Browsing through the software on Apple's online store, i saw Norton/Symantec and one other company that I did not recognize sold antivirus packages for Mac. Could someone please explain ? Just don't give me the marketing line. There may be very few viruses for Mac's since virus writers also look for market share. I would expect that it may be harder on a Mac - after all, many Windows viruses are cases where some kid just copied someone else's work available on the net. But I have always had a hard time believing that Mac's are impossible to infect. I know a Windows virus is not a risk, but couldn't an OSX virus be written ? I'm not trolling. I am a longtime PC user who is thinking about buying a mini Mac. I don't want to waste money on antivirus software if it is truly pointless, but seeing as Apple sells it in their store, it must have some value. By selling it, they are implicitly acknowledging that Macs are at some risk. If they say it is impossible, then they are ripping people off by selling software with no content.
