System tray icon always gray - never blue

Why is the Avast system tray icon always gray?

I just reinstalled Avast 4.7 home edition and the icon was blue for 1 second then turned permanently gray. I think it did the same thing when I first installed Avast a couple years ago. The notice after install says that the icon should be blue and that a gray icon indicates that Avast is “waiting for something”.

All 7 Avast resident modules are active when I run MS Outlook 2003. Without running Outlook only 6 Avast resident modules are active - the Outlook/Exchange module is off. I figure this is normal.

I’m running Win XP with Zone Alarm Pro set with anti-spyware on. I use MS Office 2003. Avast is my only resident anti-virus program. I haven’t had any indications of problems with Zone Alarm.

Try to turn off Zone Alarm because it might block avast form working or download again a new avast program and reinstall.(From my newbie experience)

Yes, it really may be Zone Alarm Pro, but… What AV protection did you had before avast? Have you removed it fully?
