: In the Deep Security Manager, verify that the Anti-Malware policy is actually turned for that specific computer. www.trendmicro.com
Avoid keeping legacy agents running on modern operating systems. Align your agent upgrade schedules to deploy stable DSA versions at least once a quarter.
: If the system is affected by a known Comodo security certificate glitch, open the registry or certificate manager, clean up the corresponding conflicting certificates, clear out the temporary folders located in C:\Program Files\Trend Micro\AMSP\ , and run a clean agent setup. : Open the Windows Services console and ensure
