Virus is a rogue page-redirecting software for Firefox, Chrome, and other popular browsers aimed at turning the browser into a site-promoting platform. If gets attached to your browser, the search engine and the homepage addresses would likely be replaced without your informed permission.

The virus

The changes made to the browser by such browser-hijacking apps are supposed to boost the amount of advertising material that gets shown on your screen while you are browsing. The end goal is to earn revenue on Pay-Per-Click/Pay-Per-View basis from those ads and redirects and so the creators of and Dorputolano have made sure to program their unwanted app to constantly flood your browser with as much promotional content as possible. In addition to being irritating and obstructive, the advertising actions of this browser hijacker could eventually put your whole system at risk of getting attacked by all sorts of harmful viruses and malware programs, including but not limited to Ransomware file-encrypting viruses, Rootkits that will block your antivirus, Trojans that can spy on you and take over the computer, and Phishing viruses that can steal the numbers of your credit/debit cards as well as other sensitive and important information. As you can see, despite not being an inherently harmful app, could still most definitely lead to a number of security issues in the system which is why the suggested thing to do is to uninstall the app at the earliest opportunity.

The Virus

If you think that your browser is currently infected by the virus, then you must first make sure to uninstall the intrusive software. If you have already tried to do that without any significant success, do not despair – it could indeed be difficult to remove such an app from a computer but it’s certainly not impossible. In a guide presented on this page, we will provide you with the instructions needed to get rid of this page-redirecting app and get your browser back to its regular state.

Once you are done with the removal, however, you will also have to look into ways to keep your computer and browser(s) clean in the future. In most cases, users get such apps attached to their browsers not because of some automatic malware infection but because of their carelessness and lack of vigilance. This is actually good news as it means you should be able to keep unwanted browser hijackers away from your computer by simply paying more attention while browsing the web and by avoiding the sites and locations where such apps may be present. One of the most commonly used ways to get hijacker apps installed on the computers of more users is by including the undesirable app as a bonus element inside the installer of another software. Normally, the programs that carry hijackers with them are cheap or free and come from unknown developers. Avoiding downloading stuff from sketchy sites that aren’t developed by a well-known software manufacturer can usually keep hijacker apps away from the computer. However, it is also important to always explore the Advanced setup settings of the apps and programs you install just in case there’s something potentially unwanted added as a bonus component. If you remember to adhere to this safety tip and to use your common sense while on the Internet, you should be able to keep hijackers away from your computer in the future.
