Thank you for all the help, folks! I really am puzzled about this situation. I have (several times) set updates to manual and prior to this there was no issue. I went back and checked the configuration of the update/install updates and it is still set to manual. I even reset everything again, just to ensure I had not missed something the first time. I have Norton running active with all relevent updates and have run a manual scan with no results. I also ran SpyBot in case something came through Norton and did not find any issues. Basically, I have done most of what you suggested (good, reasonable suggestions, BTW) and the issue still comes up. In fact, this morning I powered up the laptop and let it sit idle for about an hour. During this time it again tried to run update/install - however, it was not connected to the Internet so it stopped. Its times like this when I wish I worked for a company with an IT dept! But, I'm a writer/photographer and work for myself - very much not an IT guru! Thanks again for the help.
