Internet Defender is a rogue anti-spyware program from the same family as Security Defender. When Internet Defender is installed onto a computer it will be configured to start automatically when Windows starts. Once started it will perform a fake scan of your computer and then state that there are numerous infections present. If you attempt to remove any of these so-called infections with the program it will state that it is unable to do so until you purchase it. As none of the infection files actually exist on your computer, please disregard these scan results and do not purchase the program.

There are a total of 8 images you can view.

 

While Internet Defender 2011 is running it will also display numerous fake security alerts warnings that are designed to make you think that your computer has a severe security problem. The text of these messages are:

Internet Defender
Your system has come under attack of harmful software. Click here to deactivate it.

Internet Defender
External software tries to control variety of your system files. This may lead to breaking of some data in your system. Click here to protect remote access to your PC & delete these programs.

Internet Defender

Internet Defender Firewall Alert
Suspicious activity in your registry system space was detected. Rogue malware detected in your system. Data leaks and system damage are possible. Please use a deep scan option.

Internet Defender Firewall Alert

Internet Defender Firewall Alert
Your computer is being attacked from a remote machine!
Block Internet access to your computer to prevent system infection.
Attacker IP: <ip address>
Attack type: RCPT exploit

Just like the scan results, all of these warnings are fake and should be ignored.

As you can see, Internet Defender was created for one reason; to scare you into thinking your computer is infected so that you will then purchase the program. For no reason should you purchase Internet Defender, and if you already have, you should contact your credit card company and dispute the charges stating that the program is a computer infection. Finally, to remove this infection, and related malware, please use the removal guide below.

Automated Removal Instructions for Internet Defender using Malwarebytes Anti-Malware:

 

  1. Print out these instructions as we may need to close every window that is open later in the fix.

  2. Reboot your computer into Safe Mode with Networking. To do this, turn your computer off and then back on and immediately when you see anything on the screen, start tapping the F8 key on your keyboard. Eventually you will be brought to a menu similar to the one below:


    MalwareBytes Anti-Malware Screen

    Using the arrow keys on your keyboard, select Safe Mode with Networking and press Enter on your keyboard. If you are having trouble entering safe mode, then please use the following tutorial: How to start Windows in Safe Mode

    Windows will now boot into safe mode with networking and prompt you to login as a user. Please login as the same user you were previously logged in with in the normal Windows mode. Then proceed with the rest of the steps.

  3. It is possible that the infection you are trying to remove will not allow you to download files on the infected computer. If this is the case, then you will need to download the files requested in this guide on another computer and then transfer them to the infected computer. You can transfer the files via a CD/DVD, external drive, or USB flash drive.

  4. Before we can do anything we must first end the processes that belong to Internet Defender so that it does not interfere with the cleaning procedure. To do this, please download RKill to your desktop from the following link.

    RKill Download Link - (Download page will open in a new tab or browser window.)

    When at the download page, click on the Download Now button labeled iExplore.exe download link. When you are prompted where to save it, please save it on your desktop.

  5. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Internet Defender and other Rogue programs. 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 you can continue with the next step. If you get a message that RKill is an infection, do not be concerned. This message is just a fake warning given by Internet Defender when it terminates programs that may potentially remove it. If you run into these infections warnings that close RKill, a trick is to leave the warning on the screen and then run RKill again. By not closing the warning, this typically will allow you to bypass the malware trying to protect itself so that RKill can terminate Internet Defender . So, please try running RKill until the malware is no longer running. You will then be able to proceed with the rest of the guide. Do not reboot your computer after running RKill as the malware programs will start again.

    If you continue having problems running RKill, you can download the other renamed versions of RKill from the RKill download page. Both of these 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.

  6. Now you should now download Malwarebytes Anti-Malware, or MBAM, from the following location and save it to your desktop:

    Malwarebytes Anti-Malware Download Link (Download page will open in a new window)

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

  8. Double-click on the icon on your desktop named mbam-setup.exe. This will start the installation of MBAM onto your computer.

  9. 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, make sure you leave Launch Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes prompts you to reboot, please do not do so.

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


    Malwarebytes Anti-Malware

    Please click on the Scan Now button to start the scan.

  11. If there is an update available for Malwarebytes, the program will prompt you as shown in the image below.



    Update Prompt


    Please click on the Update Now button to update the programs definitions before you perform a scan. When the update has finished, Malwarebytes will automatically start to scan your computer.

  12. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you go and do something else and periodically check on the status of the scan. When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different than what is shown in the image below due to the guide being updated for newer versions of MBAM.


    MalwareBytes Scan Results


    You should now click on the Apply Actions button to remove all the listed malware. MBAM will now delete all of the files and registry keys and add them to the programs 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.

  13. You can now exit the MBAM program. If Malwarebytes did not prompt you to reboot your computer, please do so that you are back in normal mode.

  14. As many rogues and other malware are installed through vulnerabilities found in out-dated and insecure programs, it is strongly suggested that you use Secunia PSI to scan for vulnerable programs on your computer. A tutorial on how to use Secunia PSI to scan for vulnerable programs can be found here:

    How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector

 

Your computer should now be free of the Internet Defender 2011 program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future.

If you are still having problems with your computer after completing these instructions, then please follow the steps outlined in the topic linked below:
