“System Warning” pop-up is fake – it is a message from tech support scammers

System Warning virus

“System Warning” is a fake virus warning popup [1] which is created for the purpose of driving people to believe their computers are in critical condition and need professional repair. Such scams are commonly labeled as Tech Support Scams [2] and are being actively used by modern day hackers.

Microsoft security warning popup 2017 versions have improved a lot compared to the past couple of years. This can be drawn from the fact that the scammers have learned new social engineering tactics which allowed them to create more advanced fraud schemes, one of which will discuss below.

Once the victim is convinced that he/she has some problems related to PC's security, he/she is asked to dial the number which is given in the fake system warning to contact Microsoft Help and Support service.

Of course, you should never dial the number given to you on such message because it is fake. People who can be reached via such number are scammers trying to install malware on your computer and swindle your money.

If your search sessions have been interrupted by this misleading alert claiming to be from Microsoft Help and Support service, you are infected with “System Warning” virus.

Technically, it is an adware-type [3] program which hijacks every web browser installed on the system.

Secondly, it alters their settings and may cause a change of your start page or the default search engine. No matter that adware-type viruses are not considered dangerous, they can't be called harmless as well.

They can not only lead you to malicious websites by redirecting your browser and cause misleading ads on your computer's desktop. They can also track you and collect NPII [4] without your consent. However, the main task of Tech support scams is to cause fake ads telling that your computer in not protected. To prevent them, you need to remove “System Warning” from your computer. For that, you can use Reimage.

If you have been seeing fake System Warning ads for a while, you should stay away from it! Some years ago, it had been used for promoting rogue anti-spyware application called System Protector.

At the moment of writing, it seeks to scare PC users into believing that their computers are seriously infected and claims “Your computer is not protected!”.

As we have already mentioned, it claims that it belongs to Microsoft Help center, but believe us it has nothing to do with it. This fake warning message seeks to swindle people's money by pushing them into thinking that they can dial some number for the free assistance.

If you would call this number, you would have a conversation with a scammer who will do its best to lengthen the conversation as much as possible. If you don't want to receive an increased telephone bill or install a dangerous program on your computer, stay away from this fake pop-up window.

If you have been convinced by this fake Microsoft employee that you need to install additional software on your computer and you have already done that, you need to check your computer for malware. Besides, the same is recommended if you want to take care of “System Warning” pop-up removal. You can leave this task for anti-spyware programs that are given at the end of this article.

Ways to keep fraudulent programs away from your OS

To prevent System warning hijack, you need to stay away from adware and viruses. Adware, browser hijackers and similar PUPs have been actively spread around the Internet with the help of “bundling”.

This method cannot be initiated without the user – he or she is the one who selects the program and follows the installation wizard. However, when you install programs straight from the Internet, you need to check the developer first and users' reviews to get more information about the program.

Then, make sure you double check optional components of the software to prevent the installation of the unwanted ones. For that, we highly recommend selecting Custom or Advanced installation option and then unchecking pre-checked check boxes that claim that you want to install additional components on your computer.

Programs that you should avoid:

  • various toolbars,
  • browser add-ons,
  • extensions,
  • plugins,
  • scanners and other system tools.

If you have been suffering from “System Warning” redirect programs and similar problems while browsing the Internet, you are hijacked. Make sure you follow a guide below.

Helpful tips on how to remove fake warning from Microsoft Edge

While most computer users tend to pin all the nastiest infections on Internet Explorer, its successor, Microsoft Edge is no less vulnerable to them either.

  • Finally, don’t believe everything you see online. Security warnings and other system related notifications won’t show up on random web pages. If you see one, close your browser and run a system scan to learn whether your PC is not infected with malware.
