Nancy in Louisiana

I had my Norton 360 do a tuneup and diagnostics -- but inspite of what it said it fixed, now I'm still getting long delays, non-responses, and a lot of freezeups. They are not just on the board anymore but have moved into my att email as well. All seemed to come on very suddenly. Was there something new with the ads,especially the "moving" ones that take so long to load? I'm not computer savvy, and am anxious to know if this is my problem or something that came thru from the board's ads.
