Sorry but macs DO need security software!!!
Not having any is infact irresponsible.
At the risk of causing offence- the fact that you think that you don't need security software indicates that you really should be running some.
Even linux users should run scanning software from time to time.
Trojans exist on all platforms.
Not even Apple claim that their software is free from the risk of malware.
Sorry to be so blunt but the more that users deny the need for security the faster malware propagates throughout the internet.
