First, Determine the Source: System or Website?

Warnings like "Your device has been infected with a virus", "Please repair immediately", or "Data is being leaked" may not come from the system or security software. Often, they are just false alerts pushed continuously by a website that has obtained browser notification permissions.

Fake Notifications Often Use Fear and Urgency to Prompt Clicks

Common phrases in fake security notifications include device viruses, account freezes, multiple dangerous items detected, requiring immediate cleaning, or installation of security tools. Their purpose is usually not to help you resolve issues but to trick you into clicking links, downloading software, entering data, or engaging with fake customer service processes.

To Identify Real vs Fake, Check These Four Things

First, check if the notification comes from an unfamiliar website. Second, see if it pressures you to click immediately. Third, check if it requests you to download unknown tools. Fourth, see if it requires your account, password, payment information, or remote assistance. If the source is unclear and it asks you to act, do not comply.

Flowchart for determining real vs fake browser security notifications, including checks for the source, urgency to click, downloading requests, and data requests.

When Handling Fake Notifications, Do Not Act From the Popup

First, close the notification without clicking any buttons. Go to the browser settings under website settings or notification permissions, and remove notifications from unfamiliar, suspicious, or unused websites. If necessary, clear cookies, cache, and data from suspicious websites, then use trusted security tools to check your device.

Mobile Browsers Face the Same Issues

Website notifications on mobile can appear like system push notifications, making it particularly easy to mislead users. Check the notification or site permission settings in your browser app to block sites that keep sending strange notifications and clear that website's data.

Real security alerts will guide you back to trustworthy settings or official tools for verification; fake security notifications will urge you to click, download, or pay immediately. When faced with a security warning from an unfamiliar website, close it first, then check the source in your system or browser settings.
