You are absolutely right -- my full-scan problem has been corrected with today's update to 16.0.R26! No need to uninstall/reinstall (which I didn't do anyway, once you mentioned that the issue was being referred for advanced attention; I did Custom Scans on my hard drive instead, which worked out well). Thank you for getting back to me on this; I had already tried a full scan this afternoon, just to see if the new update fixed the problem (which it did!), then read your message to me. It was very kind of you to let me know.
