Scan your computer. Restart it, restore it. I wouldnt log in your accounts yet.
Lol'd at restore your computer, that won't do shit.
Also to the other guy - it's not patched they can always make javascripts that download files on your other computer. If you run their javascript, you don't know what's it does yet - but it's obviously malicious.
At OP:
If you ran the javascript = you're infected
If you closed your browser or declined the java script = you're clean
