trying to delete a Symantec AntiVirus file version 10.1.0.396

having dificulity deleting my old norton, cause i forgot the key code and so i started to delete each file individually and i have managed to delete them till just this one file and the description is Symantec AntiVirus file version 10.1.0.396 and it is digitally signed by Symantec Corporation...

 

I want to rid my comp of the old norton so i can install a new norton provided by my service provider ( comcast ) ...

and its totally been a pain in my arse ...

 

pleases can anybody help ? ive tried all the removal tools and it just keeps telling me that a 2009 or later norton has been detected and must be removed via add/remove program ... i look in my add/remove program and theres nothing related to norton, ive gone as far as to search everything under norton and symantec and deleted everything individually...

 

thanks,....
