can dvd's be erased

If you run software and your computer is connected to the internet, it's potentially vulnerable no matter what OS you're running.

It is considerably more difficult for a Mac user to accidentally permit a virus; anything that wants to install itself has to request the user enters the master password so to do.

Hence the recommendation for virus protection software -- enough users don't know enough to protect their own machines to make viruses a danger, and now that OSX is gaining significant market share, it's also becoming a more appealing target for hackers and malware.

So far, over two years, I haven't even had a sniff of a virus. There just aren't the possibilities for infection that Windows offers.
