Keep removing and re-installing Norton Internet 2014 to no avail

Dear all

 

Hope I've posted this in the right place. Purchased Norton Internet Security for my laptop last year and for a few months it worked ok, though in the last few weeks it hasn't been working. I can't open Norton Internet and the solution says to remove and re-install.  I've done this about a half dozen times and each time things are ok for about 2 days and then the same thing happens ok. I'm getting very fed-up and thinking of cutting my loses. Any suggestions?

 

Thanks
