Has anyone heard of this malware - virus for macs?
Are the remedies in the above link proper solutions?

This was one of several Trojans out there distributed with pirated software a while ago. Do you have reason to believe you've been infected with it? If not, simply refrain from downloading pirated software. Further, be careful never to enter your administrator password unless you are installing software from a trusted source and from a well-known vendor. Most Mac software will not require you to enter your admin password to install it -- this only happens when the software needs elevated permissions to modify sensitive areas of the system.

It was a real trap for pirates. From memory that threat came with illegal copies of Adobe programs and Pages.
