In both Leopard and Snow Leopard you will get a warning when you download an application from the Internet. The warning asks if you are sure you want to open it. This warning system allows you to make sure no malware sneaks past you unawares to self install on your Mac. The warning window contains a large yellow triangle with an exclamation point symbol in the middle.
Starting with Snow Leopard there is a second level of defense built in. This warning contains a red stop-sign shaped icon with an exclamation point symbol in the middle and warns you that if you install the downloaded software it will damage your computer. You are instructed to move the item to the trash. The malware is identified by definitions contained within the library core of your Mac and Apple updates that information as necessary.
