OS X virus: did I dodge a bullet?

Factual Questions
1

A couple of nights ago, I was looking at a site (ok, it was porn) and it had a link to download Flash 10. I downloaded and launched the installer and was told that the program to be installed was MacCinema. I stepped through the wizard and decided to back out of the process before installing. The next night I went back to the site and decided to go directly to adobe and download the latest Flash player. I went back to the site and noticed that it still wanted me to install Flash 10, so I googled MacCinema and discovered that it was indeed a trojan horse. I however am unsure if the virus is contained in the software to be installed (which I am pretty sure of) or in the installer itself (I hope not). Does anyone know?

Thanks,
Rob

Here’s how to determine if you have it:

BTW, it’s a Trojan, not a virus.

Just to underline something that may not be clear from beowulff’s link. MacCinema is indeed a later version of MacAccess.

Here’s the MacCinema link from the same threats site:
