Every time I log on appears a window that has a lot of Adobe folders. I have to delete it in order to continue. I do have Adobe 9 downloaded but I don't know about Acrobat reader. Is it telling me the download is incomplete or what? It's irritating and I don't know what to do to get rid of it. I don't really understand what Adobe/Acrobat reader does. Is it really necessary to have it at all? Thanks
