VIRUS DETECTED ISSUE WITH ESPRESSIF FLASH DOWNLOAD TOOL v3.9.8
It’s been reported that Windows detects a Trojan virus in the latest download tool (v3.9.8). When this has happened previously it was due to the tool using some Python libraries. The discussion from last year can be found here: https://github.com/espressif/esptool/issues/944.
For now, please use the 3.9.7 version from this site: Flash Downloader v3.9.7
