Tech Support Scams: How to Spot Fake Microsoft & Apple Pop-ups

Most users can't easily tell whether a security alert is real. Scammers exploit that uncertainty by combining a dramatic warning with a friendly 'helper' to walk you through giving them control.

• Tech-support scam losses reported to the FBI IC3 reached over $924 million in 2023, with adults 60+ accounting for two-thirds of losses (FBI IC3 2023, IC3 Elder Fraud Report).
• Many tech-support scams now route victims through a refund-overpayment storyline that ends at a Bitcoin ATM or wire transfer (FTC, FBI).
• Pop-up scams that lock the browser and play an audio warning remain one of the most common entry points (Microsoft Digital Defense Report).

• Pop-up that fills the screen with a phone number and locks the browser.
• Caller from 'Microsoft,' 'Apple,' 'Norton,' or your ISP about a virus.
• Request to install AnyDesk, TeamViewer, UltraViewer, or LogMeIn.
• Refund storyline: 'we accidentally sent too much, please return the difference.'
• Pressure to keep the call going while you go to the bank or a crypto kiosk.

• Close pop-ups by force-quitting the browser (Cmd-Q / Alt-F4); never call the number shown.
• Never grant remote access to your computer to anyone you didn't proactively contact.
• Verify any 'refund' or 'charge' by logging into the account yourself in a new tab.
• Keep OS and browser updated; rely on built-in security (Windows Defender, macOS XProtect).

• Disconnect from the internet, then run a full scan with your built-in security tool.
• Change passwords from a different, clean device — start with email, then bank.
• Review bank and brokerage activity and dispute any unauthorized transfers.
• Report to FTC, IC3, and AARP if you're 60+.
