Can't help very much I'm afraid because, when I ran it, I was too dumb to work out how to persuade it to stop scanning an old hard drive I have installed which was stuffed with out of date programs! I get a clean bill of health when I run the online scan so I'm happy with that.
As for your other question, I personally would get the new version(s) direct from Adobe. Before doing that you should run the special uninstaller from Adobe, as that is supposed to be the only way to get rid of old versions properly;
http://kb.adobe.com/selfservice/view...4157&sliceId=1 (There are some specific points for IE users to be aware of in the instructions for using the uninstaller)
If you only use IE you will only need the Active X version of the plugin which, confusingly, has the same version number, and is about the same size as, the version for Firefox, Opera etc. Here's the link for the IE version;
http://get.adobe.com/flashplayer/ (uncheck the Google toolbar unless you want it).
Read the installation instructions carefully, you probably need to be online for the install to complete properly. I can provide a link for the other version if neccessary.
PS. I'm not certain the uninstaller works with old Mactomedia versions, so you may need to do that via Add/Remove
