“Browser” Extension Virus

“Browser” Extension

“Browser” Extension is a potentially unwanted program that falls into the category of browser hijackers. As such, “Browser” Extension has the capacity to meddle with the settings of your browser and impose certain changes.

Browser Extension Virus

For instances, it will likely introduce its own search engine which will substitute the one you had set by default. That same search engine, or possibly a different site, will likely be set as the new browser homepage as well. And if you try to reverse these changes in the settings, the next time you start your browser it will only be to find that the settings imposed by “Browser” Extension are back in place. This is because as long as this program exists on your computer, it will always be in charge of your browser. The only possible way to rid yourself of these unwanted effects is by removing the browser hijacker in question.

The only tricky thing about that is that, unlike most other types of software, programs like “Browser” Extension, Captchafair.top, iStart Search Bar don’t exactly offer an obvious uninstallation option. In order to ensure that this hijacker is permanently and completely gone from your PC, you will have to dig a little deeper into your system. And we can show you exactly how to do that in the removal guide that you will find just below this post.

  • Go to the browser menu again, select Options, and then click on Home from the sidebar to the left.

  • If you don’t see a “”Browser” Extension” process in the Task Manager, look for another suspicious process with an unusual name. It is likely that the unwanted process would be using lots of RAM and CPU so pay attention to the number of resources each process is using.
  • Tip: If you think you have singled out the unwanted process but are not sure, it’s always a good idea to search for information about it on the Internet – this should give you a general idea if the process is a legitimate one from a regular program or from your OS or if it is indeed likely linked to the adware.
  • If you find another suspicious process, open its File Location too.
  • Once in the File Location folder for the suspicious process, start testing all of the files that are stored there by dragging them to our free online scanner available below.

If all files get deleted normally, exit the folder and delete that folder too.

    What is the purpose of “Browser” Extension?


    You might be wondering what the point of all these changes is. In addition to the above, browser hijackers like “Browser” Extension also specialize in generating various online ads directly within your browsing program. Thus, all sorts of popups, banners, box messages and other advertising materials will be present on more or less any website or page that you visit.
    And the point of it all is for the developers of these programs to earn commission from all these paid ads. Normally this happens as part of Pay Per Click and Pay Per View remuneration schemes, which means that every click and/or view on said ads generates revenue for the browser hijacker creators. This is why the ads are usually positioned on your screen in a way that makes it almost impossible to avoid interacting with them.
    In addition to the aggressive positioning, though, programs like “Browser” Extension also tend to engage in certain questionable background practices. For instance, browser hijackers have been known to gather browsing-related data from users in order to optimize the ads they display. This data is stored and analyzed, but can later also be sold to third parties – and all of this without necessarily obtaining the user’s informed consent.
    Furthermore, the frequent page redirects that programs of this type trigger can potentially pose a security risk for your system. There is a danger of landing on a site or page that may be harboring viruses and malware like Trojans, spyware, ransomware, etc. The same could even go for the ads displayed on your screen, so be very careful with what you click on as you’re browsing the web. But of course the best way to minimize your risk of a virus infection is  to delete “Browser” Extension.
