How irritating is this problem? (1 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.

If a browser hijacker has infiltrated your Chrome, IE, Firefox or any other browser that’s on your PC, then you’d probably want to remove the hijacker due to the irritating effects it’s likely to have on your browser. What we mean by that is the hijacker will probably try to fill your browser with an endless stream of ads, banners, pop-ups, box messages, blinking windows, page redirects and other similar intrusive forms of advertisement. In addition, you might have your browser’s default homepage and search engine replaced with new ones that the hijacker has added to your browser without your permission. Such activities are likely to make your browsing experience highly irritating and unpleasant. Aside from that, the random ads coming from all kinds of sources might, at times, expose your machine to potential hazards like viruses such as Ransomware and Trojan Horses. Due to all that, it’s typical for hijacker apps to be regarded as potentially unwanted. Understandably, most users would prefer to get rid of any hijacker that might have founds its way inside their systems. However, removing such a software piece might not be as easy as uninstalling a regular program. First of all, oftentimes there isn’t a built in way of uninstalling a hijacker. Most such apps have no uninstallation manager or an uninstallation entry in the list of programs within the Control Panel. In addition, if you try to simply remove/disable the app from within your browser’s extensions manager, it’s likely going to come back the next time you open a browsing session. All of this makes it rather tricky to successfully and fully eliminate a hijacker app. However, as long as you know what you are doing and where to look for the hijacker’s date within your PC, you should have no problem doing away with the irritating piece of software. All the information that you’d need in order to get rid of a hijacker app has been provided for you down below, inside our removal guide. We have given an example with “Virus”, which is one of the latest and most annoying hijacker apps out there. If you presently have “Virus” in your system, we advise you to carefully read the rest of this write up and then head down to our guide and use it to eradicate the pesky software component from your PC and your browser. In case you feel like the instructions from the guide are too complicated or not clear enough, you can always request our help by using the comments section and you can also try the recommended removal tool which is yet another good method of getting rid of “Virus”. “Virus” Removal

What are browser hijackers?

Unlike what many of you might think, a browser hijacker isn’t some scary and insidious virus like a Ransomware or a Trojan. Hijackers are mostly advertising-oriented and their main goal is to make profits for their creators through conducting aggressive advertising campaigns. This means that an app like will likely not try to inflict any damage on your PC, it will simply spam you with ads and use the modifications it has imposed on your browser to facilitate its advertising campaigns by showing you modified search results and redirecting you to promoted pages. Again, none of this should be directly harmful to your computer. However, since the source network of the generated ads might not always be a reliable on, there’s some chance you might end up landing on shady and hazardous web locations where all kinds of virus programs like Spyware, Rootkits, Trojans and Ransomware might lurk. Because of this, it is always preferable to keep your machine safe by staying away from ads generated by a hijacker. Also, the best way to ensure the security of your computer would be to simply uninstall the unwanted app which is what we’d advise you to do as soon as you finish reading this write-up.

The distribution methods used to spread browser hijackers

There are many different ways such an app can find is way to your computer. Spam messages with attached links or files, fake and misleading online adverts generated by unreliable sites, shady and/or pirated downloadables, etc. Many customers also get apps like installed on their machines after installing some other program with which program the hijacker has been bundled. The good news is that, as long as you pay attention to the setup menu, you should be able to easily leave out the unwanted app from the installation process by unchecking it from the menu. Just remember that sometimes you might need to use the Advanced/Manual setup option in order to do that.
