Do iMacs come with anti-virus?

Hello citrine:

iMac has a built in anti-virus or should I get one?

No, and no.

There are NO documented viruses that affect a Mac running OS X - none.

A/V software is , IMHO, a waste of money and resources on a Mac. Additionally, A/V software can cause problems with the system.

I'm having trouble on a website

What do you mean exactly? What is the url? What browser?

and wonder if my iMac has a built in anti-virus

No, and since that's not an issue on a Mac your problem is caused by something else.

I have OS X 10.5.7

Then you should post your question in a different place (this forum is for 10.6.) Go here:

Snow Leopard has some rudimentary malware protection built in. Namely, watching what downloads through the web onto your hard drive. Whether it's in a .dmg file, install package or what, it automatically searches these files for the handful of known Trojans out there. If it finds one, it let's you know that you should not run whatever it is you downloaded.
