I had a recent upgrade to Norton 360 for windows and my pc seems very slow to load now. I also notice that I am getting three Norton 360 icons appearing at the bottom of my PC Screen. Anytime I use Norton 360 or Norton Utilities everything seems to take much longer than before.
Any suggestions as to what is going on please?

You may have different versions of Norton running simultaneously. You should run the removal tool and do a remove only and then reinstall yourself from the website.

Make sure you restart after the removal and after the install. And you might have to run LiveUpdate several times before all updates are complete.
