hehe i guess that first "big and bad" type of virus for mac ( the usual one for windows) is going to become popular very fast and do some damage c mon "no-girlfriend-no-friends-lonely-unsocial" virus makers do the mac thing
The virus' for Mac's are out there but finding "free" worth installing virus protection I have yet to see. If you want control over your Mac look into utility software by micromat works better than Nortons etc. since it was created only for the Macintosh.
Also, if your running OSX on your system buy micromat's Drive 10 utility, it's worth the $70.00
