Sudden page-redirects, different intrusive adverts on your screen, changes in your homepage URL or search engine are some of the most common symptoms which can indicate that a browser hijacker has been installed on your system. This type of software is usually similar to browser extensions and can be encountered on popular browsers like Chrome, Firefox, Edge, Safari, and others. Many users end up with browser hijackers when they perform a quick or automatic installation of application bundles, different free apps, add-ons and updates which are the most common sources of additional and free browser-hijacker components inside their setup settings. Luckily, these pieces of software do not have any particular harmful abilities and that’s why they are not considered to be as dangerous as Trojans, Ransomware, Rootkits, computer viruses or similar malicious threats. Still, many web users and security experts refer to the browser hijackers as potentially unwanted due to their aggressive ad-generating and page-redirecting behavior. Within the next paragraphs, you can learn more about the purpose of these pieces of software and the potential problems you may have with them as well as about the best methods that you can use to safely remove them. In fact, in the removal guide below, we will describe the uninstallation steps of one recently reported hijacker-based application called Thursailso.com.

Why is Thursailso.com bombarding you with ads?

Generally, the reason browser hijacker apps such as Thursailso.com exist is to generate revenue for their owners through different aggressive (yet still legal) marketing campaigns. Such applications are programmed to fill your screen with various ads, offers, sponsored tools, toolbars, search engines and domains, which, once clicked upon, earn pay-per-click or pay-per-view income. Usually, there is nothing harmful or criminal in such an advertising approach and that is why the hijacking software is not considered to be any serious computer danger. However, trusting everything a potentially unwanted browser component like Thursailso.com may display is not a good idea in general. The reason is, the ad-generating application may oftentimes load adverts or links with unverified origin. It is not excluded that you may be prompted to purchase goods or services with questionable quality or to provide personal details on some sketchy platforms. A danger may also come from the automatic redirects that the hijacker may initiate. Without having control over your browser and over your search engine or homepage, you may land on unfamiliar sites or different risky platforms where real computer dangers (like Trojans, Ransomware and other viruses) may hide. For this reason, we consider the uninstallation of Thursailso.com to be highly advisable and suggest that you use the instructions above to remove its ads and browser changes permanently.
