TypicalUnit is yet another dubious PUP (Potentially Unwanted Program) aimed at Mac users. It relies on questionable distribution techniques, such as bundling or fake installers to sneak itself unnoticed onto users' devices. Afterward, it will begin to monetize its presence by delivering unwanted and annoying advertisements while also forcing the installed Web browser to open a promoted address. In short, TypicalUnit combines the capabilities of adware and a browser hijacker.

Users should approach any advertisements generated by such unfamiliar sources with caution. The advertisements could employ deceptive or clickbait messages to entice users into clicking on them. Those that engage with the advertisements risk being redirected to shady third-party websites. Users could land on pages running phishing schemes, other online tactics, spreading more PUPs, or even serious malware threats.

At the same time, TypicalUnit will modify the Web browser's homepage, new tab page, and default search engine settings. All three will now be set to open a page promoted by the PUP, usually a fake search engine. Fake engines cannot produce any results. Instead, they take the user's search query and redirect it to a legitimate engine (Yahoo, Bing, Chrome). However, in some instances, the fake engine may initiate a redirect chain that passes through several dubious search engines. In the end, users will be presented with inaccurate and low-quality results that may be filled with sponsored advertisements.

The intrusive actions of the PUP may not stop there. Indeed, PUPs are notorious for spying on the user's browsing activities. Data such as the entire browsing history, every clicked link, and each search may be packaged and transmitted to a remote server.
