I have been using Norton products in the past and was always astonished how resource hungry those products were. They surely looked professional which was the main reason why I did install them but they slowed down the system and were really hard to remove from the system as well.
Norton Internet Security 2006 for instance slows down system start of the average PC by more than 40 seconds which is one of the reasons why I think that it is not worth it. A lot of great, resource friendly applications exist that can fully replace most Norton applications and I would recommend to make the switch.
The Norton Removal Tool is helpful because it can remove a failed installation, damaged or unwanted Norton product from your system. I would even suggest to run this application after using the default uninstallation process just to make sure that all files and settings are gone as well.
A lot of computer systems and notebooks ship with (trial) versions of Symantec or Norton products as well and I would suggest to uninstall them using the program if the default uninstaller for whatever reason fails to remove the program completely or at all from the system.
Alternatives vary of course depending on the Norton product that you are using. I suppose the antivirus software is the most common one which can be replaced by AntiVir for instance. Just write a comment if you are looking for a recommendation for another product.
You can download the latest version of the Norton Removal Tool from the Symantec Support website. Here you need to first select your product from the list of available choices - note that security and other Norton software is listed here - to be taken to a secondary page where you find the download link and instructions on how to run the application on your computer system.
You can remove the majority of Norton products using the application, including Norton 360, Norton Password Manager, Norton Ghost or AntiVirus.
You do not need to specify the product that you want to remove as it will uninstall and remove all supported products from the PC. This can be an issue if you just want to remove one product but keep others that you have installed.
So, make sure you do not need any of the Norton products installed on your system before you run the removal tool.
