With TrendMicro Antivirus Agent/Server-related software installed on Windows agent machines, the Kaseya Agent fails to check into the VSA, even after the agent machine reboots. The Kaseya Agent Service is not able to be stopped as well. How do I resolve this?
Trend Micro Antivirus software has some additional features which act as a firewall and do not allow the Kaseya agent to check into its specified VSA.
Disable the behavior-monitoring service in the TrendMicro Antivirus software.
