Adjustments have been made to the amsi-client module (12.5.7.202110150) to improve Dr.Web Scanning Engine’s performance in situations when AMSI integration is being used. Recall that due to possible Exchange Server performance issues on machines running Dr.Web software, it is recommended to disable AMSI integration (read more).
