Hi. If you downloaded Etcher Portable from the official website (https://www.balena.io/etcher/) it should be clean. If in doubt you can try checking with services that use multiple AVs, for example: https://www.virustotal.com/. I just ran a check there with balenaEtcher portable v1.5.109 and it came out clean. What might be happening is that your AV is guessing based on heuristics, which can return false positives.
