The fake helpdesk: "Your computer is infected"

A pop-up or phone call from "Microsoft" says your computer has a virus. They want to take a quick look.

Updated: 2026-10-17

1How they do it

  1. A loud alarm appears on your screen with a number to call, or you get a call.
  2. The "technician" has you install a program such as AnyDesk.
  3. He shows you fake viruses and asks for money for the "fix", or meanwhile logs in to your bank.
  4. Sometimes he makes your screen go black so you cannot see what he is doing.

2A real example

"Microsoft Security: your computer has been blocked. Call 0800 ... immediately. Do not close this window."
