Windows Security Alert - Your PC is at risk

Scammers deliberately mimic the appearance of legitimate system messages to create convincing fake errors. Fake Windows Security Alert Popup may be a real system notification or a fraudulent one — knowing the difference prevents both ignoring real issues and falling for scams. Legitimate system errors: appear in expected locations (event log, OS notification center, application's own window), use consistent branding and terminology, do not ask for payments or remote access, and can be verified through official support channels. Scam errors: appear in browser windows or pop-ups you did not initiate, claim your device is "infected" or "locked", display a phone number prominently, create urgency with countdown timers, and use aggressive audio alerts. A real Microsoft or Apple error never includes a phone number and never asks you to call immediately. Verify suspicious messages by: closing the browser or notification, searching the exact message text online, and contacting the company through their official website (not any number displayed in the error). If remote access software (AnyDesk, TeamViewer) is mentioned as part of the fix, it is a scam.
