The directories & files a re created 2 at a time in the root directory of each of the HDDs attached to the computer. They remove easily. The directories always start with an a, b, x, y, or z & end in a 2 to 3 digit number. The files inside almost look legit for a program. When the directory is deleted it stays deleted for 2 to 5 minutes & then is recreated. When they do reappear they usually are marked hidden.
