Some BTC was sent back to you as change. Are you sure someone didn't sneak onto your laptop and make a purchase? 
Nobody was at (my) home that could have done that. At that time being i wasn't at home, so that even scares me more.
So, apparently i got hacked (or backdoored) and now i've lost 0.5602 bitcoins from my wallet since 21:32 GMT +1, the 31st of March.
I have NO idea how this could have happend as that i have full AV,
The recipient's address is "1FmMasfuEE6wtpzdWiVnDynfJ5tyyVbhP3".
Can anyone give me some advice / help here?

can you be more precise?
what is your bitcoin client, which one is your address
Bitcoin-QT; 1AV1CdiYq2uSUwJzdu5UmLAD8GdQxRwBhE
Just ran a check with Hitman PRO; it flagged all my cgminer exe's as malware, but i've been using them for about half a year and nothing like this has ever happened in the past.
so your computer was under someones control via Internet.
Hard to say what happend... how many altcoins wallets have you got? Are you using antivirus, which one, are you behind a firewall and is your router behind another firewall?
What is your Internet connection?
It seems so, Yes.
7 or 8? But mainly 3-4 that i use next to the bitcoin wallet(Spain, Vert, HVC and Roto).
Yes, Avira, it's up to date.
Yes, firewall is active on router, not on computer.
Wired internet connection, COAX.
there are many possibilities ..
And why firewall not active on computer?
Windows user?
