    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?

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.

Norton Advantages & Disadvantages


<p>Advantages & Disadvantages:-<br /> <p>Though Norton anti-virus products and its various versions are one of the best protection software, Norton anti-virus software has some advantages and disadvantages.<br /> <p> <br> <p>Advantages: -<br> <p>When Symantec redesign Norton for Widows compatibility, Norton becomes one of the best protection software in the market. With its every release Norton introduced new features or upgraded features. Norton release new versions almost every year. Some unique features of Norton anti-virus are Sonar protection, File Insight, Network Insight, Power Eraser tool etc. which provides more reliable protection against viruses and other malicious code. It can run at background to work silently. It will warn you before running or installing malicious programs. It can protect your computer spreading viruses from your Facebook feed, e-mail attachments. Simple user interface will help you to work more easily. Norton provides PC utility tool to tune-up your pc and Backup and Restore tool. You can solve your problems online from tech support, where you can find answers for possible problems, use-one-click-solution-first to solve your problems manually and customer help desk, where you can interact with tech support personnel for your query.<br> <p> <br> <p>Disadvantages:- <br> <p>While Norton offers variety of benefits to its users, there are also some drawbacks as well. Prior to the 2009 version of Norton anti-virus, reviews claimed that the software required considerable memory to run, this slowed down the overall performance of the computer. Computers that have an old copy installed might experience this resource issue.<br> <p> <br> <p>Uninstalling is another drawback of Norton. If you attempt to remove Norton Antivirus, the uninstallation process proves difficult. This is one area where Norton fails to compete with its competitors, according to PC Antivirus Reviews. Reviewers asserted, "Uninstalling Norton is nowhere near as good as uninstalling McAfee, which sets the standard for fast, clean, easy uninstallation for anti-virus software."

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..

Check if its doing updates or running scans at random times. You can probably schedule them. See if this helps.

System has a virus mbr invected by bloodhpund.mbr how do I delete this. I purchased Norton 2010 but it won't remopve the problem says it needs to be installed but can't get into system to install.


You're Acer probably has Rescue and Recovery™ installed. Rescue and Recovery is a suite of self-recovery tools to help you diagnose, get help, and recover your system.

When you set the Bloodhound heuristics in Norton AntiVirus to it's highest setting you probably ran a virus scan and saw a Norton AntiVirus alert that states that it's detected a potential threat, Bloodhound.MBR. But this is probably not a virus but the recovery software on your laptop.

Solution:

If you have IBM Rescue and Recovery and Norton AntiVirus Bloodhound heuristics are configured to the highest setting, Norton AntiVirus may alert you with a Bloodhound.MBR detection when you run a virus scan. To avoid this, configure your Bloodhound heuristics to the default setting.

To reset Bloodhound to the default setting
  1. Start Norton AntiVirus.
    If Norton AntiVirus was installed as part of Norton Internet Security or Norton SystemWorks, then start one of those programs.
  2. Click Options.
    If you see a submenu, then click Norton AntiVirus.
  3. Click Auto-Protect.
  4. Click Bloodhound.
  5. Click Default level of protection (recommended).
  6. Click OK
  7. Repeat steps 3-6 for Manual Scan.
    In step 3, substitute Manual Scan for Auto-Protect.
  8. Exit Norton AntiVirus.

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.

You got a virus that designed to disable Norton. Do yourself a favour, uninstall Norton. Here a link to an excellent free piece of software for home users. Download it, install it, update it, schedule a boot-time scan, you wil be amazed by just how much it finds & it wont slow your system by being too labour intensive like symantec. http://www.avast.com/

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 !!
