Thanks to the comment by Sathya, I found that I have /Applications/Akamai, which was put there by an Adobe installer.
This is not malware, and there is proper documentation and even management tools in the folder:
The Akamai NetSession Interface runs as a service to manage downloads and to
let you manage the download process. It was installed on your computer when you
downloaded content that uses the service to provide secure, high integrity
downloads of large files.
The NetSession Interface supports downloading from a central source and between
peers. When peer-downloading is enabled, your computer can serve as an upload
source for other computers -- without adverse impacts to your computing.
Peer-to-peer downloading can provide faster, more effective downloads.
The NetSession Interface contains no adware or spyware, is safe and secure,
uses minimal resources, and provides you the ability to manage and control its
actions, including the ability to uninstall it if you do not want it on your
I am going to uninstall it anyway.
