Important Notes

• To prevent malware and ransomware from exploiting SMB v1 vulnerabilities, QTS now automatically sets the lowest SMB version to SMB v2 if your lowest SMB version is SMB v1 before this firmware update.
• To ensure your device security, QTS will automatically install Malware Remover after this firmware update if Malware Remover is not already installed on your device. This installation will only be performed once.
