What is WindowsActivationUpdate?

WindowsActivationUpdate is a fraudulent program that seeks to deceive the computer user and make him call technical support scammers. WindowsActivationUpdate virus can silently enter your computer alongside another program as an additional component, and once it infiltrates the computer, it takes control over it. The research shows that this type of computer threat cannot initiate malicious activities on PC; however, it will try to deceive you and convince you to call a fake customer support helpline number.

As soon as it launches, it reboots victim’s computer and opens fraudulent screen instead of the usual Windows login screen. This fake screen asks the user to enter Windows Product Key to activate the operating system, but no key will work. No matter how many times you will enter your Windows Product Key, it will be considered invalid. When the victim loses patience, he might start to think about contacting customer support number, which, unfortunately, is a fake tech support number. It is highly advisable not to do so as these frauds will only try to take advantage of you and possibly try to convince you to pay money to get a fake computer security software. However, it seems that authors of WindowsActivationUpdate malware want to get remote access to victim’s computer. If you called them, they would try to persuade you to use one of the buttons provided above and launch a remote access software. As you can see, it suggests using even three different programs – TeamViewer, Supremo, and LogMeIn. You should never give remote access to “technical support” workers if they ask you to do that over the phone.

You should ignore warnings and deactivate this malware, and then remove WindowsActivationUpdate from your computer. For that, you can use Reimage anti-spyware software.

How did this program hijack your computer?

To secure your computer from WindowsActivationUpdate hijack, you should stay away from untrustworthy file sharing networks, shady torrent sites because you can accidentally install a bundled program that includes several bonus components, for instance, the app that we are discussing in this article. We also recommend you to double-check the reliability of your download – when you open its installer, pick Advanced or Custom settings for the installation and then look if there are any suggestions to install unknown software, add browser plug-ins, or change your home and new tab page. Then deselect all of them and install your desired program without any bonus components.

We also recommend you to be very careful while browsing the Internet. Remember that untrustworthy websites can be dangerous, and simply clicking on a “funny cats” or “you won’t believe what happens next” and similarly named articles or videos can activate a malicious link that will automatically download a questionable program to your PC. Be attentive and watch what you click on!
