Its possible they are updating that much I've seen weeks on Mac version they updated every couple of Days. Seem Flash is an easy mark to tinker with and put in nasties.
If Flash Player want to update that often, that indicates that the updates do not succeed.
What is your current Flash Player version?
Can you post the contents of the FlashInstall.log file from C:\Windows\system32\Macromed\Flash
