In the past weeks, Trend Micro has released Scan Engine (VSAPI) 12.000 to most products and one performance issue was reported in ServerProtect. Thus, Trend Micro decided to defer ActiveUpdate (AU) for Apex Central / TMCM until April 21, 2020. This is for customers who are using Apex Central / TMCM to update their Trend Micro ServerProtect.
If you are using Apex Central / Control Manager as the update source of ServerProtect, refer to this KB article to manually update ServerProtect before April 21, 2020.
