MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is an Excel document containing a VBA macro with an Auto_Open subroutine, indicating it is designed to execute code automatically when opened. The macro's obfuscated nature and the critical ClamAV detection suggest it is a downloader or dropper for further malicious activity. The document body contains generic text related to product information, likely a lure.
