I'm fed up with Norton

I have been using Norton on two computers  ( Win 7) for over  4 years and  before that 10 years on  XP and other earlier Windows, and I have had almost nothing but trouble.  Not functioning, not launching , losing  the proxy server leading to   many repeated  downloads, and reinstallations, deletions, chat time  on and on. Hours and hours of my time. Sometimes the product launches, sometimes not; sometimes the icon appears  at the bottom of my screen then disappears on its own. Even when it runs, I still get  screen locking  hacks or malware and countless other unwanted  interventions by pirate or  spam artists. I just can't rely on it to run, nor to  protect me.

Is it unreasonable to expect a program to run smoothly and seamlessly? Especially  after Norton has be in the market so many years  ?
