Hi Jacques Bence!
This article anti-virus exclusion suggestion isn't only for old ITMS versions like 8.0, 8.1 or 8.5 but also applies to 8.6.x versions. If you have another location specified for executable files of SMA instead of default, then consider to exclude your custom location in anti-virus as well if anti-virus will doesn't allow to run executables from there.Best regards,IP.
