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.

Welcome to this page where we will help you to get rid of some annoying page-redirects, pop-ups and intrusive ads, which might have recently started to appear in your Chrome, Firefox or Explorer browser. Normally, such aggressive ad interruptions tend to appear due to the presence of a browser hijacker such as “Virus” on the system. This type of software is very commonly encountered and is usually accused of making unauthorized changes to the default browser (homepage or search engine replacements, installation of new toolbars, page-redirects, etc.) and the way it operates. Luckily, these are not virus-inflicted changes to be afraid of but a rather aggressive online advertising method, implemented by applications like “Virus”, which ensures that certain sponsored tools, toolbars, search engines, homepages or websites get exposure and get visited by the web users during their regular web surfing. “Virus”

In the next lines, you can learn more about the purpose and the characteristics of “Virus” and the browser hijackers in general as well as about the best methods that you could use to have them uninstalled. To your relief, such pieces of software are much easier to deal with compared to the nasty viruses and security threats (Trojans, Ransomware, Spyware, etc.) that we often discuss on this website. Most of the web users should usually be able to handle the hijackers without professional assistance if they follow certain removal steps. In fact, a removal guide like the one below might be more than enough to help you take care of a hijacker that is nagging you and messing with your browser. It can show you how to locate and remove the undesired changes which the hijacker may have placed to your browser as well as their related files. If you are not sure how to handle the manual instructions, however, there is no need to feel helpless. You can always use a specialized removal tool of your choice which can scan your system and uninstall in such a way so that it will never bother you again. For optimal results, it is a good idea to use a combination of both in order to effectively deal with the undesired software and bring your favorite browser’s regular settings back to normal.

Does aim to harm the PC?

When a browser hijacker operates on the system, it typically makes some changes to the default browser without asking for approval. This software is basically programmed to operate this way. It basically serves the purpose of its creators, which is to generate revenue from Pay-Per-Click ads, paid promotions’ positioning and sponsored page-redirects. In order to do that more effectively, a hijacker application such as can replace your preferred homepage with another one, install a sponsored search engine or set some promoted toolbar which may start to automatically redirect you to specific predefined web pages, ads, offers, paid links and promotional banners. According to the law, this is yet another form of online advertising, which can expose the users to different commercials during their regular web surfing, and is normally not deemed illegal. The people who have to deal with it, however, may face issues while trying to use the hijacked browser and may not be able to surf the web without constantly getting interrupted by pop-ups, banners and page-redirects. That’s why it is not surprising that the presence of the browser hijackers on the system is often regarded as potentially unwanted and why most  number of the users who are faced with such software seek fast and effective ways to have it uninstalled. Many of them actually fear that such software may expose them to potentially hazardous web content such as misleading links, fake ads and infected web pages, which could be transmitters of viruses as nasty as Trojans, Ransomware or Spyware. This, in fact, is a reasonable concern because there is no way to have control over all the attractive pop-ups and automatic page-redirects that the hijacker may generate and, in theory, nothing can stop a well-camouflaged infection to sneak in the ads streaming on your screen. That’s why it is wiser to avoid interaction with the randomly popping-up messages and use the instructions in the removal guide or a specialized removal tool to remove and uninstall its changes from your browser.

Keep in mind, though, that if you don’t stay away from the potential transmitters of browser hijackers, you may land yourself with another one soon. That’s why, once you remove the undesired application, do not forget to pay attention to your system’s safety and try to avoid any sketchy web locations which could deliver potentially unwanted apps in your PC. These could be the numerous free download links on the web, different ad-supported sites, torrents, shareware or freeware platforms, spam messages, email attachments and some free software bundles or browser add-ons. If you really have to download and install something new on your computer from such sources, pay close attention to the Advanced/Custom installation settings and do not hesitate to leave behind any additional or potentially unwanted component by manually unchecking it from within the installer.
