Hullo! first post and i'm really honoured to join a community of such knowledgeable persons! Anyway..

Running XP Pro 2002 SP2, Kaspersky Internet Suite 7.0.1.325 c.d, Spybot S&D. Previously also running Spyware Doctor but was uninstalled.

Originally became infected with Virtumonde.dll along with Adware.AdMedia and various other problems at once (can't remember exactly how - was 6 weeks ago).

After searching BleepingComputer.com i followed directions with suggested two programs, neither of which succeeded: VirtumundoBeGone & Vundofix.

I then installed Spybot S&D 1.5.2.20 which found and removed 6 Virtumonde.dll entries. It also found DeepDive and reportedly removed it, but still finds and removes instances of it every time i run an automated scan at logon - so far 256 files removed since infection. The removed instances are Browser Helper Objects, Class ID's and Root Class keys from the registry. i have kept Spybot logs.

I also ran Spyware Doctor which removed Trojan.Virutmonde on multiple occasions plus Adware.AdMedia, Adware.Caisha and various other things on other occasions. Unfortunately all Spyware Doctor logs were lost when i uninstalled it recently.

When I close down my pc an 'end program' screen appears stating that pc is "attempting to connect to port 123.." which i end manually and then the pc is able to shut down. This occurs at every use. Not sure how to proceed with a proper removal!

Please let me know if you need any more info to assist! Any assistance would be very helpful!

Thank you!

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_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 and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Acan" 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 and you may be prompted to restart your computer. (see Note below)
  • 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.
Instructions with screenshots if needed.

Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Hi Quietman7,

Thank you for your Guidance, here's the MBAM log from the second scan after i removed the found objects from the first, the same BHO entries appear again:

Malwarebytes' Anti-Malware 1.18
Database version: 873

5:34:08 PM 21/06/2008
mbam-log-6-21-2008 (17-34-08).txt

Scan type: Full Scan (C:\|D:\|E:\|F:\|G:\|)

Files Infected: 0

Memory Processes Infected:

Memory Modules Infected:

Registry Keys Infected:
HKEY_CLASSES_ROOT\bhonew.bhoapp (Trojan.FakeAlert) -> Quarantined and deleted successfully.

Registry Values Infected:

......i selected to remove the BHO's after the 1st scan but the items are still being found which suggests the MBAM cannot remove the entries. Any other thoughts?

UPDATE:

here's the results from a 3rd scan just to show how they return after every pc restart:

There are no shortcuts or guarantees when it comes to malware removal. Sometimes it takes several efforts with different tools to do the job. Even then, with some types of malware infections, the task can be arduous.

Glad to hear the issue has been resolved. However, please note the message text in blue at the top of this forum.

You should not be using Combofix unless instructed to do so by a Malware Removal Expert. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. Please read Combofix's Disclaimer.

Your were fortunate in this instance that no unforeseen consequences occurred. Now if there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.

Thank you for your further advice!

After losing operating systems on numerous occasions in years gone, we established practises to cope and continue work including multi-op sys booting and locating all work data on multiple other drives. We would suggest any person who is serious about maintaining their data integrity and security considers implementing such strategies. Thankfully now the only loss is the time required to restore the affected op sys to the required functional level.

We did a clean install shortly after the virus was contracted a few months ago, and then experienced re-infection almost immediately. Through the process of following your instructions it was found that a dubious program had been downloaded and stored on the data drives, and that this had been the source of the infection and re-infection.

Again we want to say we are extremely thankful for your advice and Guidance, and that we have implemented your final directions.

Kind Regards,
mdrmusic.

You're welcome.

To protect yourself against malware and reduce the potential for re-infection, be sure to read:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Best Practices - Internet Safety for 2008".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".

• Avoid online gaming sites and peer-to-peer (P2P) or file sharing programs as they are a security risk which can make your system susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans target and spread across P2P files sharing networks and gaming sites. In some instances the infection may cause so much damage to your system that recovery is not possible and the only option is to wipe your drive, reformat and reinstall the OS. The best way to reduce the risk of infection is to avoid gaming sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
