I have un installed norton on my computer and installed McAfee and now my computer has slowed right down and keeps freezing help what have i done ////????? thanks
did you down load the free norton removal tool to get rid of the norton crap first before you installed mcafee?
if not take mcfee off, use the tool, restart and reinstall mcfee
What is your computer configuration? And what version of macafee you have installed?
alan-r is right, clean out the both of avitvirus with their reputed removal tool.
Now install fresh copy of Mcafee.
