Hey guys! So I was just browsing the web on my new macbook pro and i got hit with the fake FBI MoneyPak Virus. I had heard about this virus before so I just restarted my computer, then reopened safari and deleted my cache and cookies. Is that all I need to do or do I need to download a security program? I wasn't dual booting into windows or anything and my computer is on the latest version of mountain lion. Please Help!!!!!!!!
