LinkInfo is an intrusive application that combines the functionality of both adware and browser hijackers. It targets mostly Mac users and aims to sneak itself onto their computers unnoticed. It relies on the typical distribution tactics associated with such PUPs (Potentially Unwanted Programs) - bundling and fake software installers/updates. To avoid letting such unwanted applications in, users should always check all of the settings when installing applications from unfamiliar sources. The additional applications are often hiding under the 'Advanced' or 'Custom' menus.
The adware part of LinkInfo is responsible for generating monetary gains by running an intrusive ad campaign on the Mac. It will start delivering various questionable pop-ups, banners, surveys, etc., and could impact the browsing experience on the device drastically. Furthermore, the advertisements themselves should not be trusted. They may employ deceptive or clickbait tactics to entice users into engaging with them. Afterward, the advertisements could lead to shady or outright unsafe third-party websites.
Another consequence of having LinkInfo installed on your Mac is that it will establish control over the user's Web browsers. More specifically, it will force the homepage, new tab page, and the default search engine to now open a promoted Web address. In nearly all cases, these browser hijacker applications are tasked with generating artificial traffic towards a fake search engine. Users should keep in mind that fake engines do not deliver results on their own. They will either redirect the search query through a legitimate engine or start a redirect chain that could go through several dubious ones before delivering low-quality and ad-filled results.
In addition, nearly all PUPs also are equipped with data-collection routines. Users risk having their browsing activities monitored, packaged, and then uploaded to a remote server. The operators of the specific PUP can then decide how to exploit the received data and could even offer it for sale to interested third parties. To avoid such outcomes, it is strongly recommended to remove all PUPs from your Mac as soon as possible.
