Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
Spam fighter hasnt released a version since Windows 7.. So while you could download and install it on windows 10, it may not work as expected. But here is a link to where you can download it and purchase it.
Might I suggest a more modern replacement, Mailwasher has a free version, and if you like it and want more features it also has a paid pro version, and it will work with windows 10
Mail washer serves the same purpose as Spam Fighter, its just a different name/ brand.
If you have any questions, let me know!
