If I use Windows on a Mac via Bootcamp, am I prone to get a virus even if I do not use the internet? What if I'm connected to the internet via Wifi, ethernet, broadband, etc., but not using the internet (using Firefox, Safari, or Explorer)? Even if I use the internet, is it still possible to get viruses even when I'm on trusted websites such as google or yahoo.com? It's not like these are suspicious websites. I guess I'm wondering how viruses, in general, get into a computer. Thanks.
