I am just in the process of following your instructions for removing Norton. At the end of your post you said
To eliminate these files for Internet Explorer users, download the Symantec Norton MSI cleanup file SYMMSICLEANUP.reg here and save it to your desktop; if you use the Firefox browser, you will need to download a different file to accomplish this task. Firefox users, please download this file
I use Firefox and when I click on your link to download the file, it opens a new Firefox window and shows me the contents of the file rather than downloading it. Do I need to copy and paste this into Notepad and then save the file?
