There is nothing wrong with Norton but it will not function if it is installed on top of a previous one or there will be a confliction. You must delete all and only have one.

Why would you want to, Norton is crap!

Do your self a favour, uninstall Norton, download AVG, (it's free,) and turn Windows firewall back on, (Norton turns it off).

If you continue to use Norton you will end up with a virus, it's not reliable enough!
Norton Antivirus is the worst Virus Protection software in the universe. Yes, it gets the job done, but it makes your computer run incredibly slow. I recommend Spy Sweeper with Antivirus. It is cheaper and works much better!!

Hope this helps!
If I were you I'd stay away from anything Norton, it's a power hog! If you're simply looking for a virus scanner try Avast, it's free and easy on the system memory. If you want something more try NOD32, it has great spyware/virus protection, it's not free but one of the best.
In one stupid, insane moment, I downloaded Nortons a year ago. It never worked, was recommended to uninstall, and reinstall. At that time I wasn't on broadband, each time I downloaded, and then got the updates it was six hours each time for something that never worked and which completely messed up my computer. One year later, I am still getting bills to pay for it. A lot of people are recommending AVG as completely free. I like AVG but it is only free for a certain period that I can see and then you have to purchase. If I am incorrect in this please can someone advise me. I personally like Windows Live OneCare, but after using free trial find I cannot purchase online and even if I buy from pc shop, still need to activate online. I believe others have had this problem. However, it is well worth trying.
take it off it kills all machines

use avast instead!
