Even the macOS is vulnerable to browser hijackers, adware, and other malware these days. If you consider intrusive pop-ups or strange extensions showing up in your Safari browser, you're almost certainly dealing with the Safari virus.

Yes, the Safari browser can be affected by malware, adware, and malicious extensions, though it is not a "virus" in the traditional sense of a self-replicating file. Most Safari-related security issues manifest as "browser hijackers" that change your homepage, inject unwanted advertisements into websites, or redirect your search results to suspicious pages. Because Safari is deeply integrated into macOS and iOS, it utilizes "sandboxing" to prevent malicious code from accessing your entire system. However, users can still be tricked into installing malicious plugins or extensions that compromise their privacy or steal data. In 2026, phishing remains the biggest threat to Safari users, where fake websites mimic real ones to steal passwords. Apple frequently releases security patches to close vulnerabilities (zero-day exploits) that could allow hackers to run code through the browser. To stay safe, you should always keep your software updated, avoid clicking on "You have a virus" pop-ups, and only install extensions from the official App Store or trusted developers.
