The hh.exe process is a legitimate Windows core file. When you open the “compiled help file” (type .chm) by clicking the file or a linked menu item, it will run. By calling the HTML Help ActiveX control, it will open the help file in the Help Viewer.

Microsoft HTML Help products and other third-party authoring software allow developers to use extended directories, shortcuts, keyword searches, and pop-up themes to compile their own ".chm" files.

Sometimes, the malware also uses this file name to disguise itself, and hides it in another location (such as C:\Users\\AppData\Roaming), or uses it as the target of coverage.
