I've never had anything but trouble with Mcafee, whenever I have tried to install it on any machine, so have never actually seen it fully working! I don't think what you are running is overloading anything at all, Michelle, but perhaps Mcafee just takes a while to load all the definitions and settings. I have to admit, since installing Norton 2005, my start up has also slowed, but it's not really a problem, compared to the trouble caused by not having adequate protection. If it's just the start up it's affecting, don't worry about it - just make a cuppa while your PC is starting! 8)
