It is usually recommended to run only a single antivirus on a computer system to avoid any risk of conflicts, but the developer of SmadAV Antivirus urges you not to rely on the product alone. You can use this antivirus, but you mustn’t uninstall the one that already exists on your system. SmadAV Antivirus is designed to act as a sidekick to your existing antivirus software. It is made to deal with various threats hidden in flash drives that escape from standard malware detection, but there isn’t any reliable source that reports on how effective the detection is.
