The current article is dedicated to a recently reported browser hijacker called can take over your main browsing app and cause it to generate ads during your browsing sessions.
The virus will display pop up ads and messages


If you are on this page due to the fact that Windowsdetector has mysteriously taken over your Chrome, Firefox, Explorer or any other browser that you are using – stay with us. We will tell you exactly how to remove the Windowsdetector and uninstall all the nagging changes that it might have imposed on your machine.

Namely, these could be related to replacements in your browser’s homepage or search engine tool, installation of new buttons, toolbars and new-tab links and the unstoppable generation of hundreds of ads, banners, and pop-ups. Many users may experience difficulty to browse the web while is operating in their system mostly because the program tends to initiate automatic redirects to pre-defined websites and to fill the screen with sponsored ads that constantly prompt them to click on various offers.

Another thing that tends to create a lot of panic and confuses people is the fact that when they try to remove the ads from the screen or to uninstall the imposed changes, they get re-installed again. Thus, every time you re-open your browser, you are greeted by the same sponsored homepage, search engine, buttons and ads. This alone is enough to make some users believe that they have been infected by some nagging virus or malware (probably ransomware or some stealthy Trojan) that doesn’t want to go away. However, to your relief, this is not the case with browser hijackers. These pieces of software can be nagging, but they are not malicious and in the removal guide below we will show you how to quickly deal with them.

Programs like, Good Captcha Style, iStart Search Bar are nothing more than advertising tools that serve the interests of the online marketing industry. They are programmed to generate a massive amount of online promotional materials, such as banners, pop-ups, redirect links and pay-per-click ads, during your regular web surfing and to prompt you to visit specific pages. But what for?

Well, browser hijackers are essentially the result of business collaboration between software developers and manufacturers or distributors of different products, services, and websites. These programs serve as a medium that promotes specific advertising messages directly on the users’ monitor for a fee, which is usually calculated on a pay-per-click basis. The more people click on the displayed ads and sponsored messages, the more traffic and exposure the advertisers get and, respectively, the more profits the program generates for its developers.

This seems to be a lucrative method which does not cause direct harm to the system but sometimes can allow room for some rather unpleasant marketing tactics such as automatic redirects, sponsored browser changes, and excessive exposure to commercial content during web browsing. In some instances, the activity of the browser hijacker may also contribute to accidental encounters with security hazards, (such as real viruses like ransomware and Trojan horses) namely because it may redirect the users to various unfamiliar web locations. For this reason, it is generally advisable to keep away from the click prompts that programs like may display or better, get rid of them permanently.
