HELP! Norton is unremovable

Help, please.

I'm trying to uninstall Norton because it keeps slowing down my computer considerably. It refuses to uninstall from the control panel, so I decided to download the "Norton Removal Tool" (https://support.norton.com/sp/en/us/home/current/solutions/kb20080710133834EN_EndUserProfile_en_us). However, the download to this tool is extremely slow, and is always "interrupted". I earlier downloaded a file that was 2 GB in size and it was quick, but this 875 KB file is taking 4-5 minutes, and then Is "interrupted" and never finishes. It's driving me to the point of insanity, I can't have this broken program stopping me from using my computer. I have no idea what to do now, even manually deleting the files doesn't work, because the program is active and cannot be shut off or disabled in anyway. Please, help.
