Update-mac.com is a fraudulent website designed to deceive Mac users into believing that their computers are infected with viruses or malware and need immediate updates or security fixes. It employs scare tactics such as displaying fake virus alerts and security warnings to trick users into downloading potentially harmful software. This website is typically encountered through redirects caused by potentially unwanted applications (PUAs) that are unknowingly installed on the system.
Update-mac.com exploits browser notifications by tricking users into enabling them. When a user visits the website, it presents a pop-up that asks for permission to show notifications. If the user agrees, the site starts to flood them with unwanted ads, dangerous links, and other malicious content. It can affect various browsers including Google Chrome, Mozilla Firefox, and Safari, implying that both macOS and iOS devices can fall victim to this scam. The best way to prevent such infections is by being vigilant about the applications you install, the websites you visit, and the notifications you approve.
