workarounds: The attack surface can also be eliminated by disabling the Enable advanced scanning via AMSI option in ESET productsâ€™ Advanced setup.
However, ESET strongly recommends performing an upgrade to a fixed product version and only applying this workaround when the upgrade is not possible for an important reason.
