I have been a McAfee user for several years and have just purchased NIS2009 because of the excellent reviews in the trade rags. My question . . . I currently have 3 pcs in my home network that have McAfee licenses good thru 7/2009. I am adding a new pc with no security software & want to know if there are any concerns with adding it to the network & installing NIS 2009 with other systems running McAfee. Plan is to eventually replace McAfee with installs of NIS 2009 on all if I like. Also, any issues with installing NIS 2009 after removing McAffe?
