ChatZum is adware. It most often makes its way onto a Mac during the installation of another, legitimate program such as VLC or UnRarX. Although these applications in themselves are not malicious, and are not affiliated with the malware’s authors, the installer packages that bundle them together with the ChatZum adware are. Users are given the option to opt out of installing ChatZum by the installer program; however, ChatZum components are nevertheless installed on their computers even if they opt out.

Once installed on a target system, ChatZum will add its toolbar to the system’s web browsers, change the web browser homepage to a ChatZum page, and make ChatZum’s search engine the default.
