The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it is a Qbot variant designed to act as a dropper. The detection name implies it likely downloads and executes a secondary payload, a common tactic for Qbot. The file's metadata indicates it is an older Excel document, potentially leveraging older macro vulnerabilities.
