This extension contains malware.

This extension contains malware is a potentially unwanted program that security professionals categorize as a browser hijacker. It is typical for This extension contains malware to monitor your web surfing habits and to display different pop-up ads  and banners on your screen during your web browsing sessions.

Another thing that you may notice in case that you have detected that This extension contains malware has attached itself to your Chrome, Safari, Firefox or any other web browser is that now there are some changes in the key settings of the browsing app.  These changes may confuse you since they usually take place without your authorization and normally involve a new homepage, the presence of a new toolbar and also even a new search engine that generates predominantly sponsored search results. What causes even more frustration is the fact that the newly installed browser components cannot be removed and serve no other purpose but to constantly spam you with more and more aggressive pop-up ads, banners and redirect messages. And that happens on every web page that you visit and and even the best add-blocker cannot save you from them.

Other malicious threats that are related to This extension contains malware are: Flash Video Downloader, Stream Video Downloader, MeddleMonkey

All this is because the browser hijackers, which This extension contains malware belongs to, are meant to generate income for their developers through aggressive online advertising.  And the browser changes, as well as the numerous advertisement that they display are all typically sponsored through pay-per-click and pay-per-view remuneration models. Every time you click on a given pop-up ad, banner or a link, or you interact with the sponsored content that the new search engine displays and get redirected to a specific URL, you generate revenue for the people behind the hijacker. Apps like This extension contains malware commonly operate in this way and their entire behavior is dictated by the developers’ strive for more clicks and paid page-redirects and site visits.

 But, for many users, this behavior appears to be very intrusive and highly irritating. That’s why they seek how to uninstall the browser hijacker from their browser in order to get rid of its ads and unwanted homepage and search engine settings. Many people typically try to reinstall their web browsers with the hopes that the hijacker will be removed. Unfortunately, that often isn’t enough to fully eliminate the ad-generating software from the system.

In fact, the developers of apps such as This extension contains malware clearly do not want you to remove their revenue-generating apps. Thus, they usually don’t include an “uninstall” option that allows  for easy removal of the unwanted software. If you want to eliminate the hijacker fully, you will typically need the assistance of a removal guide, such as the one we have published below, or a professional removal tool.

Deleting This extension contains malware is not just about regaining full control of your web browser, though. The browser hijackers are typically linked to a variety of browsing-related issues, even though they are not the same as computer viruses, ransomware or Trojans. Such apps may often redirect you to random web locations and may prompt you to click on different web links, pop-ups and sketchy web ads. Thus, you should always take them with a grant of salt and keep in mind the possibility of facing a real virus or even a nasty ransomware infection if you are not careful with what gets displayed on your screen.
