What the scammer wants
To frighten you into calling, then gain remote access to your device to 'fix' a non-existent virus, steal data, and access your banking.
Red flags in the message
- Full-screen 'infected' popup with a support number
- Instruction not to restart and to call now
- Request to install remote-access software
- Asked to log into your bank while connected
A safe response
Don't call. Close or force-quit the browser (you can safely restart). A web page can't scan your device, and real tech firms don't cold-prompt you to call and grant remote access.
What not to send
- Remote access to your device
- Payment
- Banking details
What to do if you already replied
- If you gave remote access, disconnect from the internet and uninstall the tool
- Change passwords from a clean device and contact your bank
- Run a security scan; see the remote-access cleanup guide
Evidence to preserve
- Screenshot the full message or call details
- Note the sender number, email, or profile
- Save any links (without clicking) and payment details
- Record dates and times
