Caller: Alex

Spoke to 2 people both were Alex.
Said they are contractors to Microsoft and they found suspicious download on my computer. They even had my mictosoft software serial number.
In between the coversation asked me my age,I asked for his number to call back and disconnected.

Never pick up any call from these number, If they don't leave proper Msg I don't bother to call them back either.They can go to hell

Got a call telling me my Windows app has and could be hacked. I then hung up on him (Richard)

Had a missed call from it, called back and got a message from Optus saying the mobile number had been disconnected. Have put on my don't answer list.

Scam number

I called back number (07) 3040 7774 rang once then goes to busy tone.

trying to get your information without telling me what he was selling.
