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.

Most add-ons and extensions for browsers such as Chrome, Opera, Edge and Firefox are useful extra elements that could be added to the browser in order to improve its functionality, to make it safer or to add more features to it that it didn’t previously had. However, not all applications that can be made part of your browser are all that useful and some of them might even be unwanted. In today’s article, we will tell you more about a piece of software called “Virus” which might initially seem to be operating as some kind of useful browser extension but after a while it actually reveals that it’s not the most desirable application that you’d want to have on your PC or on your browser. The main issues related to this app are replaced search engine, homepage and unwanted page redirects as well as obnoxious and intrusive ads that pop-up on the user’s screen during each browsing session. Typically, the changes, the redirects and the popping-up ads can’t be stopped by any other way aside from removing their source – “Virus”. Because of all these rather unpleasant traits that this app has been said to possess, most researchers regard this piece of software as a browser hijacker. Browser hijackers are a very widespread category of apps and programs that are all known for similar intrusive behavior. Although some of the might still offer the end-users some kinds of functionality and helpful features, in the majority of cases the irritation caused by such apps is too much for any user to tolerate which is why most customers tend to prefer to get rid of such hijackers as soon as they find out about their presence on the computer. With this in mind, we have decided to put together a guide that will help those of you who have on their machines have it fully removed and uninstalled. The guide will also show you how you can return your browser back to normal so that the unwanted changes made to it are no longer present. Know, however, that if you feel like the manual steps from the guide are too advanced for your computing skills, you can also try out the suggested removal tool that has been added to the guide. Generally, it’s best if you make use of both removal methods so as to be sure that there’s really nothing unwanted left on your machine. In addition to all that, the comment section down below is available to any of you who might want to directly ask us a question about the nature and removal of or anyone who’d simply like to share their opinion on the topic. “Virus” Removal

Danger level

Many of you might be concerned about having some unwanted app on your machines thinking that it is some kind of insidious virus. However, if you are dealing with nothing more than a hijacker app, then you have no reason to be overly-worried. Hijackers, despite being some of the most annoying apps out there, are mostly harmless. isn’t some nasty and dangerous virus like a Ransomware or a Trojan Horse – it is simply an app that is supposed to aggressively advertise something on your screen in hopes that you’d click on it and maybe buy the promoted product. In spore of this being really frustrating and unpleasant, it doesn’t pose a direct threat to your PC. However, if you don’t remember to stay careful and watchful, your machine might still get exposed to more serious danger due to the hijacker’s advertising activities. We strongly recommend you do not click on any ads and redirects caused by the hijacker as they might sometimes be leading to online locations with questionable reputation and if you land on one such location, then you might indeed have your machine attacked by some nasty Trojan or Ransomware virus.

Be careful about file-bundles

A lot of programs out there have other applications added to them as optional installs in which case a file bundle is formed. This technique is oftentimes used for distributing unwanted apps like The undesirable software is added to the bundle and if the user isn’t vigilant enough and doesn’t opt out of the installation of the extra software, they’d get it installed on their PC alongside the main program from the bundle. You can, however, prevent this from happening in future by going to the advanced setup menu and unchecking the checkboxes next to any optional/bundled apps that you might not want to have on your computer. This is indeed what we’d advise you to do in future so as to avoid any more encounters with intrusive apps like
