This page aims to help you remove Advisurf. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

There are many web locations where you may come across applications like Advisurf. These pieces of software are very widespread all over the Internet because they operate as aggressive online advertising tools and serve the needs of the online marketing industry. In order to advertise more effectively, Advisurf and other similar software components tend to hijack the users’ default browser (it could be Chrome, Firefox, Explorer, Opera, etc.) and force it to display various pop-ups, promotional links, ads, banners, new tabs or sponsored offers. Most of the people who end up with such software on their PC complain about a never-ending stream of ads on their screen as well as some automatic page redirects and potentially unwanted changes to their default search engine or homepage domain. Generally, these are not harmful activities but they are typical for one software category known as browser hijackers. What exactly a browser hijacker is and what it can do to your system is what we will discuss thoroughly in the next lines. So, if you have recently started getting disturbed by Advisurf or similar browser-hijacking piece of software, it might be a good idea to stay with us and read the information that follows. A step-by-step Removal Guide has been published right below and you may need it in order to uninstall the undesired application and remove its changes from your PC. There is also a professional removal tool down below which can automatically deal with the annoying browser hijacker without any risk for your system. Before you use them, however, we suggest you familiarize yourself with the specifics of the ad-producing software and learn about its danger level and typical methods of distribution.

Is Advisurf a computer virus?

The Internet is full of various computer threats – Ransomware, Spyware, Trojans and many other nasty viruses that are lurking throughout the shadier corners of the online world. Advisurf, however, is not a representative of any malware category. This application is a browser hijacker – a type of software which is specifically created to advertise certain products, services, web pages and tools on the users’ screen during their web surfing. There is nothing harmful or criminal in this type of software and unlike the real computer viruses, its aim isn’t to corrupt your PC, to steal your data or to involve you in some sort of a cyber crimes.

Most of the web users oftentimes confuse the browser hijackers with some sort of a nasty infection because they tend to behave a quite aggressively. Usually, the moment they become part of the system, these applications tend to irritate you and interrupt your normal web browsing with various pay-per-click ads, pop-ups, banners of different shapes and colors and some sponsored page-redirects. The online advertising industry benefits from this activity since the ads generate traffic and exposure to certain items that need to be promoted. Most of the web users, however, may feel rather disrupted and irritated by the hijacker’s activity because the quality of their normal web experience may get significantly decreased due to the constant pop-up interruptions, the exposure to unfamiliar web locations and due to some strange browser changes. Of course, the side effects of having a browser hijacker on the system could not be compared to the harmful attack of a Ransomware cryptovirus or a nasty Trojan infection, but they could still be seen as potentially unwanted. If dealing with ads during each browsing session is not something that you could tolerate, we would suggest you use the instructions in the Removal Guide and have Advisurf uninstalled from your system. This will save you from all of its annoying activities and undesired browser changes in a safe and reliable manner.

How to stay away from browser hijackers in the future?

As we said above, usually a browser hijacker cannot sneak inside your system and infect you in the same way that a virus program could. However, you may install such software without actually realizing it and this is very likely to happen if you don’t pay close attention to certain setup settings when about to install a new program. Thanks to a popular method know as software bundling, applications like Advisurf may get downloaded and become part of your system along with some other interesting application, free browser component or a software update. That’s why, if you run a new setup on your PC, we advise you to opt for the Advanced or the Custom installation settings and carefully check for any added or recommended bonus applications which may be bundled there. Simply disable them from the menu that will open and you won’t have to uninstall them later.
