Critical Vulnerability Found Popup Removal Guide

Do you know what Critical Vulnerability Found Popup is?

Critical Vulnerability Found Popup is a fake alert and fake alerts are used for various purposes. Of course, the most common reason you see these random pop-ups on your browser is money. How these pop-ups reach you is an entirely different question altogether, and we shall try to address it here today. However, the most important thing is that you should ignore Critical Vulnerability Found Popup and then remove everything that could be associated with it from your system. If you are not sure which programs are directly related to such pop-ups, you can always run a full system scan.

It would not be too far-fetched to say that such fake alerts are almost like the next generation of the rogue antispyware infections that used to plague multiple computers worldwide a few years back. However, nowadays, they do not need to infect your computer. They can just compromise your browser and display Critical Vulnerability Found Popup or any other pop-up, making you think that there is something wrong with your system, and a dangerous program has entered your computer. Needless to say, these pop-ups are created to trick unsuspecting users into spending their money on non-existent security programs. Worse, these fake alerts could also trick you into giving away your credit card information, so you should always be careful about the purchase forms you fill out.

According to our research lab there are two main reasons that could cause Critical Vulnerability Found Popup to appear. First, you may see this pop-up as a redirect when you enter a website that automatically generates random pop-ups. If that is the case, you need to close the pop-up window and the website immediately, and then scan your computer to see whether you have potentially unwanted programs on-board.

The second reason is closely related to these potentially unwanted programs. It could be that the pop-up is generated by some adware or potentially harmful program that you installed recently. Of course, no one wants to install unfamiliar and dangerous programs on their systems, but sometimes users may not be aware of the fact they install several applications at once. It usually happens when you download and set up programs from third-party sources, especially the so-called file-sharing sites. It is important to understand that these sites do not review the installers they host, it is really easy for malevolent third parties to spread their programs like that.

Of course, if it is your first time dealing with such a pop-up, it might look dangerous, especially as it says the following:

Critical Vulnerability Found!
Download and Install ANTIVIRUS immediately!
OS type: Windows XX
Press OK to begin the repair process.

If you were to press the OK button, you would be redirected to a website that either collects personal information or distributes malware. Perhaps you would get involved in some online marketing scheme that eventually swindles you out of your money, so you should most certainly ignore the pop-up, and look for ways to avoid it.

According to our researchers, perhaps the most efficient way to get rid of Critical Vulnerability Found Popup is to reset your browser’s settings to default. It is not complicated, and you may not need an antispyware program for that. On the other hand, if you think that this fake alert must have been generated by some unwanted program, then you should definitely scan your computer with SpyHunter free scanner. A full system scan will help you determine which programs are potentially malicious, and you will be able to remove them at once.

As far as the future is concerned, you will yourself a favor if you stay away from unfamiliar sites that could be associated with fake alerts, adware, browser hijackers, and other potential security threats. If you must download some software, please do so from a reliable source.

Next, you should invest in a computer security tool that would safeguard your system and your personal information from malicious exploitation. Safe web browsing habits and a security tool are a straight way to a safe computer.
