Most people refer to the hijacker as a virus infection. The truth, though, is that such software does not usually possess any dangerous qualities or have any malicious intentions. In fact, there are a number of significant differences between virus programs (Trojans, Ransomware, Spyware, etc.) and hijackers like the one we are currently talking about. For instance, a typical malware contamination could often have fatal consequences for the system and may result in permanent damage of the data on the HDD, theft of credentials, corruption and destruction of software as well as many other unpleasant effects. An application like, on the other hand, is typically very unlikely to cause any damage. Such ad-producing software would normally only affect your default browser. What might be irritating to some users is that the hijacker might start displaying ads on the screen during each browsing session, change the default homepage or search engine settings or trigger redirects to sponsored web pages without being authorized to do that. Still, these activities are not typically seen as harmful or illegal as they are part of commonly employed online advertising strategies such as Pay-Per-Click, Pay-Per-View or sponsored redirects and ads positioning. The good news is that, if you don’t want to tolerate the hijacker, you can easily uninstall the unwanted components and remove the nagging ads once and for all. We have dedicated a step-by-step Removal Guide on that so if you are interested feel free to use it.

How to prevent a potential hijacking of your browser in the future?

It might be very relieving for you to know that Browser hijackers could easily be avoided. Unlike computer viruses such as Ransomware or Trojans, which infect the web users through stealth and could hardly ever be detected on time without specialized security software, applications like cannot become part of the system this way. Most of the hijackers get distributed in software bundles and free download setups. They get installed on the computer as “additional” or “recommended” components to the main software package when the users opt for the Quick/Automatic setup settings. However, if the Advanced or Custom/Manual settings are selected, the user can easily disable the added components from the installation package and this way prevent them from becoming part of the system. Other useful tips for keeping hijackers away is to avoid downloading software from unknown and/or questionable freeware or shareware platforms in general. For additional safety, we usually advise our readers not to click on random ads, pop-ups, free download links or suspicious software update suggestions as well as to never install anything without carefully reading the Terms and Conditions as well as the EULA. It is also highly recommended to stay away from any streaming web pages and platforms that might be illegal because they may be used as tools for spreading applications like or similar ad-generating apps. If you want to limit the amount of website-hosted ads on your screen, it is a good idea to enable your pop-up blockers as well as your Firewall. They may manage to warn you about possibly dangerous web pages or sites that might try to install components on your computer that you don’t really want or need.
