Just a suggestion why not use regedit to remove all of the syamntic files. I do know that messing with the registry files is tricky and if you do not know what you are doing or looking for it can destroy the operating system and have to do a complete reinstall. Just a suggestion. But, instead of removing norton-symantic first, I strongly recommend removing utorrent and all utorrent files. As you know, utorrent downloads sometines does have malicious software.
Also, have you tried to download Malwarebytes to remove any mailicios files, and CCleaner or Glary Utilities to do a registrt repair.
Again I am just asking, as I still learn from everyone else that has more experience.
