How Did I Get StyleLab Installed on My Mac?
StyleLab Adware can get installed on your Mac in a variety of ways. Such programs are typically bundled with freeware or shareware applications, hidden in the installation process. It can also be installed via malicious webpages or links that redirect you to a malicious site. Additionally, it can spread through emails, attachments, and other online sources.
Most of these distribution mechanisms aim to trick you into installing the program without considering the side effects. For the purpose of achieving this goal, bundled software installers are used as well as fake software updates delivered over compromised web pages.
