Microsoft Excel.WsF is a malware that belongs to the Houdini-Dinihou infection family. This new variant is starting to appear and differs slightly because it uses a different extension: .wsf (Windows Script File).
Microsoft Excel.WsF malware Description
This programming language allows mixing JScript and VBScript scripting languages in a single file, or other scripting languages. These types of scripts can also be used to link many other external scripts together using a tag system in a similar way to HTML. This provides ample room for evolution for this infection.
Just like the previous variant, the malicious script is encoded multiple times and creates booby-trapped shortcuts similar to the USB shortcut virus.
UsbFix detects and removes this variant. Currently, only this variant and Microsoft Word.wsf (which can be removed by following this link: Microsoft Word.wsf) are known, but UsbFix is configured to detect variants in all their possible forms.
