After installing the upgrade of Adobe Reader to version 10 and then restarting computer, the Norton 360 task tray icon shows a gray circle with a white slash. The product Norton 360 still opens, I can run N360 LiveUpdates, and I can run a scan. I do not know if the gray circle with white slash represents a problem or not. The product still seems to work. I'm interested in any advice or warnings. (Also note, I opened Norton 360 from the desktop icon - did not yet try using the task tray icon).
(Yes, I DID remove the checkmark on the Adobe Reader 10 download page about the MacAfee Scan).
