How to Tell if slimjet.exe is Legitimate or Malware

File Location:: Must be in C:\Program Files\SlimJet\SlimJet.exe or C:\Program Files (x86)\SlimJet\SlimJet.exe. Any slimjet.exe elsewhere is suspicious.
Digital Signature:: Right-click SlimJet.exe in File Explorer -> Properties -> Digital Signatures. Should show "FlashPeak, LLC".

Red Flags: If slimjet.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when SlimJet isn't open, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately. Watch for similarly-named files like "slimjet.exe" in untrusted paths.
