Mac trojan...3 different Mac anti virus programs failled

A vew days back,my macbook air got hacked.
Im behind a router with firewall.
I have all the updates for the mac os.
Mac firewall on.
I have avast anti virus for mac running.
Somehow,i got a new trojan and i found out i was hacked because my mouse cursor was moving on its own over my screen
I installed also bitdefender av and intego virusbarrier.
Non of the anti virus programs found it.

So i installed Private Eye to see whats connecting to the internet.

Found some things i didnt trust after googling for it and deleted them.
Because i was so angry and a bit in panic,i didnt think about sending them to the av companies :(
Now everything is fine according the network monitor.

But it also teached me to never trust on anti virus alone.....A network monitor installed on a mac is a big must.

Hi,

That is to be expected of Macs and Linux boxes I am afraid. The AV products have been traditionaly designed to stop your machine from spreading Windows malware when connected to a Windows network, rather than to protect your machine, which was impervious to them.

I guess the security through obscurity ticket is running out, and they will have to put in a bit more cross-platform effort?

Apple and the software firewall vendors need to take action.
The security through obscurity is a huge danger,because it means,there have to be done major damage first,before Apple and security companies act.
Right now,loads of mac users might have 1 or more trojans and they wont find out,until the damage is done.
There has to come a easy to use software firewall,wich alerts you about any connection made to the internet...just like you have for windows machines.

I just installed TCPBlock,to prefend any new trojans connecting to the internet

you can download it at http://tcpblock.wordpress.com

copy and pasted
TCPBlock is a lightweight and fast application firewall for Mac OS X 10.5 or later developed by delantis.com.
The Mac OS X firewall protects you from connections that come from outside of your computer. But what about the software from your computer that opens new connections to the internet? With TCPBlock you can prevent selected applications on your computer from opening connections to the network.
TCPBlock is implemented as a loadable kernel module which contains all the blocking logic. You can configure it in the System Preferences TCPBlock preference pane or with the tcpblock command line utility. All the configuration changes are made persistent in a configuration file on the hard disk. At system boot time the TCPBlock kernel extension reads its configuration from disk and is ready to go.
It was easy to set up...even for me lol

Guess now i will be safe for any future trojan attacks :)

it's better you can switch over to some other antivirus,
