What is the Critical Virus Alert Scam?

The “Critical Virus Alert” is a phishing scam that falsely claims victims’ computers are infected in order to trick them into clicking on a specific link that leads to a deceptive website. Upon entering this site, a fake scan will run, displaying a bogus report indicating the presence of multiple viruses on your Mac. In such a scenario, you will likely be presented with an option to purchase a fraudulent subscription or service, inadvertently downloading and installing malware.

Where do Critical Virus Alert pop-ups come from?

Much like “Ask You” and fake McAfee virus pop-ups, Critical Virus Alert scams are generated through malicious push notifications, deceptive websites, misleading advertisements, potentially unwanted applications, and adware that may be installed on your Mac. Typically, clicking on unfamiliar links, opening attachments from spam emails, visiting suspicious websites, and downloading free bundled apps can increase the likelihood of adware infection, leading to various pop-up scams.
