text: anti virus programs for macs.  mac users only please.? do i need an anti virus program for my wifes imac g5? i just read macworlds newest mag and even the editor says he still runs his mac without one but this issue is all about making your mac more secure. is two or three viruses written for our mac's worth the drag an anti-virus program places on our imac's? window xp runs fast and somewhat stable till you load the firewalls, anti adwear and virus programs. do i really want to go there with her new mac? she is a smart experienced computer user and is the only user of her computer as we are empty nesters. what has been your experiences with this? thanks for any help. under our old system 9, we didn't worry much about such things. with os x, it opened the door a bit. exposing us to unix weakness. while far less than windows users, there are those occasional little viruses.  i should say yes, but in truth... most of us (the people i know) don't. just make sure you download and install any updates from apple  however if you choose to run windows on her mac, yes!!!!!!!!
