Database Reset Alert

I keep getting the following message appearing in a box:
"Inconsistencies in your sync information for Bookmarks were detected and have been repaired. The next sync for your iPhone , Mobile Me and Safari may take longer than usual"

My question is: Could this be some kind of virus or is it just a glitch with the latest iPhone software update? The message appears every hour or so and has the title; Database Reset Alert.

Any advice welcome. Thank you.

I have this issue on my iBook G4. My G5 and iPhone sync fine over the air (using MobileMe) but the iBook bookmarks won't sync and I get an error saying that there are "inconsistencies" and to verify the iBook and reset the bookmark sync. So far, nothing seems to work.
