Thank you for your help guys, I don't lose a lot, but it's so bad!!

Here is the transaction details:    https://www.blocktrail.com/BTC/tx/44e4335169afeba88d8d1ee1e94a4bf40f0d065e4b0d83dc37e9e23edf92e3f9

I made a restoration of my computer, and to be shure I will create a new wallet on my other computer, who is clean.

I will probably never get back my bitcoins, but I will be more vigilant in the future. 

I am only one to know my password.
One hour before the transaction, I was on the web to try to download the Utorrent soft, and a little clock app was installed on my pc.
I was thinking about a publicity software, but I open it, and deleted it at once after.
If I understand your awnser,  Navi, I think that this little clock app was probably a virus?
I’m so angry!!

Hi everybody,

I'm new here, I created my account because I have a question to Bitcoin's experimented users aha! 

I found tonight a weird transaction on my Electrum wallet, who send all the Bitcoins of my wallet. I never made this transaction! I don't know what is...

Maybe someone hack me? Is it possible? I'm so stressed!

I found the details of the transaction on Blocktrail.com, but I don't know how to read it, I d'ont have so more information of this transaction.

Please, if someone can help me, I can send you the transaction ID, or details, for your help?

Thank you very much!
