Change Parameter

Change Parameter is a PUA (potentially unwanted application) that redirects the user’s browser, causing it to open various promoted sites. Change Parameter is intended to operate as a site-promoting tool that modifies the user’s browser, replacing the search engine and the homepage without permission.

The Change Parameter App on Mac

If you have encountered such a software component in your Chrome, Firefox or other popular browser, then you are most likely willing to find a way to remove it to stop it from further tampering with the settings of your browser and putting ads and page redirects on your screen. We can help you with that but we must first tell you a bit more about the characteristics of this unwanted app so that you know what you have on your hands.

Change Parameter for Mac

Change Parameter for Mac is a browser-hijacking app that adds a new search engine to the main browser of Mac computers. The goal of Change Parameter for Mac is to redirect the user’s searches to certain sites that need promotion and thus earn Pay-Per-View revenue.

In other words, this is an advertising app and not an actual malware virus like a file-encrypting ransomware virus or a Trojan horse. In most cases, the worst thing a browser hijacker is going to do is to obstruct your browsing process and make you feel very irritated and frustrated because you wouldn’t be able to easily use your browser without clicking on some popup or banner.

However, experts agree that it could, in some cases, be potentially unsafe to the system to keep a browser hijacker attached to the browser. The problem is that most such apps do not filter the ads and redirects they display which could, in turn, potentially lead to exposure to unsafe and possibly even harmful content.

What is Change Parameter?

Change Parameter is a software component similar to a browser extension that gets integrated with the browser and starts to display ads. Change Parameter is also known for rerouting the user’s searches to unknown pages, some of which may contain potentially unsafe elements.

The best response if you notice a browser hijacker in your browser is to remain calm and to look for a way to uninstall the page-redirecting software. Usually, removing a hijacker is not as simple as uninstalling a regular app because most hijackers are intentionally created to have a difficult removal process. After all, the longer the unwanted app stays attached to your browser, the higher the potential end-profit that could be earned from it becomes. This is why the creators of such software are interested in discouraging users from trying to remove the hijacker by making the removal process as difficult as possible.

The ChangeParameter app

The ChangeParameter app is an example of a browser-hijacking software component that can secretly take over important functions of your browser without your agreement. Most users notice the ChangeParameter app after it replaces the browser’s search engine and begins filling the search results with ads.

If you don’t know how you can remove this app from your Mac but are concerned that its presence there may eventually lead to attacks from more serious forms of viruses (such as ransomware, Trojans, and the like), we encourage you to try the removal instructions available below and/or the recommended professional anti-malware tool that has been tested against unwanted apps like this one.
