This scam will try to convince you that there is something fundamentally wrong either with your computer or your browser.

Where does Critical Vulnerability Found Popup come from?

When it comes to tech support scam, there could be many reasons this fake alert appears on your browser. For the most part, users get redirected to the websites that display Critical Vulnerability Found Popup when they access adware-centered pages. For instance, there are a lot of websites that host online videos or various files, and if these sites offer this content for free, they usually need to somehow cover their hosting costs. So they do that by displaying a lot of third-party advertisements.

These advertisements could be embedded even in Search or Play buttons. Sometimes a site could open a new window even if you click your mouse’s cursor on the search bar. Since these websites are not responsible for the third-party content security, you can never know what kind of page you will get redirected to. And so, it is not surprising if the Critical Vulnerability Found Popup is one of those pages you land on.

If you do click the OK button, you will be redirected to yet another website where they will offer some program or perhaps they will ask you to call a given tech support number. Either way, the bottom line is that this message is a scam, and it is generate to scare you into thinking that your computer’s security is at risk.
