I am also having the same problem,
I have had some malware(s) that I THINK i have removed but not sure, however some of the effects are happening still..
This seems to be a clever programme as when opening macafee it shows below
however when you go into the options it shows that it is disabled:
as described by Kingpicollo when you click to turn it on it instanstly goes to off. Quite concerned about the fact that Macafee seems powerless to whatever has infected it and now seems to be able to change how it displays and works without giving any indication that it's been affected.
