My laptop didn't have bluetooth, so I bought one of those bluetooth USB sticks (disk says it's a USB Bluetooth 4.0 Dongle). I am going to use it mainly for my wireless headphone.

I have a series of questions about that:

 

#1 - I heard in the past that if you keep your bluetooth on, hackers can easily hack your device. Is that true?

 

#2 - During the install process it says "please select the default settings for Harmony". I have the option to turn the discovery mode off & disable/enable SCMS-T. How should I install it for the best security?

 

#3 - Should I put the bluetooth folder in the exclusion list or put it in the trusted application list in Malwarebytes 3 or Kaspersky Total Security?

 

#4 - Do you recommend to turn bluetooth off when I don't need it to increase security?

#1 - Not really.  Since the range of bluetooth is typically less than or equal to 10m/33ft (though, in absolutely ideal conditions, could be as far as 100m/333ft) someone has to be very near to you, and your laptop needs to be discoverable at the time.  I don't consider having to be at close range like that "easily" able to gain access via bluetooth.  

 

#2 - I keep discovery mode off except when I need to pair devices.  With regard to SCMS (Serial Copy Management System, see BC thread here) it probably depends on whether you'll be using the device in some way with music protected with same.

 

#3 - you should not need to do either

 

#4 - Sure.  It can also save a bit of battery life (though very little) and why have any communications channel open if you are not using it at the time?
