About Active Content filtering

Active content contains programs that can execute automatically without user’s knowledge. Active content can be used to execute the malicious code. Symantec Protection Engine removes active content (content disarm) such as scripts and attachments from certain document types.
Symantec Protection Engine filters active content from your documents; however, it does not determine if the active content is malicious or clean. It deletes the content based on the content type.
Active content filtering is disabled in Symantec Protection Engine by default. You must enable it if you want to filter the documents with active content.
