how to detect a a keylogger for mac

[EmmaL]

How do I know if spy software is installed on my computer?
Is there a way to find out if someone has installed this mac spy software onto my computer? I am not sure whether there are spyware programs that are going to detect my email or chat logs etc...... on my computer? I have heard that some spy software programs even claim that once it is installed, it is totally undetectable? Is it true?

Macs seem to have a lot less malware specifically written for them as they are in the minority as far as OSs go.

But my best defense is a decent firewall program that can block outgoing packets that may be sent to malware sites. Not sure what's available for Macs, but others here may have some ideas.

What makes you think you may have a keylogger installed?

Someone has logged into my account, and sent many strange messages to my friends in the ichat, I have changed the passwords several times, but it doesn't work.
