Remove “Windows Activation Pro” virus (Call for Support Scam)

If your computer is locked, and you are seeing an “Windows Activation Pro” notification asking you to call a support number to fix it, then your machine is infected with a piece of malware known as Rogue.Tech-Support.
Windows Activation Pro Virus
This Rogue.Tech-Support malicious program displays a “Windows Activation Pro” lock screen when you start Windows that attempts to scare users into calling a remote tech support number (eg: +1-844-459-8882.
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 (1-844-208-3526) 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 “Windows Activation Pro” malicious program is installed it will also change a variety of Windows settings. This allows it to display fake the BSOD alert, 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 “Windows Activation Pro” crash that will be displayed is:

Windows Activation Pro
Product Key Customer Support: 1-844-459-8882

Your computer is suspected of malicious software, for the purpose of verification enter your Windows Activation Pro. You will find your product key on the box that Windows Dvd came in or in the welcome email or on the certificate of authenticity stick. It looks similar to this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

The “Windows Activation Pro” 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 on your credit card company or bank.
