Security Defender, or Defender Pro 2015 as it's shown on the program's web site, is a rogue anti-spyware program that displays fake security alerts, false scan results, and blocks you from running your legitimate programs. This program may look familiar as it tries to impersonate Microsoft Security Essentials by using the same graphical user interface. This scareware is distributed through web sites that have been hacked to run exploit kits that try to install the program by exploiting vulnerabilities on your computer. It is also distributed by Trojans that pretend to be programs required to view an online video, but instead install the infection. These types of Trojans are typically encountered on adult web sites.
When installed, Security Defender will run from your Documents folder and then configure a Windows registry key to start the program every time you login to Windows. Once started it will pretend to perform a scan of your computer that will state you have numerous infections present. If you try to use the program to remove these threats, though, it will prompt you to first purchase the program. As the scan results are fake, please ignore them.
Security Defender also attempts to protect itself from being removed by terminating any program that you try to run. When it terminates a program it will then state that the file is infected with different types of infections such as Win32/Wadnock. The text of this message is:
Review harmful or potentially unwanted software
Your computer might be infected with: Win32/Wadnock.
Windows has detected potential threat that might compromise your privacy or damage your computer. This trojan is dangerous and executes commands from an attacker.
Your access to this program may be suspended until you take an action.
As this alert is false and only designed to scare you, please ignore it.
While the infection is running it will also display a variety of alerts and sounds that are meant to scare you into thinking your computer has a problem. Some of these scare tactics are truly bizarre such as displaying a strange noise and then making your screen appear distorted. Some of the text alerts you may see include:
Virus detection alert.
System has detected security setting changes due to malware. This threat is dangerous, exploits the computer, and provides access to user files. A scan required to complete remediation.
System attack detected.
Unknown program tries to collect a personal info, compromise your privacy, or damage your PC.
Attack from: 249.251.51.131 port: 18280
Attack port: 37825
Just like the scan results, these security alerts, noises, and screen distortions are all meant to scare you into purchasing the program and should be ignored. Finally, Security Defender will hijack your web browser so that you cannot browse the web. When you attempt to do so, you will be shown a page that states that the site you are visiting may be a security risk.
As you can see, this infection was created to scare you into thinking your computer has a security problem so that you would purchase the program. It goes without saying that you should not purchase it, and if you already have, please contact your credit card company and dispute the charges. To remove Security Defender, Defender Pro 2015, and related malware please use the guide below.
Self Help Guide
If you are uncomfortable making changes to your computer or following these steps, do not worry! Instead you can get free one-on-one help by asking in the forums.
- 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.
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.
- 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.
- At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any any infections or adware that may be present. Please download Malwarebytes 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 mb3-setup-1878.1878-18.104.22.1689.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 it will automatically download and install it before performing the scan.
- MBAM will now start 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.
- 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 Remove Selected button to remove all the seleted 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.
- 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:
How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector
Your computer should now be free of the Defender Pro 2015 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.
