I received the notice yesterday also, but I clicked "NO".
Late last year, one of my computers and the attached external hard-drive got infected from an Adobe update. It was so bad that I had to replace the hard-drive & then update to Window 7 Professional. There is a lot of info on the Internet about computer viruses associated with Adobe updates - be aware, and never allow an automatic update for an Adobe product. If there is an update and you verified that it's safe, go to the Adobe web site and download it. In the past I've received update notices, gone to the vendors web site, and found that no updates were available, but a virus would have been downloaded.
