I have persistent pop-ups ads, mostly for antivirus software. Software performance has slowed considerably, some web pages take forever to load or just never load. I have tried to resolve the issue with McAfee and Spybot Search & Destroy, with no success. McAfee identifies several generations of Vundo trojan.

I ran dds.scr but the log file it generated was all symbols. I don't think i have any script blocking software.

Any help you could offer with this would be greatly appreciated.

Hello.

Please run MBAM first.

Download and run MalwareBytes Anti-Malware

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 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 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.
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.

For complete or visual instructions on installing and running Malwarebytes Anti-Malware please read this link

Hello.

There was a few files that were scheduled to be removed on reboot, so did you reboot? Failure to reboot will prevent MBAM to remove them. Please reboot if you haven't already.

Please reboot now if you haven't already and then update MBAM and this time run a Full Scan please.

Thanks.

With Regards,
Extremeboy

Thanks for the help. I rebooted immediately after running the quick scan, as prompted. After reboot, there was no confirmation the files had been successfully deleted.


After running the full scan, I was also prompted to restart. Here is the log from the full scan:

The popup ads are gone and software performance has improved. The Malwarebytes log shows no malicious items found, but McAfee and Spybot Search & Destroy also would quarantine and delete everything, only to have the popups return. But for now it looks good. Thanks for helping me out.

No Problem.

You may want to purge a system restore point now.

Create a New System Restore Point<- Very Important

Now 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"
  • Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" Tab.
  • Click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
