My steam, account was hacked :O

I was playing cod and I kept getting disconnected with the message "your steam account is currently logged onto another computer, please log of your other computer then log back on to this one".
Well something along those lines.

Then 2 days later it said your steam account has been disabled.

So I knew it had been hijacked/hacked.

I went to steam support ad showed them prove that the account was mine and my account has been enabled today!
