GuideLibrary is a type of adware that is specifically designed to target Mac operating systems. It is often bundled with other software or disguised as a useful application, and once installed, it begins to generate intrusive advertisements and pop-ups. This adware can also redirect users to potentially harmful websites, collect personal data, and negatively impact the performance and speed of the affected device. GuideLibrary typically infiltrates a Mac system through deceptive techniques such as “bundling” or “social engineering”. In bundling, the adware is packaged with other free software that the user downloads and installs. The user may not be aware that they are also installing the adware. Social engineering, on the other hand, involves tricking the user into downloading and installing the adware, often by masquerading as a legitimate or necessary program. Once the adware is installed, it can start causing various issues on the Mac.
