ListSchedule is a type of potentially unwanted program (PUP) that infects macOS devices. It typically enters a system through software bundling, where it is included as an optional installation alongside legitimate programs. Once installed, ListSchedule may display intrusive pop-up ads, redirect users to suspicious websites, and track their online activities for targeted advertising purposes.
ListSchedule can also modify browser settings, such as the default search engine and homepage, without the user’s consent. This can lead to a degraded browsing experience and increased exposure to potentially harmful content. To prevent ListSchedule infections, users should be cautious when downloading software from unknown sources and always opt for custom installation settings to deselect any additional programs that may be bundled with the desired software. Additionally, regularly updating antivirus software and performing regular system scans can help detect and remove ListSchedule and other PUPs from a Mac device.
