Well i feel kind of bad about this but it didnt cause any harm. I burned a Dvd full of stuff for a friend, and unwittingly gave him a few infected files. Now i dont have any sort of antivirus software on my iMac because i dont need it. But when things like this happen i wish i had one. My question is has this happened to any of you and do you have any suggestions? I refuse to by Norton ( 50 bucks for the off chance this happens again? ).
