Spam?

[Ratko Gavrilovic]

So I just went to my hotmail > sent items and I noticed over 1000 emails sent from me, to everyone in my contact list with stuff like:
Hey friend, take a look at: <Retarded link here>.
So obviously I did not send them myself, but how did something get access over my account for this?

Also some weird eToolkit appeared in my browser, taskbar and some survey shit.
I didn't install anything.

Seems you got a virus or malware. You might have clicked a malicious link.
If the messages are in your outbox, it means your account sent them.

So someone or something has been logging onto my account?
How can I clean this up?

It's almost impossible, I mean I had to make a new one. But yeah I cba'd to do proper research
