For the last couple of days a yellow shield keeps appearing in the task bar. It shows that it is downloading updates, but it never gets past 3%. Then it will disappear, only to reappear later. I have tried to determine what is updating but can't find out what. I have went to Windows update to see if there is an update that I need, but it doesn't show that I do. I have scanned computer with AVG, ran Ccleaner, Malwarebytes, Cleanup. Nothing found. Any ideas or is this just a windows update that is taking a very long time? Windows XP SP3 and horrors, dialup.
