We experienced an issue with not being able to open SpamFighter to enter a product key or manage settings in it’s control panel.
We were advised by the team at SpamFighter to add an exception to our security software AVG.
We had trouble finding the path to the program in Windows10
Path = C:\Program Files (x86)\Fighters\SPAMfighter\*
Issue: Unable to launch SpamFighter options, Enter product key or SpamFighter control panel.
Cause: AVG Internet Security blocking program
Fix: Add SpamFighter exception | AVG – How to exclude file folder or website
Menu \ Settings \ Exceptions \ Add Exception \ Browse \ C:\Program Files (x86)\Fighters\SPAMfighter\*
