Norton Antivirus uninstalled itself.

Hi, recently my Norton Antivirus uninstalled itself from my computer.

 

I can't find the program anywhere on my computer, I've only found Norton Security Scan. I am running on Windows XP.

 

This happened when Norton detected something about Internet Connection (I can't remember what), and it told me to install Norton Removal Tool. After that, I could no longer open Norton. I restarted my PC, and Norton was gone.

 

Thanks for any solutions.
