Microsoft warns of software masquerading as Microsoft Security Essentials when it is actually malware. This file will be executed to trigger the blue screen known as the "screen of death". The typical Windows screenshot with white letters when something goes wrong.

This is actually a scam that pretends that we contact a so-called Microsoft technical support in order to solve it. In order to unlock the device, they will ask us for an amount of money.

Microsoft warns of this type of malicious software and the alleged scam asking its users for money to be able to continue using the computer normally.

How to detect and remove this malware?

The first thing we have to do is verify some steps to make sure that it is indeed the malware that impersonates Microsoft Security essentials. For this method we have several ways to find out.

  1. Microsoft does not use any official installer for Microsoft Security Essentials, this malware uses one called "setup.exe"
  2. The official blue screen does not offer any private or company data, the malware tells us to call a phone number.

    - File properties are different from Microsoft where volume is less than 1 MB.

To solve the problem (which does not really exist) they will ask us for an amount of money at the telephone number that we will find in the bottom of the blue screen. If any user makes the payment, it will continue with the screen in blue color and showing the same problem.

To remove this malware we just have to disconnect our computer from the Internet and use Windows Defender to remove the malware. It is important that the computer is not connected to the Internet so that it cannot act.

Note that Microsoft states that users of Windows 8 or Windows 10 do not need security essentials as that same functionality is covered Thanks to Windows Defender.

Have you come across this type of malware? Were you able to fix it easily?
