessing a computer system that bypasses security mechanisms and steal sensitive information like passwords, personal and financial data which they send back to the hacker. Remote attackers use backdoor Trojans as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge. Read Danger: Remote Access Trojans.

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 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 again. 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 infection 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:

"When should I re-format? How should I reinstall?"
"Help: I Got Hacked. Now What Do I Do?"

Sorry for taking a while to get back to you

I ran the SuperAntiSpyware scan in safe mode and it found nothing ... here is the log results.

SUPERAntiSpyware Scan Log

Generated 05/24/2009 at 10:52 PM

Application Version : 4.26.1002

Core Rules Database Version : 3909
Trace Rules Database Version: 1853

Scan type : Complete Scan
Total Scan Time : 03:21:59

Memory items scanned : 226
Memory threats detected : 0
Registry items scanned : 7079
Registry threats detected : 0
File items scanned : 79308
File threats detected : 0

However, while I was in safe mode, I also tried to run a scan with Spybot. I usually use Spybot, but ever since I started having these problems on my system, Spybot would not scan completely. The scan would start but then it would die and I would have to kill the process. The scan did run successfully in safe mode and it found the following infections (which Super missed completely :thumbsup: )


Spybot claims that it successfully removed these infections ....

Malwarebytes Anti-Malware has been updated to v1.37. Please download and install the most current version from here.
You may have to reboot after updating in order to overwrite any "in use" protection module files.

Update the database through the program's interface (preferable method). Then perform a new Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.
