How irritating is this problem? (3 votes, average: 5.00)

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

No user enjoys when their browsing sessions are getting interrupted by adverts that try to prompt you to click on them and that wouldn’t go away unless you open them and see what they are about. It’s only natural, though, since, after all, the advertising business is one of the most profitable ones and everybody wants to have a piece of the cake. So, it is understandable why so many sites and pages try to spam your screen with all kinds of intrusive advertising materials like banners, pop-ups, blinking boxes, flashy box messages and so on and so forth. However, the problem comes when the ads and the page redirects keep appearing on your Firefox or Chrome (or some other) browser and also when you realize that certain elements of your browser have been altered (such as the homepage address and the search engine tool) in favor of some sponsored components that also try to promote something. For instance, you might have recently had a new search engine imposed on your browser that has replaced your previous one and which is currently showing you modified results that try to push and advertise certain online addresses that you don’t really want to visit. All of this, and much more, is what you can expect if a browser hijacker application has gotten installed on your computer. Browser hijackers are infamous online advertising software components that can be added to pretty much any browser that the user might have and that tend to alter certain elements of the browser as well as spam it with different adverts and redirects to promoted pages and sites. Understandably, most software specialists as well as the majority of the regular users regard the representatives of this software category as potentially unwanted. In fact, browser hijackers are oftentimes referred to as viruses and malware. Now, if you have a hijacker on your machine, do not worry as it is much less harmful than a virus threat such as a Trojan Horse or a Ransomware. However, it is still a quite irritating app to have on your computer which is why we advise you to remove it. A guide has been posted just below to help our readers eliminate the so-called – this is a hijacker app that is quite widespread nowadays and many users seem to have problems with it. “Virus” Removal

The characteristics of and of hijackers in general

It should be rather obvious that the main goal of as well as the main goal of the majority of the other software pieces that can be categorized as browser hijackers is to advertise stuff from inside the users’ browsers. This is understandable since each click on each ad generates money for the people behind the hijacker. This is why the advertising campaigns conducted by apps like tend to be so intrusive and aggressive and why the developers of browser hijackers typically seek to get their software installed onto as many machines as possible.

Still, as we said, this type of apps are not real viruses – they wouldn’t normally target and try to damage anything on your system or acquire some sensitive data from your machine and later use it to blackmail you. These are the kind of activities that infections like Ransomware, Trojans, Spyware and Worms would conduct and are not typical for hijackers. That said, since the adverts you see on the Internet can’t always be trusted and since an app such as is known for flooding the users’ screens with a lot of online advertisements, it’s still better to see to the removal of the potentially unwanted piece of software before it has redirected (albeit, not purposefully) to some shady and hazardous web location.

The protection of your PC should come first!

We understand that you might be tempted to explore the Internet and go to sites that might not necessarily be reliable or safe. However, hijackers really are only the tip of the iceberg when it comes to what types of unwanted and potentially dangerous software you might encounter on the Internet. That is why, it is important to keep a safe distance from anything that might be questionable – spam messages, sites that distribute pirated programs, sketchy-looking adverts and offers and so on. Another really important (and oftentimes disregarded) safety rule is to always be aware of what you are about to install on your PC. Many programs have extra components added to their installers and sometimes, such a component might be a hijacker. That is why it is essential to never simply “spam” the Next button until the program is installed and instead take a more careful look at the installation details and maybe even visit the Advanced setup menu so that you could see if there are any added components which you might not want and leave them out of the installation process if you think that this is the reasonable thing to do.
