“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 FortectIntego software.

How to prevent from getting malware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
