Is linksys-smart-wifi.exe a Virus or Malware?
The real linksys-smart-wifi.exe is NOT a virus. However, malware authors may mimic names. Always verify location and signature.
How to Tell if linksys-smart-wifi.exe is Legitimate or Malware
- File Location: Must be in C:\Program Files (x86)\Linksys\Smart Wi-Fi\linksys-smart-wifi.exe or C:\Program Files\Linksys\Smart Wi-Fi\linksys-smart-wifi.exe. Any other location is suspicious.
- Digital Signature: Right-click the file in File Explorer → Properties → Digital Signatures. Should show Linksys LLC as the signer.
