Deleted symatec/norton, didn't uninstall, still get reminder to renew subscription

Hi,

 

I had 

Norton AntiVirus 11 for Mac

OS X 10.4.10 or higher

 

For some reason I deleted norton and semantec files via trash rather than uninstalling. There is no trace of it anywhere (that I can see). 

 

Yet every time I connect to the internet, I get a reminder to renew my subscription. I don't want to renew.

 

Can anyone tell me how to get rid of this renewal notice?

 

thanks!
