you can copy limewire start-up program address and then go into mcafee and try to place the address to limewire into the allow list ?
this should be where limewire is on your puter
"C:\Program Files\LimeWire\LimeWire.exe"
now copy it and place it on the allow list in mcafee.
Hope this helps but if not ask me personally andi will find a way to fix it or a reason why it will not work, Mcafee should be able to run while you use limewire, i am always getting notices of attempted hackers while downloading music ? so dont turn mcafee off,
