to all fellow rcloners, i have create a short howto guide to workaround the issue.
https://forum.rclone.org/t/rclone-exe-is-a-virus-workarounds/26223
- whitelist the threat using windows defender, three ways, listed from least secure to most secure
- modify the rclone.exe - changing a single byte and as a result change the hash.
- upx the rclone.exe - which will compress rclone.exe and as a result, change the hash
