Because that is my prerogative. Blasting McAfee belongs on independent forums or in a letter to headquarters (see About McAfee link at bottom of the page) not here. This is a forum to ask for help, not to air grievances.
Nuisance posters will be banned.
Just because some people aren't happy we can't allow them to take over the forum. Ask in a normal civilised way for help and we will give it, but don't come here with the sole intention of letting off steam as that will result in no help at all, and don't revive dead threads.
Believe me, it's happened before and no doubt will happen again.
