Hi, Itscruxx,
It sounds like your Antivirus may have updated, and is treating the Honorbuddy.exe as infected. Please check in your AV's quarantine folder. If you don't think you are running an AV, you are running Windows Defender, and need to look there.
In the worst case, you can re-download and re-install Honorbuddy. But before doing so, don't forget to make the entire Honorbuddy folder an exception to your AV.
cheers,
