Arphanpyer is an advertising app that installs in popular browsers such as Firefox, Chrome, and Edge and changes their settings without the user’s approval. Arphanpyer will generate various types of ads, trigger automatic page redirects, and replace the default search engine.

Arphanpyer will display pop up ads and messages

The changes that this app makes are intended to facilitate its advertising agenda which is why the new search engine will likely show more advertised sites in its results and why your browser will frequently open new tabs with the sites it is designed to popularize.

Another change that Arphanpyer will likely introduce to the browser is the replacement of the homepage/ the new-tab page. The new homepage address is likely going to be the address of another site that Arphanpyer seeks to promote or maybe even the official site of this app. All of these changes will be enforced upon your browser and you won’t be able to reverse them for as long as Arphanpyer stays installed on the computer. This frustrates a lot of users and even makes some of them think that they are dealing with a virus program, a Trojan, or Ransomware.

Arphanpyer is not a threatening piece of malware that will damage your system or tamper with your data – it is an app intended to promote different kinds of content from within your browser and make money via those ads. You may have heard about Pay-Per-Click and Pay-Per-View – those are remuneration models that allow advertisers to make money based on how many clicks and visits their ads and advertised sites gain. Apps like Arphanpyer,, are based on these remuneration models and they dictate the behavior of the application. However, since the activities of these apps oftentimes tend to become quite aggressive and intrusive, the term used to refer to them is browser hijackers. Though the term “browser hijacker” may sound a bit unnerving to some users, know that most applications that can be categorized as hijackers aren’t really harmful and they aren’t programmed to damage the PCs that they are installed on. Nevertheless, you still shouldn’t keep a hijacker on your computer because of the indirect dangers that may be related to it.

Indirect hazards related to browser hijackers

One of the main security concerns users have about these apps is the questionable nature of their adverts and page redirects. It is uncertain if a given hijacker-generated ad would land you on a legitimate and helpful site or on some web location that contains unsafe elements such as pirated downloads, viruses, Trojan, or Ransomware. Even though the hijacker itself won’t attack your computer, the fact that its ads could be coming from anywhere and you won’t know if a given ad is safe until you click on it (or even after that) means you should refrain from interacting with anything that Arphanpyer may put on your screen. Better yet, uninstalling the unwanted app will save you the trouble of navigating through those and will allow you to return your main browser to its regular settings.
