Hello tech pro's :flowers:

I understand you guys are really busy, so if it takes time to get to my thread, I understand and I am being patient.


I am a music lover. This morning I found myself on this website [http://idmbreakingnews.blogspot.com/] where I clicked on a link to download some music. Silly me for being so trusting. I ended up with a Trojan called Rootkit.Win32.Agent.pp

I have Norton Antivirus installed (with definitions as current as this morning) and I ran a full system scan. Norton picked up the Trojan and 'supposedly' repaired the problem. I, however, dont trust that all the 'baddies' are gone from my machine. The reason for this is because I did some research on the specific Trojan and what I read is that it hides other programs in your computer. I know antivirus programs sometimes miss things, so my question is this.... Can somebody please help me to thoroughly scrub my computer of any potential 'bad guys' that may be hidden? I would be very appreciative.

I am currently using a different (clean/fresh OS install) computer in my house to write this thread.

Thank you for your time :thumbsup:

IMPORTANT NOTE: Rootkit.Win32.Agent.pp is related to a rootkit component. Rootkits, backdoor Trojans, Botnets, and IRCBots are very dangerous because they compromise system integrity by making changes that allow it to be 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 again. Banking 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 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:Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. If you wish to proceed, please do the following.

Please download Malwarebytes Anti-Malware (v1.41) 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.

Please download TFC by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Please download and scan with Dr.Web CureIt - alternate download link.
Follow these instructions for performing a scan in "safe mode".
If you cannot boot into safe mode or complete a scan, then try doing it in normal mode. Be aware, this scan could take a long time to complete.
-- Post the log in your next reply. If you can't find the log, try to write down what was detected/removed before exiting Dr.WebCureIt so you can provide that information.

Well, first off, thank you for taking the time to respond to my post.

It all sounds very severe.. or possibly severe. I am opting to fully re-install my operating system.

A few questions..

When I re-install the operating system (WinXP sp2 from disk) what is the best way to format the drive in order to ensure all possible 'baddies' are gone? Do I need to repartition the drive? Will a full re-install really remove everything?

I have Norton Anti-Virus as previously mentioned in my opening post. Once I have the operating system freshly installed (making sure the Windows firewall is activated) and I have installed Norton Anti-Virus (from disk) on the hard drive.. when I re-establish my internet connection with my ISP, will I be safe from intruders until I can fully update the Norton definitions and WindowsXP OS updates?

Next question, I have an external hard drive that I regularly backup music and photo files onto. This backup drive hasnt been exposed to the infected computer at all since it became infected. This may sound obvious, but should I feel safe transferring these backed up files onto my hard drive once the OS has been freshly installed?

Thanks for the help :thumbsup:

Your decision as to what action to take should be made by reading and asking yourself the questions presented in the "When should I re-format?" and What Do I Do? links previously provided. As I already said, in some instances an infection may leave so many remnants behind that security tools cannot find them and your system cannot be completely cleaned, repaired or trusted. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore with a vendor-specific Recovery Disk or Recovery Partition removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. Should you decide to reformat or do a factory restore due to malware infection, you can back up all your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, .htm, .html, .xml ) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executable files inside them as some types of malware can penetrate and infect .exe files within compressed files too. Other types of malware may even disguise itself by adding and hiding its extension to the existing extension of file(s) so be sure you look closely at the full file name. Then make sure you scan the backed up data with your anti-virus prior to to copying it back to your hard drive.

If your CD/DVD drive is unusable, another word of caution if you are considering backing up to an external usb hard drive as your only alternative. External drives are more susceptible to infection and can become compromised in the process of backing up data. I'm not saying you should not try using such devices but I want to make you aware of all your options and associated risks so you can make an informed decision if its worth that risk.

Again, do not back up any data with the following file extensions: exe, .scr, .ini, .htm, .html, .php, .asp, .xml, .zip, .rar, .cab as they may be infected.

Should you decide to reformat and you're not sure how to do that or need help, please review::These links include step-by-step instructions with screenshots:Vista users can refer to these instructions:Don't forget you will have to go to Microsoft Update and apply all Windows security patches after reformatting.

when I re-establish my internet connection with my ISP, will I be safe from intruders until I can fully update the Norton definitions and WindowsXP OS updates?

After installing your anti-virus, the first thing to do when connecting to the net is to update it first for max. protection, then get your Windows updates.

Note: If you're using an IBM, Sony, HP, Compaq, Toshiba or Dell machine, you may not have an original XP CD Disk. By policy Microsoft no longer allows OEM manufactures to include the original Windows XP CD-ROM on computers sold with Windows preinstalled. Instead, most computers manufactured and sold by OEM vendors come with a vendor-specific Recovery Disk or Recovery Partition for performing a clean "factory restore" that will reformat your hard drive, remove all data and restore the computer to the state it was in when you first purchased it. See Technology Advisory Recovery Media. If the recovery partition has become infected, you will need to contact the manufacturer, explain what happened and ask them to send full recovery disks to use instead..

If you need additional assistance with reformatting or partitioning, you can start a new topic in the Windows XP Home and Professional forum.

Hi quietman7,

I am in the process of reinstalling WindowsXP Pro in order to start fresh and hopefully be free of this rootkit. I am curious if it is necessary to run Active@KillDisk in order to be assured of complete removal of the rootkit. I've already deleted the partition and run a regular speed NTFS format. Should I go back and run Active@KillDisk? ..or will the steps I've taken be enough to remove the rootkit?
