If you’re unable to remove Norton security products, there’s a useful tool made available by Norton that will scan your computer for anything Norton related and obliterate it!
We know how annoying it can be when you can’t download a file from an FTP server, so we’ve made the tool downloadable from our domain to save you the bother of hunting down a reliable download. Click here to download it.
You can also click here to go to Norton’s webpage relating to the tool, if you need more information.
As a side note, you might consider switching to the free edition of AVG when you’re done.
