Fake tech support warning: stay safe while fixing your own tech

How fake tech support works

1. 1

   A scary message appears,

   Often full screen, saying your computer is infected or locked, sometimes with a loud alarm.

2. 2

   It gives a number to call,

   Claiming to be Microsoft, Apple, your internet provider or another well-known name.

3. 3

   The "technician" asks to connect to your computer,

   Then shows you fake problems.

4. 4

   They ask for payment,

   Or for your bank details, to "fix" it.

Red flags

• A pop-up you can't close

  That says to call a number.

• A warning with a countdown,

  An alarm or flashing text.

• An unexpected call

  Saying your computer is sending out errors.

• Requests to install remote access software,

  Or to log in to online banking while they watch.

   And don't click inside the pop-up.

   Without reopening the last tabs.

1. 1

   Disconnect from the internet
