Windows Defender detects and removes this threat.

This threat uses a Microsoft Office vulnerability to download and run files on your PC, including other malware.

It runs if you visit a website, use an Microsoft Office document or .rtf file (Word document), and have a vulnerable version of one of the following applications on your PC:

• Microsoft Word 2003 SP3
• Microsoft Word 2007 SP2 and SP3
• Microsoft Office 2008 for Mac
• Microsoft Office 2011 for Mac
• Microsoft Compatibility Pack SP2 and SP3

It is most often distributed through emails, but it might also be hosted on a website or distributed on network shares.

You might get an alert about this threat even if you're not using a vulnerable version of the application. This is because we detect when a website or file tries to use the vulnerability, even if it isn't successful.
