Norton 360 crashed

For the past two weeks Norton 360 has crashed. 2 Norton techs completely uninstalled Norton and claimed some programs were causing the issue.I uinstalled those programs and I have probably spent over 10 hours in chats with them. I have also had at my expense, my computer guys look at my computer. They are stumped. I have used these computer guys for 15 years they are good. In any case today I was told the problem was fixed because it ran perfectly after Norton 360 was reinstalled but sure enough tonight I got the same Norton has stopped working and not only that with the first uninstall my links in outlook stopped working and today after the uninstall/reinstall I type and what I am typing shows up after I am done typing a sentence. Neither of these issues happened before Norton tech support installed and reinstalled their program. I have Norton 360 on two other computers no problems with it and I have mobile on my phone and tablet no issues just this computer. I don't know where to turn for help
