Lisa is right, it is legit, McAfee just confirmed it is a genuine download. This version of Mcafee is provided to corporates for up to 20-40 users at a time. The service is registered in the name on an 'administrator' and you will simply be one of many users on that system. The only difference between this and the home version is that you will not be able to manage renewal in 5 years, for £3 for 5 years I'm happy with that.
