A friend of mine had to reformat the hard disk of his PC as it had caught a virus. I told him he should get a Mac as they don't get nasty diseases. He asked me why this was the case.I said that I'm not entirely sure why Macs are, at least, much less susceptible to viruses than PCs. It could be that the operating system (MACOS) is embedded rather than an add on (Windows 2000 or whatever) and is therefore more stable. As I'm not very technically minded that last sentence could be total bollocks. It could be that the people who create viruses do so on PCs as they want to cause the greatest disruption and there are more PCs than Macs. It could be that people who own Macs and are capable of creating viruses for them wouldn't do so because they like their machines so much and are generally more creative and less destructive. I told him that I would put this question to you lot and start an argument.
