This page aims to help you remove Strialdeather.info. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Strialdeather.info is an application, which is not malicious and is not expected to harm your PC and/or target your files like a Trojan Horse or a Ransomware virus would. However, it isn’t an application that you would like to keep on your system either as it is likely to try to tinker with your browser’s starting page, search engine and toolbar settings and spam your screen with ads, page redirect tabs and other intrusive advertising content. All of this is because Strialdeather.info operates as a browser hijacker for some of the most popular browsers like Chrome, Edge and Firefox and is programmed to display various types of sponsored advertising content on your browser screen for as long as it remains on the computer. You may come across this piece of software almost anywhere on the web because it is commonly distributed via free download links, email attachments, browser add-on installers, different games, torrents, optimization tools and mostly via software bundling. It is very easy to spot the hijacker because, unlike the real virus threats, it doesn’t try to remain unnoticed in the system and instead immediately latches onto your main browser and forces it to generate many of pop-ups, pay-per-click ads, banners and automatic page-redirects during your browsing sessions. Another annoying thing this advertising software may do is change your homepage or search engine with a sponsored one and to install some new toolbars and new tab page without your approval. This would have not been such a problem if there was an option to easily uninstall the new components or at least those that you find as unwanted, and still use your browser as before. But the most annoying thing is that even if you try to remove the browser changes, or even reinstall the browser, Strialdeather.info has the ability to get incorporated again, the very next time you start a new browsing session. The instructions and the automatic malware-removal tool below, however, can help you make all of this go away.

Is it dangerous to keep a browser hijacker like Strialdeather.info on your computer?

The activities conducted by the browser hijacker application are normally regarded as highly irritating by a lot of users. And this is not surprising because the potentially unwanted changes to the browser combined with the constant ad interruptions and page-redirects have the potential to really decrease the overall web surfing experience that you have. Many people, however, are more concerned about the reliability of the displayed content and the possible encounters with hidden malware (such as Trojans, Spyware or Ransomware) somewhere, in the random flow of pop-up ads. Now, we have to mention that infecting you with viruses is not the aim of the browser hijacking software. Yet, unfortunately, such a risk exists when you are constantly getting exposed to some unfamiliar links, sites and ads from third-parties. That’s why, although it is very unlikely for Strialdeather.info to cause any direct damage to your system, it is preferable if you refrain from interacting with its content and consider how to permanently remove the pop-ups and uninstall the unwanted browser components.  

SUMMARY:

Name Strialdeather.info
Type  Browser Hijacker

Symptoms  Annoying ads and automatic page-redirects may interrupt your web surfing. 
Distribution Method You may install this program when performing careless installation of software bundles, automatic installations, or when downloading spam, free browser ad-ons, torrents.
