Can a Mac be infected with a virus?

People say that a mac can't be infected that's why there isn't a protection thing for macs, but the mac isn't a super-computer that is invincible.

People don't bother to infect Macs because NO ONE CARES ABOUT MACS LOLK

of course mac's can be infected. the reason they usually aren't is that hackers mostly write viruses for pc's (because there are more of them)
yes it can
Yes it can, but making ones for mac is different than making one for a PC. That's one reason why I hate the macs and the commercials.
Yes it can, only not by a virus written for a PC. The two operating systems are different, so a program (including a virus) written for one won't come close to working on the other. Since there are so many more PCs out there than Macs, the psychopaths who create viruses write them for PCs because they'll do more damage. There are therefore very few viruses written to attack Macs.
Hi Dol,

Some day the Mac will be infected with a virus, but it hasn't for the past six years that I've been using Mac OS X. While Vista got computer viruses before it was even officially released.
