How to know if you have been infected with Mac.Backdoor.iWorm

A new thread has been discovered and has been dubbed Mac.BackDoor.iWorm. Affecting several thousand iMacs and Macbooks the malware opens a port on your computer and tries to make a connection to a server which it finds browsing comments in the /r/minecraft (the popular game which recently got purchased by Microsoft) subreddit of Reddit (a social network) that have been left by the hackers (source). Hackers mainly use the infected computers to send spam emails, mine bitcoins or create DDoS attacks.

    Why not create your own JavaW at the correct location and change the permissions so no one can write to it, thus blocking the infection, not just alerting you to it’s presence?
