MultiSet Adware – Why Is This App Installed on My Mac?
A common reason for the sudden appearance of MultiSet adware on Mac is a click on a fake update. The most popular update of this type is for Adobe Flash Player. Pop-ups may show up on your screen to inform you that your Flash Player is out of date. Don’t let them make you install the offered update because instead of downloading any update, you will get a potentially undesired program on the machine.
The activation of MultiSet adware on your Mac may enable this unwanted application to replace the default search engine and new tab page in all installed web browsers. Changes can occur without your consent. Additional browsers’ settings could be altered to display various advertisements.
Adware programs operate with the sole purpose to monetize their access to macOS. But this often suggests that they display shady ads that link to unreliable sources.

Sites promoted by adware and ad-supported apps like MultiSet may host online scams, rogue applications, and even malware.
