The JavaScript is heavily obfuscated, making its exact function difficult to determine, but the CLAMAV_DETECTION heuristic suggests it is malicious. The obfuscated JavaScript likely attempts to download and execute a second-stage payload. The authoring application information is also included as a potential IOC.
