Hi Nick
I am Dave, an Independent Advisor, I will help you with this . . .
Helper.exe, can be associated to may applications, like Firefox, uTorrent, BitTorrent . . .etc.
Open File Explorer, then in the address bar, paste this and press Enter:
%appdata%\Microsoft\Windows
Is that Helper.exe file not in that folder?
If it is, then delete it . . .
Otherwise:
Click the link below to download a small free utility that does not require installation
https://docs.microsoft.com/en-us/sysinternals/d...
When the file downloads, unzip it.
Depending on your system, run Autoruns or Autoruns64 as Administrator
Type helper in the search box in Autoruns
Does that find any results?
