Regardless of the issues you might be having with your computer, the first and most important step towards solving them is to understand what exactly is causing the problem. Sometimes, it could be a virus or a malware infection such as a Ransomware or a Trojan Horse, while in other cases, it could be just the presence of a potentially unwanted application such as on your computer that is swarming your browser with page-redirects and ads and is also trying to enforce a new search engine tool or a new homepage URL. In this article, we will tell you more about this particular application and its effects on your machine as well as about the most effective ways to safely remove. is what is known as a browser hijacker and could be a common source of browsing-related disturbances if it gets inside your Chrome, Firefox or Explorer browser. In such a case, you are very likely to experience a stream of unpleasant and aggressive advertising materials (such as ads, pop-ups, banners, automatic redirects, etc.) which may interrupt your regular web surfing activities. Such an application may basically turn your main browsing app into an ad-generating and page-redirecting tool, which may constantly prompt you to click on some third-party links, sponsored ads, pay-per-click messages and similar commercial content. In order to do that, typically makes some changes to your default search engine or homepage URL by replacing them with some sponsored ones. Many users initially think that they must have been attacked by some virus, which has probably made these changes and don’t even realize that the software they are dealing with is actually a browser hijacker. In the next lines, however, we will show you exactly how to end the annoying ad interruptions and, most importantly, how to safely uninstall the hijacker and remove all of its browser changes. For optimal and quick uninstallation, we suggest you use the instructions in the removal guide below as well as the professional removal tool attached to the guide.

Don’t trust all the nagging ads and commercial messages!

As you probably know, not everything that gets posted on the web is safe and reliable. The same applies to the ads and the commercial messages that you get exposed to on a daily basis. You never know when you may come across misleading or infected links or messages and with a browser hijacker such as in your browser, the number of random commercials, pop-ups and redirect links you get exposed to greatly increases. This naturally increases the chances of clicking on something hazardous or running into some insecure web locations where nasty Trojan Horses, Ransomware or Spyware threats may lurk. Now, such things don’t happen that often, but let’s face it, the less spam and unfamiliar adverts that come your way, the greater the chances of avoiding any close encounters with computer hazards and to remain safe. In this regard, the best way to stop from spamming your screen and messing with your browser settings is to completely eliminate it from your system.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

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:

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


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.

If you want to avoid the risk, we recommend downloading SpyHunter
