How to remove Microcosm (Virus Removal Guide)

Microcosm (also called Microcosm – New Tab Extension) is a browser extension that changes your existing internet browser settings. The Microcosm extension will replace your homepage, new tab page, and default search engine with search.microcosmtab.com or another website. This causes your internet browser to start on a new website when you open a new window or tab and redirect to a new website when you search the web.

Microcosm

One of the biggest concerns with the Microcosm extension is that it is often advertised on websites that display malicious advertisements and host malware. If you found the Microcosm extension attached to your browser or have visited a website that displays Microcosm advertisements, it is likely that your computer has become infected with other threats (such as MyStart Space and Search grab) that should be removed.
