...my password was changed by the way which is i guess a clear sign my account was compromised... somehow? I do keep to date nod32 and spybot, firefox. My lappy was off at the time, 2 factor login auth into coinjar? No
Yes I think the Support Staff needs to check your login and check cross check the IP and time and trace it for you.
All online wallets - you should have 2 factor authentication active (so you need a new code from your mobile phone to send btc).
I think coinjar has 2 factor authentication and sms - so you can activate both if you so wish. So that means if you want to transfer btc, you need to have your lock enabled (10 points each means 20 points to send funds out).
They can track the BTC movement to see if it was internal or if it was a withdrawal.
Just hope its a coinjar internal transfer - and they can credit you back.
Change of password is a bad sign too - they should be able to trace their logs to see when it was changed, at what IP and time.
The problem with Windwos computer, it can be affected without you realising it...thats the problem.
Also, anybody else have access to your laptop? Does it need pw to access it?
