1. This removal guide may appear overwhelming due to the amount of the steps and numerous programs that will be used. It was only written this way to provide clear, detailed, and easy to understand instructions that anyone can use to remove this infection for free. Before using this guide, we suggest that you read it once and download all necessary tools to your desktop. After doing so, please print this page as you may need to close your browser window or reboot your computer.

2. To terminate any programs that may interfere with the removal process we must first download the Rkill program. Rkill will search your computer for active malware infections and attempt to terminate them so that they wont interfere with the removal process. To do this, please download RKill to your desktop from the following link. When at the download page, click on the Download Now button labeled iExplore.exe. When you are prompted where to save it, please save it on your desktop.


3. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with PBlock+ adware browser extension and other malware. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and a log file will open. Please review the log file and then close so you can continue with the next step. If you have problems running RKill, you can download the other renamed versions of RKill from the rkill download page. All of the files are renamed copies of RKill, which you can try instead. Please note that the download page will open in a new browser window or tab. Do not reboot your computer after running RKill as the malware programs will start again.

4. At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any infections, adware, or potentially unwanted programs that may be present. Please download Malwarebytes from the following location and save it to your desktop:

5. Once downloaded, close all programs and Windows on your computer, including this one.

6. Double-click on the icon on your desktop named MBSetup-1878.1878-4.0.exe. This will start the installation of MBAM onto your computer.

7. When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, a welcome screen will be displayed.

At this screen, click on the Get Started button where you will be prompted to buy and activate a license.

To continue using it for free, click on the 'Maybe Later' option and then select 'Use Malwarebytes Free'. It should be noted that the free version will scan for and remove malware, but not provide real-time protection from threats that occur when not performing a scan.

Finally, you will be shown a screen asking you to sign up for their newsletter. Just click on the 'Open Malwarebytes Free' option to start the program.

8. MBAM will now start and you will be at the main screen as shown below.

We now need to enable rootkit scanning to detect the largest amount of malware and unwanted programs that is possible with MalwareBytes. To do this, click on the Settings gear on the top left side of the screen and you will be brought to the general settings section.

9. You should now click on the Scan button to begin scanning your computer for malware. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.


10. When MBAM is finished scanning it will display a screen that displays any malware, adware, or potentially unwanted programs that it has detected. Please note that our guide's scan results image may look different than the one you are shown in this version of Malwarebytes as it was created with an older version.

You should now click on the Quarantine button to remove all the selected items. MBAM will now delete all of the files and registry keys and add them to the program's quarantine.

When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.


11. You can now exit the MBAM program.

12. At this point you should download Zemana AntiMalware, or ZAM, in order to scan your computer for any any infections, adware, or potentially unwanted programs that may be present. Please download Zemana AntiMalware from the following location and save it to your desktop:

13. Once downloaded, close all programs and open windows on your computer.

14. Now double-click on the icon on your desktop named Zemana.AntiMalware.Setup.exe. This will start the installation of Zemana AntiMalware onto your computer.

15. When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, Zemana will automatically start and display the main screen.

16. You will now be at the main screen for Zemana AntiMalware as shown below.

Above the Scan button, please change the scan type to Deep Scan and then click on the Scan button to start the malware removal scan.

17. Zemana AntiMalware will now start scanning your computer for malware, adware, and potentially unwanted programs. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.


18. When Zemana has finished finished scanning it will display a screen that displays any programs that have been detected. Please note that the items found may be different than what is shown in the image below.

Review the scan results and when you are ready to continue with the cleanup process, click on the Next button to delete or repair all of the the selected results. Once you click on the Next button, Zemana will remove any unwanted files and fix any modified legitimate files. If you receive a warning that Zemana needs to close your open browsers, please close any web browsers that may be open and then click on the OK button to continue.

Zemana will now create a System Restore Point and remove the detected files and repair any files that were modified.

19. When the process is complete, you will be shown a screen that says Completed. At this screen, you can now close the Zemana AntiMalware screen and continue with the rest of the instructions.

20. Now please download AdwCleaner and save it to your desktop. AdwCleaner will scan your computer for adware programs that may have been installed on your computer without your knowledge. You can download AdwCleaner from the following URL:

21. When AdwCleaner has finished downloading, please double-click on the AdwCleaner.exe icon that now appears on your desktop. Once you double-click on the icon the AdwCleaner program will open and you will be presented with the program's license agreement. After you read it, click on the I agree button if you wish to continue. Otherwise, click on the I disagree button to close the program. If Windows prompts you as to whether or not you wish to run AdwCleaner, please allow it to run.

If you selected to continue, you will be presented with the start screen as shown below.


22. Now click on the Scan button in AdwCleaner. The program will now start to search for known adware programs that may be installed on your computer. When it has finished it will display all of the items it has found in Results section of the screen above. Please look through the results and try to determine if the programs that are listed contain ones that you do not want installed. If you find programs that you need to keep, then uncheck the entries associated with them.

For many people, the contents of the Results section may appear confusing. Unless you see a program name that you know should not be removed,please continue with the next step.

23. To remove the adware programs that were detected in the previous step, please click on the Clean button on the AdwCleaner screen. AdwCleaner will now prompt you to save any open files or data as the program will need to close any open programs before it starts to clean.
