I am a new mac user and have two windows programs I occasionally will need to use. I just set up a W2k installation through Fusion on a separate hard drive. If I connect to the internet only through OS 10, am I still vulnerable to virus/trojan/spyware because Win is on the Mac? I don't suppose having it on a separate drive helps? Would I be safe if I have the Windows drive disconnected when I'm not using it? If I surf only on my old Win laptop but downloaded a program to install on the Mac, could it be messed up when I boot into virtual windows? I guess I would have to connect with OS 10 occasionally to do upgrades though. All advice appreciated!
