Aim Buddystats

First, i'm on a Mac Book pro.

I got a link sent to me from a friend on Ichat that took me here:
(Admin Note: Link removed)

It showed my user name (stevord) and my friend's name (pkrmama)

There is a button you click to 'compare'.

I stupidly clicked the button and then saw a thermometer of sorts for each person start to rise and then stop. Nothing else happend.

I immediately suspected i was scammed and my friend confirmed that she got the same thing.

I can't find any info on google about this. How can i find out if my computer has been compromised, either by key loggers or whatever?

I NEVER fall for this stuff so i'm kind of pissed that i wasn't more careful.

Your help will be appreciated.
