Today I opened OneDrive by accident, since I do not use it. To my surprise, inside there were unknown folders, in foreign (to me) languages. Namely, "document" and "photo" folders in Korean and a shortcut in French with the meaning of vault/safe.
Mind you, these are all completely foreign to me. Judging by the status icons, the folders are online-only. The shortcut had been created at the same time as the first folder. Also I cannot open the file location of the shortcut.
Could this be a sign of potential infection? If not, how did these come about? Please see the screenshot below.
