Hi, I've only just bought a new mac having been using a PC and am running Parralels on it, I was just wondering, before I start downloading anything, what the risks are of viruses. I gather that viruses are a lot harder to come by on Mac OSX than on windows, so I assumed that if I'm going to download anything off the internet I should do it on Mac OSX and not Windows. If I did get a virus from running windows on parralels, could it corrupt my Mac OSX or would it be isolated to the Windows virtual computer on my mac? I'm pretty new to apple, so any help would be greatly appreciated. Cheers!
