Do not install from the alert
Use the operating system's or trusted security product's own interface if you want to check device status.
Do not call numbers in alarming browser pop-ups
A legitimate system warning does not need an unknown web page to route you to a random support number.
Close the page or browser normally
If the browser behaves unexpectedly, use supported browser troubleshooting rather than following the pop-up's instructions.
Seek trusted help if persistent
Repeated redirects or unwanted software may need a reputable technician or official security guidance.
