    Overview

    Tech support scams trick victims into believing their computer is infected with viruses or has serious security problems, then charge hundreds or thousands of dollars for unnecessary 'repairs.' These scams target seniors disproportionately and use fake pop-up warnings, unsolicited phone calls, and search engine ads to reach victims. Once scammers gain remote access to a victim's computer, they can steal personal files, install actual malware, and access financial accounts.

    How This Scam Works

    1

    Fake pop-up warnings appear in your browser claiming your computer is infected, displaying a phone number to call for immediate help.

    2

    Unsolicited phone calls from people claiming to be Microsoft, Apple, or your internet provider, warning about detected security threats on your device.

    3

    Scammers convince victims to download remote access software like TeamViewer or AnyDesk, giving the scammer full control of the computer.

    4

    Once connected, scammers show fake 'evidence' of viruses by displaying normal system logs or running fake diagnostic tools.

    5

    Victims are charged $200 to $1,000+ for unnecessary services, often through gift cards, wire transfers, or by accessing bank accounts through the remote connection.

    Warning Signs

    Unexpected pop-ups warning about viruses with a phone number to call
    Unsolicited calls from 'Microsoft' or 'Apple' about your computer
    Requests to install remote access software like TeamViewer or AnyDesk
    Pressure to pay immediately with gift cards or wire transfers
    Claims that your computer is sending spam or has been hacked
    Warnings that your computer will be disabled if you do not act now
    Requests to access your bank account through the remote session

    How to Protect Yourself

    1Microsoft and Apple will never call you unsolicited

    Major tech companies do not make outbound calls to customers about security issues. Any such call is a scam. Hang up immediately.

    2Close suspicious pop-ups safely

    If you see a virus warning pop-up, do not call the number. Close the browser using Task Manager (Ctrl+Alt+Delete on Windows, Command+Q on Mac). These pop-ups are fake.

    3Never give remote access to unsolicited callers

    Do not download TeamViewer, AnyDesk, or similar software at the request of someone who contacted you. Only grant remote access to technicians you contacted through verified channels.

    4Use legitimate security software

    Install reputable antivirus software from known companies. Your computer likely already has built-in protection (Windows Defender, macOS security).

    5Talk to a trusted person before paying

    If you are concerned about your computer, talk to a family member, friend, or visit a local computer repair shop. Never make payments under pressure from an unsolicited call.
