Although Mac OS has outstanding security features, it is susceptible to potentially unwanted programs (PUP) that are often installed without user’s consent. Such programs pretend to be legitimate, but in reality, they do more harm than good. They often employ a large amount of system resources and may even intentionally slow down your computer. They can spam your browsers with annoying advertising and pop-ups, urging you to buy the program’s full version, take over your search engine, and can collect your personal data, posing a serious security risk.

A potentially unwanted program can enter your computer bundled with freeware that you plan to download. They are typically advertised in one of the installation steps as free extra or an optional offer, and you can install it unintentionally if you skip some installation steps.

Besides, they are often advertised as Mac optimization tools or toolbars for browsers, and you can intentionally download them with a hope to make your computer run faster or add great features to your browser. Instead, they will cause a lot of problems and bring you a lot of stress and uncertainty. You can also download PUPs as fake anti-adware or antivirus apps, Mac cleaner apps, or keyloggers that are often used to monitor online activities of children or employees.

You can easily identify that you have the PUP virus on your computer if you notice the following signs:
