I have MSE installed on a home computer (32-bit Vista). The system tray icon is perpetually orange and unhappy that my system is "at risk" because the scheduled scans fail to run. The computer is left on at the times when the scan should run, but so far the scheduled task has never run. Meanwhile I have FEP (essentially the same product, right?) installed on my office computer (64-bit Win7). The scheduled scans run just fine, and the tray icon is a nice happy green. Any ideas? -- Helen Read Senior Lecturer Mathematics& Statistics University of Vermont
