Once this document is opened, another file called doc.doc is loaded. It contains embedded HTA script, detected by Dr.Web as PowerShell.DownLoader.72.

During its execution, PowerShell.DownLoader.72 calls an interpreter PowerShell. It processes another malicious script that downloads an executable file to the attacked computer.
