Antivirus Events and Logs Overview
Use this page to view information about security events based on antivirus policies. The event viewer provides a view of all antivirus events and the action taken by the virus scanner.
The antivirus scanner inspects files transmitted over several protocols to determine if the files exchanged are malicious (for example, viruses, Trojans, rootkits, and worms).
Using the time-frame slider, you can quickly focus on the area of activity that you are most interested in. Once the time range is selected, all of the data presented in your view is refreshed automatically. You can also use the Custom button to set a custom time range.
There are two ways to view your data. You can select either the summary view or the detail view.
Antivirus Events—Summary View
Click Summary View for a brief summary of all the antivirus events in your network. The top of the page has a swim lane graph of all the antivirus events against the blocked events. You can use the widgets at the bottom of the page to view critical information such as top blocked protocol commands, top reasons, and top sources. See Table 1 for descriptions of the widgets in this view.

Antivirus Events—Detail View
Click Detail View for comprehensive details of events in a tabular format that includes sortable columns. You can aggregate the events using the Group by option. For example, you can group the events based on source country. The table includes information such as the event name, Content Security category, source IP address, source country, and so on.
The Legacy Node option is displayed in the event viewer after the legacy log collector node is added on the Logging Nodes page. We’ve added the legacy log collector support only for read only purpose to view existing log collector data. New logs should point to Security Director Insights VM as the log collector. Select the Legacy Node checkbox to view the existing log collector data. When you clear the Legacy Node checkbox, Security Director Insights log collector data is displayed.
