Recognising Fake Antivirus Pop-Ups
Launch library · evergreen read

A pop-up claiming your device has hundreds of viruses, urging you to download software or call a number immediately, is almost always fake, designed to alarm rather than genuinely inform, regardless of how official it happens to appear. The dramatic number itself is usually the clearest giveaway of all.
Genuine antivirus software installed on your device does not typically alert you through a browser pop-up, and legitimate security warnings tend to be considerably calmer and more specific than the dramatic, urgent language these fakes generally rely on. A calm, factual tone is a far more reliable sign than urgency.
Closing the browser tab or window, or restarting the device if it will not respond, rather than clicking anything within the pop-up itself, avoids inadvertently downloading the very malware the pop-up is genuinely trying to distribute. A forced restart is rarely the wrong move if a screen seems stuck.
Keeping one reputable, well known security software installed and updated, rather than reacting to alarming pop-ups, remains the considerably more reliable way to actually protect a device over the long term. One trusted program is worth far more than reacting nervously to every single alert.
