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.
For more screen shots of this infection click on the image above.
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:

lead to breaking of some data in your system. Click here to protect remote
access to your PC & delete these programs.

into thinking your computer is infected so that you will then purchase the program.

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:
- Print out these instructions as we may need to close every window that is
open later in the fix.
- 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:
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.
- 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.
- Before we can do anything we must first end the processes that belong to
so that it does not interfere with the cleaning procedure. To do this, please
download RKill to your desktop from the following link.
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.
- Once it is downloaded, double-click on the iExplore.exe
icon in order to automatically attempt to stop any processes associated with
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
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
. 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.
- 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)
- Once downloaded, close all programs and Windows on your computer, including
- Double-click on the icon on your desktop named mbam-setup.exe.
This will start the installation of MBAM onto your computer.
- 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.
- MBAM will now start and you will be at the main screen as shown below.
Please click on the Scan Now button to start the scan.
- If there is an update available for Malwarebytes, the program will prompt you as shown in the image below.
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.
- 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.
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
- 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.
- 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:
detect vulnerable and out-dated programs using Secunia Personal Software Inspector
Your computer should now be free of the
Internet Defender 2011
