“Validate copy of your Microsoft Windows” error – what should be your next move after this pop-up appears?

If you have unexpectedly encountered a request to “Validate copy of your Microsoft Windows,” chances are, your computer is infected with “Validate copy of your Microsoft Windows” malware, which is better known as Fake Windows Activation virus. This virus proliferates due to Trojan horse technique used for its distribution and manages to infect many computers this way. Once installed, this malicious program launches a fake screen stating that user’s Windows copy did not pass genuine validation/appears to be pirated/or cannot be activated for some other feigned reason. Such virus ALWAYS displays a “Toll-free” technical support number asking the victim to dial it for help. In this case, the virus can display this or a similar line in the message:

Contact Support US/CA Toll-Free 1-800-931-9159

However, people behind phony 1-800-931-9159 tech support line are scammers who seek to take advantage of miserable users who do not know how real Windows Activation screens look. Scammers that pose as “certified Microsoft technicians” typically just pull the wool over victim’s eyes and tell tales that computer has some problems that can be fixed only with particular paid software. However, scammers might also ask you to provide personal information, for example, credit card details, for some bizarre reason, for instance, “to verify your identity.” In some cases, scammers ask to provide them remote access to the computer so that they can fix the computer. Do not react to such trickeries and stay cautious. If you ever call a vague tech support number and the person on another end of call asks you to buy a particular software, provide your bank card details or even give him/her remote access to your PC, hang up. For “Validate copy of your Microsoft Windows” removal, we recommend using the Reimage software. You must remove “Validate copy of your Microsoft Windows” without any hesitations because the program displaying this screen to you can be more dangerous than it seems at first sight.
