Chromium Removal Guide

What is Chromium

Chromium is browser similar to Google Chrome. It is built on an open-source platform called Chromium. Many adware developers use it to develop Chrome-like browsers and install them using “bundle” along with free programs. Chromium sets itself as a default browser for internet surfing and replaces Google Chrome icons on the desktop and pinned icons on the taskbar. Users sometimes do not recognize the change. Chromium can show ads, pop-ups, and banners, modify search results and earn on users clicks on these advertisements. It is usually has default pre-installed Cassiopessa.com (Cassiopesa.com) search or Any Search Manager extensions. This is used to promote various goods and software of low-quality. Here are a complete guide and step-by-step instructions to help you remove the Chromium browser from Windows or Mac.

Adware developers use it to install potentially unwanted apps secretly. To protect from such apps you need to be careful during installation or use antimalware with PUP (potentially unwanted programs) protection. Among the best is SpyHunter – it will help you to remove the Chromium browser.
