'Microsoft has detected suspicious activity' Pop-Ups
The 'Microsoft has detected suspicious activity' pop-ups are part of a technical support hoax whose purpose is to convince users to pay for expensive yet useless software and technical support services. Unlike many other technical support tactics, the t'Microsoft has detected suspicious activity' pop-ups don't appear in the user's Web browser. Instead, they work as a lock screen that prevents the users from accessing their desktop and applications. The entire messages that the 'Microsoft has detected suspicious activity' pop-ups promote states that the user's network security has been breached, and that Microsoft has prevented access to the device that protects the user's data. The last paragraph of the message tells the users to contact 844-879-4840 where they'll get help from a Microsoft certified technician. The lock screen uses the default Windows 10 wallpaper as a background image, probably as an attempt to make the message seem more believable.
Although the message may seem legitimate to some inexperienced users, a closer look reveals multiple grammar mistakes that reputable companies like Microsoft would not include in their error messages. Furthermore, Microsoft and other tech giants would never promote their support services via browser pop-ups, lock screens and similar techniques that may prevent users from accessing their computers' features. It is clear that both the 'Microsoft has detected suspicious activity' pop-ups and the 844-879-4840 are linked to the same technical support tactic. If this message appears on your computer, you should take the necessary actions to eliminate the software responsible for it immediately. Keep in mind that any error message that the 'Microsoft has detected suspicious activity' pop-ups report is fake and should not be trusted.
