Norton Internet Security stopsthe working (XP).I loaded program from CD and was OK for awhile. But now the icon has disappeared from the sys tray (lower right)! When I click on alias icon on desktop- nothing happens. I called service tech who said "some file corrupted" , and sent me a new file that I loaded and it worked OK - for a day (I did a scan - found no malicious malware or virus)! Then, the program vanished again! Also running Norton Utilities. Anyone have this problem before?
