Win 7 Defender 2013 and it’s variants initially appear to be a legitimate anti-malware programs, but they don’t serve their advertised purpose. Win 7 Defender falls under the category of scareware, because it’s primary function is to scare you into purchasing it to clean-up bogus malware infections that it supposedly finds through it’s system scans. And to increase the scare factor, it constantly pops up with bogus warnings of malicious software that it has located on your computer, while hindering you along the way.

Win 7 Defender 2013 is primarily spread utilizing two techniques. The first is by drive-by installs in which infected websites exploit vulnerabilities in your web browser and operating system.  When you visit one of the infected sites, the rogue software installs in the background, without your knowledge or consent. The second technique that is used to spread infections of Win 7 Defender 2013 is by questionable websites displaying bogus anti-virus scans and warnings of virus infections on your system. And for you to select to install software to remove the infection. Afterwards, things only get worse for you once the scareware takes hold of your system, when you actually would have thought that you were helping the situation.

After installation, Win 7 Defender 2013 makes changes to the Windows registry and it prevents you from starting any executable programs. Anytime that you attempt starting any program, Win 7 Defender pops up with it’s bogus warnings about multiple infections that it has supposedly located on your system. The warnings are all fake of course. And are meant to scare you into purchasing a license for the bogus anti-virus program, that will do nothing to help your situation.

How to remove Win 7 Defender 2013 and it’s variants from your computer

Before you start, we always suggest hat you back up your important data to usb flash drive or some other external media. Unfortunately though, this particular scareware will most likely hinder your attempts at making a backup copy of your files. So, you’ll probably have to remove Win 7 Defender or at least terminate it’s processes before you can do anything else constructively.

You will need access to an alternate computer system to download files for the removal of Win 7 Defender. The list of files that you will need for this removal procedure is small.  You will need to download the files below on that alternate system and then copy them onto the infected system or just simply execute them from a flash drive or burned cd on the infected computer.

You’ll need to download:

  1. rKill
  2. Combofix
  3. Malwarebytes

Win 7 Defender removal procedure:

  1. First, restart your computer into “Safe Mode with Command Prompt”, by pressing the function “f8” key at the precise time at start-up

  1. Second, once you have made it to the Windows desktop, execute “rKill”, from your external media or device, that you downloaded and copied from your alternate clean computer system, by utilizing the “Command Prompt”

  1. Once “rKill” completes it’s process,  disable any anti-virus utility programs that you already have installed on the computer and run a scan with “Combofix”, by starting it from the “Command Prompt” as well. Depending on your computers’s specifications, it probably will take a little over 15 minutes to complete. It’s important that you don’t interrupt it by trying to open other programs on your system while it’s performing it’s scan.

  1. Next, after “Combofix” has completed it’s scan, reboot your computer system into normal mode.  
  2. Once the computer restarts, install, update and run a full scan with “Malwarebytes” and repair any infected files that it locates. And just in case, restart your system afterwards.
  3. That’s it, you’re done! Your computer should be free of the Win 7 Defender scareware at this point.
