WindowsActivationUpdate is a trojan horse (Rogue.Tech-Support-Scam) that displays fake product activation screen that is designed to scare you into calling a remote tech support phone number.
The WindowsActivationUpdate malware displays a fake Windows product activation screen that attempts to scare users into calling a remote tech support number. This screen states that your Windows product key is missing and that you need to enter a new one and press the Active Windows button.
These alerts are shown in such a way as to trick the user into thinking their computer has crashed or that a virus has been detected on the computer. It does this to try and scare the infected user into calling one of the listed numbers in order to receive support. In reality, though, they will only be greeted with people who are trying to sell them unneeded support contracts and services.
When the “WindowsActivationUpdate” malicious program is installed it will also change a variety of Windows settings. This allows it to display the fake product activation screen, which overlaps your entire screen, without fear that you can terminate it. In this screen will also be buttons that open the TeamViewer, Supremo, and Logmein sites as well as a button called CMD that opens the command prompt.
The text of the “WindowsActivationUpdate” crash that will be displayed is:
BX06DE489_MD9858
PRODUCT KEY MISING. Active Windows
The “WindowsActivationUpdate” lock screen is a complete scam, and you should not purchase anything from numbers listed in these alerts. If you have already purchased services from them, I would advise you to dispute the charges with your credit card company or bank.
