Just to update all of you who were so nice to help me. ATT Support Plus said that the plug ins which were indicated to be in dire need of an upgrade but I was able to do so for for reasons I, as a mere former Registered Nurse , have no clue about what they were saying, I didn't understand nor could do anything. I was and still to some extent remain somewhat frazzled by this. What we don't understand is frightening and I have just basic computer understanding They (ATT Support Plus) told me that at this time, they do not propose an imminent threat and no viruses or adware in in the system. It took them over two hrs to run all the diagnostic and malware tests. However, I did speak with my installer moments ago. He has his Masters in Compt. Science and is over a few school districts told me that probably the best thing to do was to wipe out the hard drive and install Windows 7. I'm considering this but I don't know the advantages of this system. Do any of you have anything by which you can compare the differences from what I have, Windows Vista Home Basics, and Windows 7, living on a fixed income is difficult but if I have to do it, then I have to do it. Besides my orchids, plants, birds, cats, and nature in general, the computer has enriched my life. As I have a debilitating, rare bone condition called avascular necrosis for which I've had both my knees replaced...and I'm only 55. Please, no sympathy. That's not something for which I'm fishing. I just wanted you good people to know a little about me and my circumstances. If any of you wish and have the time, I'd so appreciate your input on this. Kindly, Lee
