Scam recognition

How tech-support phone scams work, and what to do

A surprise call saying your computer, account, or security software has a problem is a reason to stop, not to follow the caller’s instructions. End the call and find support through a company contact you already trust.

How do tech-support phone scams work?

Scammers may pretend to represent a known technology company, describe a virus or charge, or direct someone to install software that lets them control a device. The FTC explains that unsolicited callers may seek financial information, remote access, or payment after showing a fake problem. See the FTC’s tech-support scam guide.

What should I do during an unexpected support call?

  • Do not click a link, install an app, read a one-time code, or share a password, bank detail, or security code.
  • Do not call a phone number displayed in a pop-up, text, renewal notice, search advertisement, or the unexpected call itself.
  • End the contact. If you are concerned, open the company’s official app or use the support number from a bill, product documentation, or verified website.
  • Ask a trusted person for a second look before paying or granting access.

What if I already gave remote access?

Disconnect the device from the internet if practical, update security software, run a scan, and change passwords beginning with the email account that can reset other accounts. Contact the financial institution if payment or account information was shared. The FTC’s what-to-do guidance explains how to contact the service used to pay and report fraud.

Can call labels solve this?

No. A label can be useful context, but it cannot promise perfect protection and an unlabeled call is not automatically safe. For a cautious setup that still preserves wanted calls, see the call-screening options guide. For account and device follow-up, use the Privacy Guide for U.S. households.
