How to Tell if mpc-hc64 is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\MPC-HC\mpc-hc64.exe or C:\Program Files (x86)\MPC-HC\mpc-hc64.exe. Other locations are suspicious.

Beware of similarly-named files like "mpc-hc64x.exe" or "mpc-hc.exe" from untrusted sources.
Why Is mpc-hc64.exe Running on My PC?

- Filter/Codec Loading: External codecs and filters loaded for proper decoding may keep the process active while a file is open.
- UI and Shell Integration: Tray icons or shell extensions for quick playback control can keep the process resident even after closing the main window.
