Some antivirus programs may flag unknown or unsigned EXE files — this is a common false positive for small, portable tools. You are encouraged to scan the file with VirusTotal or run it in a sandbox if desired.

The tool only performs TCP connection checks and banner reads — it does not exploit vulnerabilities or perform intrusive actions.
