An expired cert is only a risk if you install the software anyway. The other risk is a "trusted" certificate authority issuing a certificate to an unauthorized user, or the signing certificate is compromised. How do you know ANY copy of Windows XP that came on your computer, or you bought in a box from Best Buy is genuine and unaltered? Hint, if you read the documentation, Microsoft tells you how. How many people even bother to check? Double hint, did you read the documentation? Triple hint, this problem exists with all computer operating systems and applications. Sun has the same issue with Solaris, check with Sun how to check if you Solaris CD is geniune. Even mainframe software from IBM has this issue, check with IBM how to check if your IBM mainframe OS is genuine. For the parnoid, did you check the chip in your shiny, new HP laserjet network printer connected to your network is genuine?
