Is there a way to stop your Internet Explorer, Chrome, Firefox or another browsing program that you might be using from spamming your screen with various aggressive ads, pop-ups, banners and annoying page-redirects? If this is the question that brought you to this page, then we might be able to help. The most probable reason for the ads invasion that might be happening on your monitor is not the infection with some sort of a nasty Ransomware or Trojan Horse-based virus, but the presence of a browser hijacker such as “System Warning: Your Windows System is Damaged” on your default browser. You can easily spot such software because, the very moment it gets installed, it usually makes some changes to your default homepage, toolbar or search engine right away. It also starts to generate “Ads delivered by “System Warning: Your Windows System is Damaged”” all over your screen, regardless of whether you have an add-blocker or not. In the next lines, you can learn what else such a browser hijacker could do and how to safely remove its ads and uninstall its changes without causing harm to your system. Our “How to remove” team has prepared a detailed removal guide on that, but if you prefer to get rid of the nagging pop-ups and page-redirects immediately and without the need to tinker with your system, you can use the suggested “System Warning: Your Windows System is Damaged” removal tool available below and eliminate the browser hijacker in just a few clicks.

Luckily, most browser hijackers are fairly easy to deal with because they do not belong to any malware category. Such pieces of software are created simply to advertise and to earn pay-per-click revenue from sponsored positioning of ads, tools, search engines, homepage domains and paid redirects. But the methods that they usually use in order to promote their sponsored content can oftentimes frustrate the majority of users. That’s why many people seek methods to uninstall the hijacker and save themselves from the aggressive marketing campaigns that are running on their screen.

Security issues you should be aware of

Despite not being as malicious as a Ransomware, a Spyware or another type of a nasty computer virus, a browser hijacker is still one of those apps that you most probably won’t want to keep on your computer. And the frequent ad displays and the uncalled for browser changes are not the only reasons for that. In the majority of the cases, during the time it operates on the system, this software is unlikely to provide you with any useful functionality which may be worth it to endure the frequent pop-up interruptions and automatic page-redirects. More often than not, however, you may have to face browser unresponsiveness, freezing of the screen, sluggishness and overall web surfing disturbances, which may greatly reduce the quality of the time you spend online. Another disturbing fact might be that the origin and the reliability of all the nagging banners, offers and links may also not be confirmed. This means that the software may not display both legitimate redirects and ads but also infected content, which might hide malicious threats from the ranks of Trojans or Ransomware. That’s why it might not be a good idea to click on and visit everything which the hijacker may prompt you to interact with.
