Is rslsync.exe Safe?

Yes, rslsync.exe is safe when downloaded from the official Resilio Sync site (www.resiliosync.com) or Microsoft Store, and used as intended in a typical home or business setup.

Is rslsync.exe a Virus or Malware?

The real rslsync.exe is NOT a virus, but malware may mimic names. Always verify signature and location.

How to Tell if rslsync.exe is Legitimate or Malware

  1. File Location:: Must be in C:\Program Files\Resilio Sync\rslsync.exe or C:\Program Files (x86)\Resilio Sync\rslsync.exe. Any rslsync.exe elsewhere is suspicious.
  2. Digital Signature:: Right-click rslsync.exe → Properties → Digital Signatures. Should show "Resilio, Inc."
  3. Resource Usage:: Typical usage is 2-15% CPU per active folder, 120-360 MB memory. Extremely high usage when idle is suspicious.
  4. Behavior:: RSLSync should run when the app is active or when a sync is scheduled. Continuous background activity with no folders configured can indicate malware.

Red Flags: If rslsync.exe is located outside the program folder (e.g., C:\Windows\Temp, AppData\Roaming, or System32) or lacks a valid digital signature, scan immediately. Beware of similarly-named files like “rslsync32.exe” from untrusted sources.
