ZDNet reports that AVG, known for its free Windows antivirus tool, is busy developing an OS X version. Possibly. The company isn't sure whether the product will ever launch. Larry Bridwell of AVG's parent company Grisoft said "[W]e have done the [Linux] BSD version, which makes it a little bit easier to port to the Mac. It is in research and development right now to see if it is going to come out."
At this time, OS X remains pretty secure and virus free but one can never tell what time, patience, dedication and a really bad attitude can do to spoil things for everybody.
