Hi. I'm a recent switcher so bare with me while I adjust to have a computer that just works. I am considering purchasing Office v.10 Professional w/ vPC. However, I do not currently have any other anti-virus software on my 15"AlBook. Do I need to install Norton or the like, before I use the vPC since Windows is such a vunerable OS? Or because I still am using a Mac, I'll be 99.99% virus-free? Also, after I install virtual PC, will I be able to use any Window's only software/auxillary hardware? Like I said, I recently switched from a 6yo 300MHZ HP desktop to the mid-sized AlBook so please be forgiving in any replys.
