is an unwanted Chrome and Firefox extension that is known for modifying the affected browser and using it as a platform for advertising certain sites. causes automatic page redirects in the browser and spams the screen with ads in order to generate advertising revenue.

The Virus will display pop up ads and messages

This type of applications is actually quite common and many users may have an extension similar to inside their browsers without even realizing it. The thing that sets a regular browser extension apart from one like is the aggressive advertising techniques used by the latter. This is why and other similar applications are referred to as browser hijackers. They take over the browser’s search engine, replace the default homepage, and add new buttons in the toolbar without requesting permission from the user. At first glance, it may seem like these new elements are there in order to benefit the user by providing some new function or a useful online tool. However, it doesn’t take long before people realize that the purpose of the introduced changes is almost entirely advertising-oriented. Any modifications a browser hijacker makes in the browser are almost guaranteed to be part of its advertising agenda. The new search engine will probably redirect your searches to the sites that sponsor the hijacker instead of showing you the information you are actually looking for. The homepage imposed on the browser is likely from one of the sites that is tasked with promoting or maybe the official site of the hijacker. All in all, there’s little to no benefit to be gained from such an app, which is why uninstalling it is the most advisable course of action.

Some security hazards you must know about

The good news if you are faced with is that the app that is currently bothering you is not as dangerous as a virus, Spyware, or a Ransomware infection. The aforementioned are actual harmful computer threats and compared to them the hijacker is more of an inconvenience than an actual danger.

That being said, it is unwise to trust the content put on your screen by the hijacker or to allow this app to keep using your browser as an advertising platform instead of removing it. Something you must understand about this type of apps is that, even though a hijacker would usually not possess harmful abilities, the sites it may promote on your screen could sometimes be unreliable, have a low reputation, or be outright unsafe. The developers of the hijacker aren’t concerned with the quality and the reliability of the websites they promote. All they care about is making money from the paid ads and page redirects. Of course, this means that even if a given site is questionable, illegal, and/or filled with Trojans and Ransomware, as long as it pays a commission to be advertised, the hijacker’s creators will promote it through their app. That is why it is a bad idea to allow the unwanted app to keep spamming you with unverified advertising content and it’s also why we advise you to try out the detailed guide from below and, with its help, uninstall the hijacker from your PC and remove its changes from your browser.

Reboot in Safe Mode (use this guide if you don’t know how to do it).


Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous.

Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Hold together the Start Key and R. Type appwiz.cpl –> OK.

You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

If there are suspicious IPs below “Localhost” – write to us in the comments.

Inside, press CTRL and F together and type the threat’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
