TROIAN.ADH.2 / Blocked?

Hi, i have a big big big doubt. When i downloaded a stupid file that i wanted, Norton notified me that he 'BLOCKED THE TROIAN'. But again he notified me that someone or something tryed to attack my pc. 

This is the screenshot. In the first, Norton said in 'Action' that he had solved the problem, i don't know what's happend but it just blocked it.

In the second, Norton said just he blocked the attack, 'mariagiovanna' is my computer, and the computer in attack is mine. So, in the Action, Norton don't say nothing. 

 

So, Norton had block the virus? Can i stay calm? Please help me.
