'Fix in Prgress' stuck?

I currently have Norton 360 installed.  My attempts to set up an HP Envy 7640 wireless printer today have got absolutely nowhere and I think the problem may be because Norton has a 'Fix in Progress' and this is throwing out the driver download. However, this has been going on all day.  I cannot stop it, or initialise any type of scan.  Any ideas, short of throwing my computer through the window, which I currently feel like doing? Can I uninstall and reinstall Norton 360?
