It is my opinion that this stuff is simply dangerous.
Yes it works, but after a time it stops and almost nobody
bothers to pay for it. They just go along with the fact that
it is running and out of date at their own peril.

Personally I think MS should be allowed to ship its own generic
AV/Firewall just like Linux does. If people want/need something
beyond that then they can pay for it or find another solution.

MS however should NOT be allowed to lock out third party products,
which is usually where they get greedy.
