Thank you for your response. First, let me provide a screenshot:
1. All items are unprotected (i.e., not immunized). Prior to my writing you, I did an "Undo," thinking it would reverse my latest entries. Not so, I now have at the most some 226,177 "Unprotected" items.
2. My "default" browser is IE8 (8.0.6001.18702). I have other browsers on my system. These are FireFox 3.5.7; Opera 9.64; and, Netscape 7.2
3. All browsers are "always" closed during immunization.
4. I did "Undo" the immunization. That is what brought me to the 226,177 "Unprotected" items. The system will not allow me to again immunize. I did try a number of times.
5. As a regular habit, I always use the "Check Again" function on the menu bar.
6. I have clicked many times on the immunization tab. I am no longer allowed to immunize.
7. As commented in item 6 above, I can't immunize a second time.
8. I have AVG Free v9.0.733. I have had AVG for years along with SpyBot S&D.
9. Screen Shot provided at top of page.
10. You referred me to the Forum Message 36272. I read this before emailing my first request for assistance. In particular, I read the Immunization v. AVG section.
Question: As I mentioned previously, I have never had a password as Administrator. Is it possible (silly question) that there is 'bug' in the Microsoft OS, and I am required to insert a password?
Thank you and best regards,
Stan
