Once in a while I notice major internet activity on my DSL modem. No one in the house is downloading anything, so I check Activity Monitor and the process named "softwareupdatecheck" seems to be the culprit. This is not Software Update. It indicates that it is downloading mostly but uploading too. I am not sure how to find out any more info about it. Anyone know who or what program is doing this and why? This is not Adobe or Microsoft checking for updates either -- as far as I can tell. Their updates are indicated in the dock with icon and softwareupdatecheck seems to give no indication there. Should I be concerned?
