    Please check that your computer meets (and exceeds) the system requirements:

    Windows XP Home Edition/Professional/Media Center Edition


    • 300 MHz or faster processor

    • 256 MB of RAM

    • 350 MB of available hard disk space

    • DVD or CD-ROM drive required for all installations

    Windows Vista™ Home/Home Premium/Ultimate/Business/Starter Edition


    • 1 GHz or higher processor

    • 512 MB RAM

    • 350 MB of available hard disk space

    • DVD or CD-ROM drive required for all installations
    Norton is a huge program that has a tendency to lag computers if they are not fully capable of providing the power for it.

    Also, can you open your task manager (right-click the taskbar and goto task manager) and find out the file that is causing high CPU usage?

There are many free anti-virus programs as well. You might try doing a search for "Free anti-virus reviews" in google

Hi,

That is usually the case. Norton eats up a lot of resources. If it is slowing the computer too much, either uninstall it, turn off real time protection or get more RAM for your PC.

My norton antivirus is not runing setup and not unstall also... my computer got email virus also..


install the kasper antivirus software.. it is very protective for mail.. scan every new device(ie.pen drive, cd,dvd) before you access it in your system.. use only one antivirus software in your system.. If you have more than one antivirus software, it will tends to slow processing of the system..

What the disadvantages of norton antivirus and what are the performance norton antivirus


Norton may slow down the performance of your computer,and it is a paid software what i think is instead of going with this you can download any of these free software (avg,avast or avaira) they all are free for one year and do the same thing what norton does without slowing down your computer.

Not opening the norton antivirus software.


hi there

could you be more specific on your problem. if your norton plainly does not work or your auto protect is disabled and you cant activate it, you can just uninstall it and re-install. this usually is the worst case scenario if you cannot be specific on what your norton problem is.

Ok then i guess you should try repairing the NORTON by running the installation again and choosing the reapir option or the next option is to use another anti virus.

you can visit www.avast.com/eng/programs.html and download avast! 4 home edition free edition.
please restart your pc before installing the avast.
after installing try updating and schedule a boot scan by
  1. cutting and pasting this "W62911071H4800A1106-PJY5XRR5" when prompted for the registration key.
  2. click on the menu icon at the top left of the avast window.
  3. click on "schedule a boot scan" and restart your pc

Good luck !!
