Please answer each of the following [admittedly tedious] diagnostic questions in a correspondingly-numbered list in your very next reply - preferably
without quoting my post:
1a. When (approx. date) did you purchase the computer?

or did you upgrade from Vista to Win7?

choose to install it?

• **C:\Program Files**Microsoft Security Client <=this folder
Select Properties: What is the Created date displayed on the resulting
