How This Scam Works
Critical Risk — Remote Access Fraud
Microsoft does not send unsolicited emails about virus infections or computer security issues. Never call a number from these emails or grant remote access to your computer.
You receive an email claiming your computer has been compromised, infected with a virus, or is at risk. The email says it's from Microsoft Support and provides a phone number to call for immediate assistance. In some versions, the email includes a fake Windows Defender or Microsoft Security alert.
When you call the number, the person posing as a Microsoft technician convinces you to install remote access software (like AnyDesk, TeamViewer, or UltraViewer). Once they have access to your computer, they may show you fake "virus infections" in system logs, install malware, access your banking websites, or steal personal files. They then charge you for unnecessary "repairs" or trick you into sending money through wire transfers or gift cards.
The FBI's IC3 reported that tech support fraud caused over $924 million in losses in 2023, with victims over 60 accounting for the largest share (over $590 million). Microsoft's Global Tech Support Scam Research has found that a majority of consumers across surveyed countries have encountered tech support scams, making it one of the most pervasive fraud types worldwide.
Red Flags
- Email claims your computer is compromised or infected
- Provides a phone number to call for 'Microsoft Support'
- Sender address is not from @microsoft.com
- Contains fake Windows Defender or security scanner results
- Uses fear language — 'Your computer will be disabled' or 'Your data is at risk'
Microsoft never sends unsolicited emails about computer problems. Microsoft support only contacts you if you've initiated a support request through their official channels.
What You Should Do
What To Do
- Do not call the phone number in the email
- Do not install any remote access software if asked
- If you already gave remote access, disconnect from the internet immediately
- Run Windows Defender from your computer directly (it's built into Windows)
- Change your passwords for banking and email if remote access was granted
How to Verify Legitimately
If you're concerned about your computer's security, open Windows Security (built into Windows 10 and 11) by clicking Start and typing "Windows Security." Run a scan from there. If you need Microsoft support, go to support.microsoft.com and initiate contact yourself. Microsoft's real support will never ask you to pay with gift cards or wire transfers.
