Malicious website, now computer acting weird - help please

I was looking for "see through" fireplaces and searched on google. This led me to a website which is (DO NOT CONNECT please): "picadezign.com/indzh/show.php?pg=236368 *368" which supposedly showed photos of these fireplaces. This was a connection to a malicious website that started scanning my computer for viruses without my permission. I first tried to shut down safari, then turn the computer off using the power button but no surprise no luck. So I unplugged the computer and closed the lid and removed the battery. Turned it on again and it went straight to the website again (no login screen). So I unplugged the computer, closed the lid, removed the battery and unplugged the WiFi. Waited and then turned on everything again. This time, computer turned on but safari and mail would not connect to the internet. Turned everything off again, then on again and things seemed fine, the internet connected etc.
Then I went out of the room and the computer went to sleep with the lid open. But it would no longer wake up from sleep regardless of what I did. So I turned it on and off using the power button and it seemed to work.
I repaired permissions though this is not the problem. Any other housekeeping/fixing ideas? Also, who can I report the bad website to (there was no warning on either Yahoo search or Google search that it was malicious).
