Maybe a demo version of antivirus software would work also, just want to make sure my mac is clean at this point in time given my recent pc troubles. I also sometimes download pc files onto my mac and then transfer them onto my pc, and once about a week ago i accidentally clicked on a virus email on my mac (I think it was the mydoom virus though so I am pretty sure I was immune to the virus since I was on a mac.

You are right, there are no viruses on the Mac. There is no need to worry about PC viruses opened on your Mac (in e-mails, for example) because they will physically
not work on your Mac. I am positive your machine does not have a virus.
Trojans, however, are a different matter altogether. It would be hard to explain why you're relatively safe against trojans, but here's the short version: Make sure you know what you're downloading and what it does. If a program you download asks for your password in order to perform administrative tasks, make sure it's something that really needs an administrator for (installing system files usually).
It is generally a good rule is to stick to sites like
versiontracker.com or [url=http://www.macupdate.com/[/url] for downloading shareware applications, and search a forum like MacNN before you install or run something that seems fishy.
