Hello, If you are downloaded Hand2Note from our official site using this link:
http://h2n-uptoyou.azureedge.net/mai...eInstaller.exe there are no viruses in it.
It is likely a false positive from your antivirus/Windows Defender. You should try adding Hand2Note to the antivirus exclusions, or disable it.
The \Hand2Note\integration\ folder contains modules that are required for the HUD to work.
