More information on SpyHunter, steps to uninstallEULAThreat Assessment Criteria, and Privacy Policy. is a page-redirecting and ad-generating application that falls into the browser hijacker category. Users who have in their browser may detect unauthorized changes to their homepage and search engine settings and may start to experience redirects to pre-defined websites.

The Virus will display pop up ads and redirect your searches

This strange program can alter the settings of most browsers including Edge, Chrome and Firefox, and can show dozens of pop-up advertisements, banners and notifications on their screen. Normally, as a typical browser hijacker, can take control over the system’s default web browsing app and make certain changes to its settings. For example, it may install some ad-generating components that display sponsored commercial messages during your browsing sessions. It may also replace your search engine with a different one that predominantly shows sponsored search results and set a new homepage address that redirects to a specific site. These new settings typically ensure that you get bombarded with streams of box notifications, pop-ups, banners and other types of online advertising content the moment you open your browser.

The Virus

The automatic web page redirects are another infamous consequence of the presence of the virus inside your browser. This program may reroute you to partnering sites the moment you type a URL in the search bar. This can not only be very annoying but also very risky because you can never know where you may land and what stands behind the websites that get loaded on your browser. The risk of bumping into virus-infected pages, phishing websites and low-quality domains used for the distribution of ransomware, Trojans and other malware is always present. Therefore, some caution is needed when it comes to the activities that a browser hijacker such as the virus can perform.

The Malware

What is probably the most disturbing fact about programs such as the malware is that users often face difficulties when trying to uninstall them and to remove their browser changes. No matter how hard they try, the hijacker’s settings seem to stick to the default web browser in the system and even a change of one browser to another one cannot help eliminate the unwanted software and restore the previous search engine and/or homepage.

That is because programs like typically install some helper elements to facilitate their activity and unless those helper elements are detected and fully removed, the user can’t gain control over their browser. The detection of all the hijacker-related elements, however, normally requires some help from a professional removal tool or detailed guide. That’s why, after this article, we have published a removal guide with a description of the whole uninstallation process of The manual is free and quick to follow but we do advise you to combine it with the automatic removal tool for optimal results.

The reason is that sometimes it is not enough to simply remove the browser hijacker from the system because, by the time you eliminate it, you might have happened to click on some questionable web link or a fake web ad that could have injected some malware (such as ransomware, a Trojan, etc.) or virus into your system that you may not be aware of. And the best way to check your computer for hidden malware is to scan it with a reliable security tool.
