Crack is for Norton Internet Security 2009 & Norton AntiVirus 2009. It just resets the trial period every time you start your computer. It is only for Windows XP (x32) & Vista (x32). There is a nag screen when you open up Norton 2009.
1. Install Norton 2009. (It would be best if you are not connected to the internet.)
2. Install crack and restart your PC.
3. To remove, just use the uninstall.
