An aws-cdk construct that uses ClamAV® to scan newly uploaded objects to Amazon S3 for viruses. The construct provides a flexible interface for a system to act based on the results of a ClamAV virus scan. Check out this blogpost for a guided walkthrough.
Docker: The ClamAV Lambda functions utilizes a container image that is built locally using docker bundling
This project uses projen and thus all the constructs follow language specific standards and naming patterns. For more information on how to translate the following examples into your desired language read the CDK guide on Translating TypeScript AWS CDK code to other languages

sc.add_source_bucket(bucket_3)When ClamAV publishes updates to the scanner you will see “Your ClamAV installation is OUTDATED” in your scan results. While the construct creates a system to keep the database definitions up to date, you must update the scanner to detect all the latest Viruses.
Update the docker images of the Lambda functions with the latest version of ClamAV by re-running cdk deploy.
