Until recently, a Macintosh user was able to remain mostly free of viruses and worms harmful on their computers. This is partly due to the fact that Mac OS X is based on Unix, the operating system is relatively immune to such attacks. Another possible reason could have to do with the fact that Mac has a market share smaller than its main competitors. However, this whole situation is a little changed on 14 February 2006, when a new virus has been developed specifically for users of Macintosh.

A file “latestpics.tgz,” is as tar-video included with Mac OS 10.5. This file Struck first in a popular location for Mac-based rumors and information, visitors to the site quickly discovered that the file is a worm.

If the task is complete, you receive a warning message the next time a file is trying to enter the File Manager.
