Windows Security Warning Popup Scam Removal Guide

Windows Security Warning Popup Scam is a fake alert that can scare you if you are not experienced enough to know that this is just another online scam to push you to buy some security software. You will usually see this fake alert while you are browsing the web and somehow get redirected to a malicious page that displays this warning. Since this message is on blue background and claims to be a Windows security warning, you may even believe so if you do not know better. We have seen several similar fake alerts and technical support scams emerging on the web, including “This PC Has Been Blocked - Screen Locker,” “1-800-953-457 Pop-Ups,” and “Please call us immediately at: (803) 702-1564,” which all have the same goal: To make money out of selling you potentially useless software and IT security services. We believe that you should remove Windows Security Warning Popup Scam from your computer right away to restore your virtual security.

There are basically two ways for you to end up on a malicious page that can display such a fake alert. First, you may be viewing a suspicious website (torrent, freeware, online gambling, gaming, or dating) that can host a number of unsafe third-party ads and links. One click can easily forward you to such a malicious page to end up with a fake alert on your screen. This is obviously the better case because your computer may not be infected; so it could be enough for you to close the browser window right away to eliminate Windows Security Warning Popup Scam. However, this could be a bit tricky because this fake alert may be set to open in full screen so you cannot just simply close it. Later on we will, of course, tell you what you can do in this situation to remove Windows Security Warning Popup Scam from your browser.

Another possibility is that your computer was infected previously by adware programs or other unwanted programs that can perform redirections. If such an infection is on board, you are never really safe to go online because you could be exposed to potentially harmful third-party web content like this fake alert. When an adware program or other unwanted applications are hiding on your computer, it is quite likely that you have installed a freeware bundle from a suspicious file-sharing website or you clicked on a corrupt third-party ad on a shady website promoting such ads. You need to be very careful every time you install a software bundle because it may contain adware programs, browser hijackers, Trojans, fake alerts, and more.

You may be able to deselect these while installing the bundle but some installers are rather pushy and may not let you install the main free software unless you agree to install the additional tools and browser setting changes as well. We advise you to cancel such a process because you could harm your computer easily and make it more vulnerable to cyber attacks. We recommend that you remove Windows Security Warning Popup Scam by trying to identify any suspicious application or browser extension on your computer and then, run a reliable online malware scanner to find all other threats.

We have found two basic types of this fake alert. Both may open in full screen to stop you from closing it easily. These alerts have blue background that can make you feel like it is one of those feared blue screens of death type of errors. Both of these versions try to make you believe that there are some threats on your computer and you need to download an antivirus program to help you with this system security issue. This fake alert seems to promote the well-known McAfee antivirus software but, obviously, this warning message and this scam-type of promotion has nothing to do officially with this company. It is most likely that an affiliate is trying to make easy money by collecting commission after each download made through this fake alert. If you do not want to waste your money unnecessarily, we recommend that you close your browser window and delete Windows Security Warning Popup Scam and all related and unrelated infections from your computer.

As we have mentioned already, it may be a bit tricky to close this fake alert window as it may be opened in full screen mode. You can press the “Esc” or “F11” key to exit the full screen mode and then try to close the window. But it is possible that you can only do so via Task Manager (Ctrl+Shift+Esc) by ending the browser process. Once you close the browser window, we recommend that you reset your browsers and then, check the list of installed programs in Control Panel to find any suspicious program you may have installed lately. In other words, you need to uninstall all adware programs, browser hijackers, and potentially unwanted programs that could be responsible for this fake alert. Please use our guide below if you feel skilled enough to be able to detect such a threat. In order to defend your PC against future malicious attacks, we recommend that you install a reliable anti-malware program like SpyHunter.
