CA antispyware discovered 11 instances of Multidropper FK on my computer and managed to quarentine 10. The one remaining reference is located at: hkey-local-machine\system\currentcontrolset\enum\root\legacy_ipfilterdriver\0000.
When quarentine this reference and restart the system, Windows will not restart normally. I have to revert to my previous settings. And I get all 11 instances back. I am afraid to mess with the registry alone.
I have run Hijackthis and the reference does not show up. I would like someone to walk me through the process.
Thanks

Bringing an overlooked post up for review, again. Thanks to any First Responder who might look at this.

Hi and welcome to BleepingComputer :thumbsup:

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

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 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.
  • 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.

Note 2:
-- 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. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

That is good news. Let's take a deeper look...

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

I ran Web Cureit and it found no items. Neither did it produce a report. Did I do something wrong?
Thanks

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"
  • 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.
Safe surfing!
