What is Mcls.xyz?

Mcls.xyz is the webpage that can start appearing in your browser instead of your default search engine. This behavior indicates that your Mac is infected with browser hijacker. Browser hijacker is a sort of potentially unwanted program which is primarily used to boost up affiliate websites’ traffic. To do so, it provides users with misleading search results leading to ad sites. This is not so much dangerous as an irritating feature. The worst part of this is that browser hijacker can install other unwanted apps without the user’s permission. This makes your device more affected as well as reduces its performance. The only way to stop this activity is to remove Mcls.xyz right now. Follow this guide to completely uninstall browser hijacker.
