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.


How to remove Critical Virus Alert pop-ups?

To manually remove Critical Virus Alert pop-ups from your device, you need to follow the steps below. If you want to get rid of these pop-ups and other potential threats quickly and permanently, it is recommended that you download Antivirus One and perform a comprehensive scan of your Mac.


Step 1: Clear and reset your browser

Critical Virus Alert pop-ups often come from malicious websites that you may have accidentally visited. To be on the safe side, clear your browsing history and reset your browser.

Note: The instructions below are for Chrome, but other browsers will be similar.
