Exactly the same thing happened to me with a Toshiba Satellite. I purchased McAfee but to a lesser value than the two week trial preinstalled on my laptop. Not only do I have the continual pop up window the original poster identified, I now have a warning telling me that I am no longer protected (though, on checking I do seem to be covered for anti-virus). When my subscription expires, I will no longer have any truck with this fraudalent company.
