I've had a series of problems since I installed the updated antivirus program. I am running Windows XP on an HP Pentium 4. First, the icons on the desktop and on the toolbar no longer work. I am accessing firefox and this site through the task manager. I tried uninstalling the new norton community program, and while I was able to do so, I was no longer able to use the "go back" or system "revert feature." And, I kept getting a warning that I - now - had no antivirus protection. So, I tried re-installing the new program. Again, at first it seems to work, then the performance degrades. So, second, the computer runs much more slowly. I noticed that the clock is running very, very slow. It's now off by around half an hour. It was always on time before. And, third, as I was registering so that I could post this comment and ask for suggestions on what to do, my computer just went blank and then robooted. I can't access the re-boot log because (1) the icons don't work, and (2) I wouldn't know what to look for even if there were something I could do to access it. Suggestions?
