What is known about the “Enter A Product Key” virus:

“Enter A Product Key” virus belongs to a category of computer infections that are designed to trick the users into believing that their Windows license has expired, and they need a new license key to keep the system running as usual. Though similar infections have been around for a while now, an increase in their popularity is especially apparent in the last couple of months. This revival might be related to the new releases of Windows 10 and Windows 10 Anniversary Update. What has is also new with these infections is that they have become more aggressive. Instead of displaying a pop-up notification on the infected computer’s browser like they used to before, now the virus locks the computer’s screen, preventing the system from booting properly. In short, the virus is a tech-support scam with a hint of a ransomware infection. Though this virus does not encrypt the files stored on the computer, the lock screen does not allow the user to access computer’s desktop until the supposed Windows activation issue is solved. But there is a way you can lift the lock screen and remove Enter A Product Key virus from your computer. The virus decontamination instructions are provided below. Do not forget to scan your system with a trusted anti-malware utility like Reimage after completing these steps.

Tech-support virus creators are especially well informed in human psychology. First, they convince their Windows license has really expired, by locking the computer’s screen and preventing the antivirus utilities from exposing this roguery. In the lock screen Enter A Product Key malware shows a message similar to the one presented below:

Enter a Product Key
Your product key should be on the box that the Windows DVD came in or in an email that shows you bought Windows. The product key looks similar to this:
Product Key: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
