The fake Microsoft Security Essentials Alert is a Trojan that attempts to trick you into thinking you are infected so that you will then install and purchase one of 5 rogue anti-virus programs that it is distributing. When the Trojan is run it will masquerade as an alert from the legitimate Windows Microsoft Security Essentials Program anti-virus program. This alert will be titled Microsoft Security Essentials Alert and states that a Trojan was detected on your computer. It will list this Trojan as Unknown Win32/Trojan and state that it is a severe infection. It will then prompt you to clean your computer using the program in order to remove it. When you click on the Clean Computer or Apply actions button, it will state that it was unable to remove it and then prompt you to scan online. If you click on the Scan Online button it will list 35 different anti-virus programs, 30 of which are legitimate anti-virus programs and 5 that are rogues that the Trojan is distributing. These five rogue programs are:
- Red Cross Antivirus
- Peak Protection 2010
- Pest Detector 4.1
- Major Defense Kit
- ThinkPoint
- AntiSpySafeguard or AntiSpy Safeguard
During this fake online scan only the 5 fake anti-virus programs listed above will state that this supposed Trojan is an infection. It does this to scare you into clicking the Free Install button next to them that will install the rogue program onto your computer and then reboot your computer. It should be noted that Red Cross Antivirus, Peak Protection 2010, Pest Detector 4.1, Major Defense Kit, AntiSpySafeguard, ThinkPoint, and AntiSpy Safeguard that this Trojan is distributing are exactly the same. They just have different names and different graphical user interfaces. You can see images of each of the above rogues below.
After your computer is rebooted, the rogue that was selected will automatically start and perform a fake scan on your computer. When it has finished it will state that it was able to clean numerous files, but was not able to clean some files, such as iexplore.exe, until the program is purchased. While running, this program will also terminate many programs when you attempt to run them and display a message stating that they are infected. This message is:
The application taskmgr.exe was launched successfully but it was forced to shut down due to security reasons.
This happened because the application was infected by a malicious program which might pose a threat for the OS.
It is highly recommended to install the necessary heuristic module and perform a full scan of your computer to exterminate malicious programs from it.
Furthermore, these rogues will also display security alerts from your Windows taskbar that display messages such as:
Warning! Database updated failed!
Database update failed!
Outdated viruses database are not effective can't guarantee adequate protection and security for your PC! Click here to get the full version of the product and update the database!Warning! Running trial version!
The security of your computer has been compromised! Now running trial version of the software! Click here to purchase the full version of the software and get full protection for your PC!
All of these security alerts, like the scan results, are fake and should be ignored.
As you can see, this Trojan was created to trick you into thinking that you are infected so that you will then download and install one of its rogue anti-virus programs. If you have been tricked by this Trojan and installed Red Cross Antivirus, Peak Protection 2010, Pest Detector 4.1, Major Defense Kit, ThinkPoint, AntiSpySafeguard, or AntiSpy Safeguard then do not purchase it for any reason. If you have already purchased one of these programs, then I strongly suggest you contact your credit card company dispute the charges stating that it is a scam and a computer virus. Finally, to remove the fake Microsoft Security Essentials Alert and the related rogues, please use the removal 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.
- 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
Fake Microsoft Security Essentials Alert Trojan and AntiSpySafeguard
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
Fake Microsoft Security Essentials Alert Trojan and AntiSpySafeguard
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
Fake Microsoft Security Essentials Alert Trojan and AntiSpySafeguard
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
Fake Microsoft Security Essentials Alert Trojan and AntiSpySafeguard
. 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. If you continue
having 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. - 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
this one.
- Double-click on the icon on your desktop named mb3-setup-1878.1878-3.0.6.1469.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.
- 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 Fake Microsoft Security Essentials Alert Trojan and AntiSpySafeguard 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.
