I use Norton AntiVirus. Normally, when I right click on the Norton icon in my SysTray I get the option to "Open Norton AntiVirus" which gives me the typical Norton window with several choices including running Live UPdate, Scan, etc. Just in the past couple of days, when I click on that SysTray icon instead of the normal window coming up I get a smaller window titled "Windows Installer" and in it reads "Preparing to Install". Nothing happens for about 30 seconds and then the window vanishes and I'm right back to my desktop. Anyone with ideas? I have a 1.5mhz processor and am running XP Pro.
