I constantly have problems with my Norton antivirus. If it actually launches (it often just has a pop up saying Pending.... and nothing happens) it fails to detect viruses. I have had to use the free Malwarebytes tool to detect and remove a virus that sailed past Norton, even though I have the paid Norton 360 Premium version from Symantec. I have had my account suddenly show that I am on a trial that has expired, even though I have paid a years subscription, so the computers have no antivirus cover and they have to start the whole process again from scratch (once when they were talking me through the process of uninstalling and reinstalling it, they omitted to uninstall a part of the software and left my computer unable to connect with the internet - Apple found the problem after 3 hours with their support even though Norton said it couldn't be anything to do with them and refused to help further). I can't contact an agent on the 'phone us' option as I fill in my details and press NEXT - and get taken back to the main contact us page. I can't contact them on chat because I never get my turn in the queue. I get to No1 in the queue or to "An agent will be with you shortly" then suddenly I'm back at 7th in the queue - and so on, never ever getting to speak to an agent. If I could give them zero stars, I would.
