You have some new homepage that you do not recognize and the default search engine of the browser that you used to have has been replaced with some custom one that always seems to favor pages full of aggressive ads, pop-ups, banners and page-redirect links. A strange program called Shetrius is what’s probably responsible for these changes and is the reason behind the browsing annoyance you are now faced with.

The Shetrius Virus

The Shetrius virus, classified as a browser hijacker, often infiltrates computers bundled with other software. Once installed, it alters homepage settings and default search engines, alongside engaging in automatic page-redirects and inundating screens with sponsored ads, pop-ups, banners, and promotional messages. Typically, browser hijackers like The Shetrius virus and modify browser configurations, imposing unwanted changes that disrupt user experiences and inundate screens with intrusive content. While not as severe as traditional viruses, these hijackers negatively impact browsing sessions, causing disturbances and redirects that interfere with regular online activities. Users encountering The Shetrius virus may notice unauthorized modifications to their browsing settings and an influx of unsolicited advertisements, prompting them to seek removal solutions to restore a smoother, uninterrupted browsing experience.

What is Shetrius?

Shetrius, a browser hijacker, doesn’t pose serious data theft risks or direct dangers to computers. However, may redirect users to pages hosting genuine security threats like viruses, Ransomware, Trojans, and various malware. While Shetrius itself doesn’t steal data, its redirects potentially expose users to hazardous online locations, increasing the risk of encountering severe malware. Despite not directly causing harm, it’s redirect behavior puts users at risk of inadvertently accessing sites hosting harmful viruses and malware. Users encountering such app on their systems should exercise caution to avoid the redirected pages and consider removing this browser hijacker to prevent exposure to potential security hazards lurking in these redirected locations.

Shetrius Pop-ups

Shetrius pop-ups, common among browser hijackers, flood screens with pay-per-click ads or tweak the Windows registry to reset browser settings at every computer restart. The primary aim of these hijackers is to garner more clicks on their advertising pages, bombarding regular web browsing with paid promotional messages. For users averse to aggressive online advertising, removing Shetrius pop-ups becomes imperative to permanently eradicate these intrusive ads. These unwanted pop-ups disrupt browsing experiences significantly, prompting users to seek solutions to uninstall Shetrius and eliminate its pervasive advertising strategies, ensuring a smoother and uninterrupted online browsing session.Removing Shetrius pop-ups involves steps to effectively eliminate these intrusive ads from your browsing experience. You can start by accessing your browser settings and reviewing installed extensions or add-ons, removing any suspicious or unfamiliar ones linked to Shetrius.

Shetrius on Chrome

There are several ways in which you can land a Browser Hijacker like Shetrius. One of them is when you open email messages which contain files that prompt you to install an application for free. In many cases, the hijackers are bundled in free download packages or along  some other useful and attractive apps. The reality is that the vast majority of sites that offer free downloads resort to download managers that contain browser hijackers and similar ad-generating software along with the main programs they install. Therefore, there is a great chance of installing a piece like Shetrius by default or as a “bonus” component added to the free program.

This is especially likely to happen if you don’t specifically customize the installation settings so as to exclude the bonus elements. Therefore, to avoid the installation of potentially unwanted programs, always read the terms of use and the privacy policy of the downloaded programs, do not click on pop-up ads, discard the installation of packaged browser extensions and, in the case of installing a free program, resort to the custom installation instead of using the default one. To uninstall and remove its changes so that you don’t get accidentally redirected to a site with Trojans or Ransomware in them, please follow the instructions below.

Step1 Uninstall the Shetrius app and kill its processes

The first thing you must try to do is look for any sketchy installs on your computer and uninstall anything you think may come from Shetrius. After that, you’ll also need to get rid of any processes that may be related to the unwanted app by searching for them in the Task Manager.

Note that sometimes an app, especially a rogue one, may ask you to install something else or keep some of its data (such as settings files) on your PC – never agree to that when trying to delete a potentially rogue software. You need to make sure that everything is removed from your PC to get rid of the malware. Also, if you aren’t allowed to go through with the uninstallation, proceed with the guide, and try again after you’ve completed everything else.

  • Uninstalling the rogue app
  • Killing any rogue processes

Type Apps & Features in the Start Menu, open the first result, sort the list of apps by date, and look for suspicious recently installed entries.

Click on anything you think could be linked to Shetrius, then select uninstall, and follow the prompts to delete the app.
