WHY does mcaffe come with updates?

i updated my flash player today and was astonished that mcaffee came with it,

with no option not to have something that causes merry hell with some of the

progrmmes on my pc?

why do these companies try forcing this crap on us norton and macaffee act like viruses

if you uninstall them they leave rubbish behind that take a specialist cleaner to remove

some of us choose carefully whats installed on our pcs
