I did this:

mib2events --ueibase uei.opennms.org/vendors/trendmicro/ /root/trend_CM-5.0-v2.mib > /etc/opennms/events/trendmicro.events.xml

and changed the severities (to the best of my belief).

The event file contains this events:

<uei>uei.opennms.org/vendors/trendmicro/trendTestEvent</uei>
<uei>uei.opennms.org/vendors/trendmicro/serviceStart</uei>
<uei>uei.opennms.org/vendors/trendmicro/serviceStopped</uei>
<uei>uei.opennms.org/vendors/trendmicro/componentUpdateSuccess</uei>
<uei>uei.opennms.org/vendors/trendmicro/componentUpdateFail</uei>
<uei>uei.opennms.org/vendors/trendmicro/activeOPPolicyReceived</uei>
<uei>uei.opennms.org/vendors/trendmicro/virusOutbreakAlert</uei>
<uei>uei.opennms.org/vendors/trendmicro/threatFoundActionFail</uei>
<uei>uei.opennms.org/vendors/trendmicro/threatFoundActionSuccess</uei>
<uei>uei.opennms.org/vendors/trendmicro/networkVirusFound</uei>

<uei>uei.opennms.org/vendors/trendmicro/contentSecurityFound</uei>
<uei>uei.opennms.org/vendors/trendmicro/webSecurityFound</uei>

Trend Micro support told me, this events/oids are compatible with all TrendMicro AV solutions (eg. Worry Free, OfficeScan etc).
