Hi Loose rivets,
I've used Secunia PSI now for about a year, on an XP machine and a Windows7 64bit laptop. It's good at keeping software up to date. On occasion you have to manually update sofware if Secunia is unable to do it automatically (most of the time it does though)
I don't know what that link is in your post, but I also use microsoft Security Essentials and am very happy with it's protection for viruses and spyware.
