Malware Removal: Perfect Defender

Hi all,

I have been spyware and malware free for two years now.  Yippee!    But my son managed to get a malware under his profile last night and it is the one titled Perfect Defender that will not allow him to go on the internet.   I have tried to remove it through my Verizon Security Suite and Windows Defender.  It acknolwedges it, but after denying it to be run, it keeps coming back.

I see that I am not the only one with this issue, but also see that it is not resolved.   Can you let me know what I need to do to get this malware removed permanently?   I believe I need to run something called HiJackThis.

Thanks and Happy Holidays!

Re: Malware Removal: Perfect Defender

Hi, Cammy,

Yes, we'd like you to post a HijackThis log. Instructions are in the "HOW TO POST..." announcement at the top of the forum. Before you post, also please run a scan with MBAM so you can include that log as well.

* If you are unable to download or install MBAM on your computer, see if you can use a friend's or family member's computer to download MBAM. Use the update link mentioned above to manually update. Once downloaded, rename the program installer "mbam-setup.exe" file to something else like "cammy.exe". Copy the installer file and the update file to a CD or flash drive. Transfer the file to the infected computer.  Install the "cammy.exe" file, then run the update so that you will have the current definitions. After that, run a full system scan and select to have the program REMOVE whatever it finds.

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
    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:

  • 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 (like Spybot's Teatimer),
they may interfere with the fix or alert you after scanning with MBAM.
Please disable such programs until disinfection is complete or permit them to allow the changes.
