ROVNIX is a Trojan that usually arrives as attachment on spam mails. The spam mail uses social engineering in order to trick the user in opening and executing the attachment.
he attachment is a ZIP archive with the malware file inside. The malware uses at least two extension names: one acting as a decoy, and the other is the actual exe extension. Once user clicks the attachment thru outlook, a copy is created in a randomly-named subdirectory in temporary internet files folder.
The created file remains in that subdirectory even when you exit outlook.exe.
