What is "Windows protected your PC"?

"Windows protected your PC" is the name of a tech-support scam promoted using a deceptive website. Like most of these scam websites, it often tricks people into believing that they need to contact scammers who pose as 'technicians', since the computers are supposedly infected and blocked. These websites cannot be trusted and the best option is to ignore and close them. They are usually opened by potentially unwanted apps (PUAs) installed on browsers or computers. People do not generally visit these scam websites intentionally.

Windows protected your PC scam

When visited, this website displays a pop-up window presented as a virus alert from Microsoft stating that the visitor's computer is blocked. It encourages users not to close it or to restart their computers. It is stated that the computer is blocked due to illegal software installed on the operating system, the system registration key is illegal, or the operating system has been hacked and is proliferating viruses. To "reactivate" their computers, users are encouraged to contact the Microsoft helpline via the +1-833-779-4992 number. Another pop-up window (orange) states that Windows has protected the computer using the SmartScreen feature and has prevented an unauthorized application from running, which could cause damage. According to this pop-up, the application is called "windows10manger (1).exe". Like the previous pop-up window, this one also encourages people to contact "technical support". Furthermore, it asks if the application can be opened. This is irrelevant, since none of this information should be trusted. This is a fake virus alert, a scam used to trick people into contacting the scammers who designed it. Ignore it and close the window. If this cannot be done in the normal way, close the entire browser using Task Manager. The closed browsing session should not be restored, since this will reopen the scam website.

Scam websites are often opened by installed unwanted apps, which then cause redirects and deliver intrusive ads. The ads include coupons, banners, surveys, pop-up ads, and so on. If clicked, they open potentially malicious websites or run scripts designed to download and install or other unwanted applications. Additionally, many PUAs gather browsing-related data. For example, IP addresses, entered search queries, URLs of visited websites, geolocations, and so on. Developers share the details with other parties who might be cyber criminals - they misuse the data to generate revenue. For these reasons, uninstall PUAs immediately.

"Hard Drive Safety Delete", "Virus Support Alert", and "Windows Is Not Activated" are examples of just a few of these scam websites. There are many others. Typically, they are used to encourage people to contact scammers who then they try to sell dubious software or services. Their goal is to extort money from people in various ways. The aforementioned PUAs also share many similarities. Most are presented as harmless tools, however, once installed, they cause unwanted redirects to scams such as "Windows protected your PC", feed users with ads, gather data, and so on.

How did potentially unwanted applications install on my computer?

Many users download and install PUAs unintentionally. These apps are installed through clicked ads or when software developers employ the "bundling" method to trick people into downloading/installing unwanted apps with other software. They hide bundled apps in "Custom", "Advanced" and other similar settings of the installation/download set-ups. Developers do not provide information regarding the inclusion of apps into set-ups. Frequently, people grant permission for PUAs to be installed/downloaded simply by skipping software setup steps and leaving all available settings unchanged.

How to avoid installation of potentially unwanted applications?

Download computer software from trustworthy and official websites. Do not use Peer-to-Peer networks such as torrent clients, eMule, various untrustworthy websites and other sources of this kind. Check "Advanced", "Custom" and other settings of the download or installation setup and deselect offers to download/install unwanted applications (bundled programs). If you continually encounter advertisements that cause redirects to dubious websites (gambling, pornography, adult dating, etc.), it is very likely that PUAs are already installed on the default browser or operating system. Check for unwanted extensions, plug-ins, and add-ons installed on the browser and remove all unwanted/unknown or suspicious entries immediately. Apply this to unwanted programs installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
