What is Windows Defender Security Center POP-UP Scam
Windows Defender Security Center POP-UP is a tech-support scam that falsely claims your computer is infected with malware and has thus, been blocked. It’s a very typical scam that essentially wants you to call a fake tech support number. The purpose of such scams is to trick people into paying hundreds of dollars for services they neither needed nor received.
Tech-support scams are mostly identical to one another. They all follow the same pattern, even if they’re operated by different scammers. The first step of this scam is to redirect users to fake Microsoft or similar websites and show them a bogus virus alert. The alert, in this case, claims that “Access to this PC has been blocked for security reasons”. It proceeds to try to intimidate users by claiming that their computers are infected with malware that steals files and data. To remove the infections, the alert asks that users call the displayed phone number.
If you were to call the provided number, you would be connected to professional scammers pretending to be Microsoft technicians. They would tell you more lies about the seriousness of the issue and request remote access to your device in order to supposedly fix it. If you grant them this access, they will pretend to remove the malware while stealing your files, installing questionable programs, and likely set a password for the computer. By the end of the supposed malware removal session, the scammers will demand that you pay hundreds of dollars for the services you supposedly received. If you refuse to pay, scammers might not give you the password they set.
Tech-support scams are always very obvious because they appear in a browser. Browsers will never display legitimate virus alerts, only your anti-virus program will. So you can ignore every single virus alert that appears in your browser because it will always be a scam. Furthermore, legitimate alerts will never display phone numbers. Companies like Microsoft never make unsolicited contact with users. If you needed to contact its customer or technical support, you would need to find the numbers on Microsoft’s official website.
Why are you being redirected to a tech-support scam?
You could be redirected to tech-support scams because of two reasons. Either your computer is infected with adware or you browse high-risk websites that trigger redirects. The latter is most likely. Certain websites are considered to be high-risk due to the ads they expose users to. For example, sites that have pornographic or pirated content can often trigger redirects. Fortunately, redirects are easily preventable with the help of an adblocker program.
If you’ve been redirected to this scam more than a couple of times, your computer may be infected with adware. Adware is a minor but quite annoying infection that exists to expose users to sponsored content. If adware is indeed present, you likely don’t even remember its installations. Infections like adware and browser hijackers use software bundling to install on users’ computers without them even noticing. The method used is software bundling, and the way it works is infections can be attached to free software as extra offers. The offers are concealed from users and permitted to install alongside the programs automatically. Explicit permission from users is not necessary. However, the offers are optional so it is possible to prevent their installation. But first, it is necessary to make them visible.
If you want to avoid installing unwanted programs, you need to pay attention when installing free programs, especially ones you don’t download from official websites. During installation, the installation window will recommend using Default settings but if you follow this advice, all added offers will be hidden and allowed to install alongside. If you opt for Advanced (Custom) settings, you will be able to review what has been added and stop them from installing. All you need to do is uncheck the boxes of those offers.
We don’t recommend allowing any offers to install because even if they seem useful at first sight, they will bring nothing but trouble. It’s also much easier to deselect a few boxes than it is to uninstall persistent adware infections later on.

If you’re redirected randomly by the sites you visit, install an adblocker. This should stop not only redirects but also intrusive advertisements and pop-ups. In other words, an adblocker will greatly improve your browsing experience. If you’re redirected regularly because of adware, only removing the infection would stop the redirects. And since adware can be quite persistent, we strongly recommend using anti-virus software to remove Windows Defender Security Center POP-UP Scam adware. You can try to remove the adware manually but, while not impossible, it can be quite troublesome. Nonetheless, you can find instructions for manual removal below this report.
