WINDOWS fake update has been discovered that can infect your computer with ransomware by encrypting all your files so you can’t use the computer again.
One of the most dangerous attacks that we may suffer on our computer is the so-called ransomware, which is when all our files are encrypted and we cannot access them unless we pay a reward. It usually aims at these types of vulnerabilities that are quite common on the Internet at companies.
How to protect from Windows fake update
The first thing is to do it only from official sites. This applies to downloads from official pages and also from app stores, as with mobile devices. Many attackers modify the applications themselves or can introduce fraudulent links that install third-party applications loaded with malware.
Therefore, we must avoid ads that can skip when browsing to update the browser itself or any other application. It must be done only from official sites and always use common sense.
It is also very important to have security programs and tools. This way, we can analyze what we are downloading or installing. We can face threats that put at risk the proper functioning of our equipment.

It is key to have our systems updated. In this way, we can defend ourselves against the latest techniques to introduce malware. Frequently, the systems themselves take security patches to eliminate vulnerabilities that cybercriminals take advantage of.
And finally, although perhaps use common sense. Sometimes cybercriminals use social engineering to cause fear in the user and end up clicking where they want. Display messages reporting errors on the computer, virus threats, etc. They ask, to solve it, update the system. Never do it. Always turn to official sites, as we mentioned.
How to identify fake updates
As we have mentioned, in most cases, these fraudulent updates seek the fear of the user. Make-believe that we need to install or update a program for the proper functioning of the equipment. They usually appear with pop-up messages on pages that have little to do with the real update. Also, they may appear in third applications that, although by themselves, are not dangerous, can show ads of other applications that can be fraudulent.
It is also possible to identify them through the download link. Content unrelated to the program usually surrounds them.

Trustwave security firm has discovered a new ransomware campaign that is based on fear and false warnings about an infection in your operating system. These notices that scare the user are sent to the victim’s email where the threat is included. In this email, the user is urged to run a fake update and that comes through a JPG extension, but that hides the cyborg ransomware.
Once the ransomware infects our computer, the files are encrypted and changed to the extension “777”. From that moment, the user’s files are completely locked, and you only have access to a text document on the desktop where you are given instructions to regain access to the files.
In this text document, the user is asked to send $500 to a Bitcoin wallet so that their files are unlocked, in a procedure in which very few people fall. If you pay the $500 reward, you will lose not only your money but also your files since you will never receive the password so that you can access them again.
If you are infected by ransomware, you cannot do anything at all and the best solution is to format the computer. That is why it is always good to have backup copies of our computer, or at least save all important files or documents on an external hard drive.
You should never open an attachment that comes from an unknown email. However, no company of this caliber will contact you through the mail, so avoid opening such messages to avoid Windows fake updates.
