MSE: definitions current, but still "potentially unprotected"??

I just noticed that I have the orange "potentially unprotected" flag in my system tray, even though MSE is supposedly up to date. See the date and time info in the pic.

Anyone else experiencing this?

I've seen some update confusion in cases where I did an intervening System Restore, but I have not done one recently.

Going from memory, I thought you didn't get the orange flag until about 48 hours since the previous definition update?

Mike:

I have a schedule set to scan every Sunday. This orange flag started in the last 12 hours somewhere.

I assume my scheduled scans are taking place as scheduled, HOWEVER: I did not begin using scheduled scans until a month or so ago when I upgraded to version 2 of MSE. Prior to that time, I NEVER did scans and NEVER had this symptom. I wouldn't go orange unless auto updates had not occurred for circa 48 hours.

It may well go away if I scan, but I'm not really trying to make it go away---I'm trying to understand why the orange flag now.

More info: just noticed my last scan is shown as 12/26/10---which I cannot explain. At any rate, the flag went orange only in the last few hours, despite it being 16 days since the last scan. And despite scanning having no connection to flag color based on my prior experience.

Here are 2 screen shots, but I'm not sure they are pertinent.

As I stated, my personal experience is that the flag has no connection to scans---the flag is connected to the time since the last definition update.

The larger question now is---how come no scans since 12/26/10, if you can believe that date?

Mike:

Here is the screen shot. There was a definition update failure on Jan 8, but all since that date were successful--including the most recent update only 24 hours ago on Jan 11.

I am wondering if the flagging issue is connected to yesterday's Windows Update---which were unrelated to MSE as far as I know?
