I installed parallells 6 today and installed windows 7 'cause Im tired of all the crap chat clients (except ichat, but sucks because no msn) on the mac. Also with the lack of webcamming options. Tried skype, amsn, adium, ichat and I could not webcam with this one person. Both of our webcams were working. Had to use a web messenger to be able to webcam. Anyway, do I need an antivirus for running windows virtually?
