In case that you are browsing the internet regularly you are most probably using a trusted and safe browser to access your favorite sites and other useful information. However, sometimes, out of nowhere, your browser may start to operate differently and may start to flood your screen with nagging ads, sponsored banners, redirect links sudden pop-ups, as well as unwanted modifications to the search engine tool, the toolbar or to the homepage and the new-tab page. Such behavior is normally caused by the presence of a browser hijacker on your system and no browser (it doesn’t matter if you are using Chrome, Mozilla, Internet Explorer, Edge or another popular browsing app) is fully protected from being hijacked. On this page, we will discuss one particular browser hijacker application which is named Thursailso.com. There have been a lot of complaints about this application from a number of users because the strange application has the ability to totally invade the main browser and to change the way it operates without asking for permission. Thursailso.com usually attempts to launch an aggressive online advertising campaign which includes the generation of hard-to-remove pop-up ads, and redirect links which typically appear on every page that you try to visit. The moment it gets installed on the system, the hijacker tends to also change the default homepage with a third-party one or to replace the main search engine with a sponsored one and to install some new toolbars and buttons on the taskbar. Such changes could, naturally, be extremely irritating, especially when they are unwanted and have not been approved by the users. Even more annoying is the fact that they cannot be uninstalled or removed easily, as there is usually no quick uninstall option for that. A simple reinstall of the affected browser is unlikely to get you rid of the hijacker. Changing the main browser will also not help because Thursailso.com may easily get added to it as well. So, what can you do if such an annoying piece of software has taken over your favorite browser? Well, check out the removal guide below to find out.

Could my system get corrupted if Thursailso.com operates on it?

Thursailso.com is not some super dangerous virus or some sort of a nasty Trojan Horse or Ransomware based infection. That’s why there is no reason to get too stressed about its presence on your computer. A browser hijacker like this one is very different from actual dangerous malware and has no intention to do harm to your system. Its purpose is not to corrupt your data or steal your passwords but to make you click on some sponsored ads and visit some partnering third-party websites/platforms. Still, a lot of users seek methods to remove such software because its aggressive ad-generating and page-redirecting activity can cause irritation and unwanted browsing interruptions. Forced to constantly deal with various pop-ups, banners, third-party tools, toolbars, newly installed search engines, and unfamiliar domains, many people find it impossible to browse the web in peace. Another common issue, which the users often report is browser unresponsiveness and sluggishness, which they face while the hijacker operates on their system. All these reasons are usually enough to make someone want to remove such software, even if it is not as dangerous as a Virus, a Trojan Horse or a Ransomware infection.
