    Try to scan your PC for malware / virus programs.
    Do it with Malwarebyte's / Avira (or other anti virus software you got)

    *Make sure that these software's are fully updated, and that you're running this scan while you're in safe mode.
  2. I've scanned using Malwarebytes updated, it detected some stuff:

    I killed them, still 100%~ when accessing my Documents.

    Malwarebytes' Anti-Malware 1.46
