Interpretation and response
This event is recorded as “Real-Time Anti-virus”. Review the originating log and the affected host or service to determine whether the activity was expected.
An OSSEC/HIDS event records or correlates activity. Blocking depends on the originating application and any separately configured Active Response policy; an alert alone does not prove that an attack was blocked.
Documentation
The following guidance was migrated from the historical wiki and reviewed against the rule definition. Legacy ASL product names and interface instructions refer to the versions documented then. Use the current metadata above and your installed configuration when interpreting thresholds, notification settings and response behavior.
Description
This is a generic (level 3) event to collect real-time AV scanner events from Clam Anti-virus.
What you should do
No action recommended. This is a generic catch all “bucket” for Clam AV real-time events, that include initialization.
Troubleshooting
False Positives
A legitimate event may still trigger this rule. Review the surrounding activity before deciding whether it is malicious.
Tuning Guidance
This rule can safely be set to logging type “no” to prevent it from being reported in the event viewer. Do not disable this rule, as it is a requirement for other IDS related rules.
