-Некоторые AV (Kaspersky, Microsoft Wacatac.B!ml, Ikarus Trojan.WinGo.Agent и др.) часто помечают **любые** Go-бинарники с сетью и сменой системного прокси.
+Некоторые AV (Bkav, Microsoft Wacapew/Wacatac, Ikarus Trojan.WinGo.Agent, Google, Trapmine) часто помечают **любые** неподписанные Go-бинарники с сетью и сменой системного прокси.
 
-В 1.7.0 уменьшили «подозрительные» паттерны:
+В 1.7.1 дополнительно:
-- нет скрытой загрузки cores при старте;
+- обновление только скачивается в `Downloads` (без самозамены exe);
-- нет `.bat`-самозамены с `del /f` + hidden detached `cmd`;
+- нет автопроверки обновлений и тихой загрузки cores при старте;
-- обновление через `Navis-pending.exe` + явный флаг;
+- нет вызова `netsh winhttp`;
-- Windows application manifest (`asInvoker`);
+- Windows manifest + metadata EvilFox.
-- metadata компании EvilFox / Product Navis.
 
-Если Defender/KAV ругается: добавьте `Navis.exe` в исключения или отправьте файл как False Positive вендору. Надёжнее всего — подпись Authenticode (code signing certificate).
+Если всё ещё ругается — отправьте файл как False Positive:
+- Microsoft: https://www.microsoft.com/wdsi/filesubmission
+- Google: https://safebrowsing.google.com/safebrowsing/report_error/
+- VirusTotal community vote: «False positive»
+
+Полностью убрать ML-детекты обычно можно только с **Authenticode** (code signing).
