MainCaptchaNow.top is a browse-redirecting and site-promoting tool that changes the settings of the users’ browsers without permission and causes the generation of obstructive ads. MainCaptchaNow.top also frequently page-redirects the browsers to various sites, some of which may not be safe.
Our goal within the next lines will be to help you deal with an annoying software component for browsers like Chrome and Firefox by removing it from your system in case it is causing disruptions while you are browsing the Internet. Some of the “abilities” of this app is to redirect the users to various pages on the Internet and to show ads in their browsers. Additionally, it may install a new search engine service in the browser, replacing the previous one, as well as change the address of the homepage and the address of the new-tab page. It is likely that these changes would be advertised as useful for the user. In fact, MainCaptchaNow.top is probably going to be promoted as a useful add-on for the browser that would make one’s web experience more pleasant and safer. However, one thing to note here is that the changes may be quite invasive and you may not be able to opt-out of them or to cancel them once they have been imposed unless MainCaptchaNow.top gets uninstalled. Also, the random popping-up of ads, banners and page-redirects on your screen while you are trying to find something on the Internet could also be quite irritating, to say the least. Not to mention that the new search engine or the homepage that has been set as default on your browser by the annoying app are likely not going to be anywhere as useful as advertised. In fact, they may make it quite more difficult for you to actually find what you are looking for on the Internet. All of this leads us to the conclusion that MainCaptchaNow.top, Fast Captcha, Main Captcha Top and Main Captcha Now Top, are nothing more than another representatives of the well-known category of potentially unwanted software known as browser hijackers. In case you’d like to find help with removing the hijacker, you can find it in the following list of instructions.
One more thing…
A very important aspect regarding the apps of the browser hijacker category like MainCaptchaNow.top is that, while they are not as dangerous as Trojans, Ransomware and other similar infections, they are not software that we would advise you to put your trust it. The issue here is that you won’t really have a say in what advertising and commercial content gets brought to your screen by the hijacker. Usually, such apps try to access your browser history and cookies and determine what ads you may be interested in but there’s nothing to say that the algorithm of the hijacker won’t determine that you need to be presented with ads from unreliable sources. And if this happens and you click on some sketchy ad that is linked to a dangerous site, you could get all kinds of nasty infections and malware in your computer. We already mentioned the Ransomware and the Trojan Horse threats but you should know that these are only two examples of the many malware programs that you could encounter if you are not careful with what content you interact with while online.
Some threats reinstall themselves if you don't delete their core files. We recommend downloading SpyHunter to remove harmful programs for you. This may save you hours and ensure you don't harm your system by deleting the wrong files.
