GTSCAN virus? Need to know if my computer has been compromised

[rockchick1959]

Hey, this is my first post so I hope I'm putting it into the correct forum. My apologies if I'm wrong.

I have a MacBook. Today while I was on Myspace, a pop-up window and a new tab opened informing me that GTSCAN was performing a scan of my computer. This is weird because I was on my own page (shouldn't have been a phishing site) and I have my block pop-up windows option enabled. Was this a virus? How do I know if my computer was compromised in any way (such as my information or identity stuff stolen)? I don't have security stuff on my laptop because I was always told Macs don't need it and that it would actually slow up and gunk up my computer. Help?

You're fine. There's no viruses in the wild that can infect Macs, and you would had to download something to be infected with a trojan, and install it. What you got was just a spam pop-up hoping you would click on it and buy their fake anti-virus software that likely doesn't even run on Mac. Here's some more details on GTScan.
