Doubt about configuration help text

I’ve just installed Comodo firewall only (no antivirus) with optimum proactive defense in a clean new PC, the active configuration is COMODO - firewall security, reading the help I found this paragraph:

“Firewall is always set to Safe mode. But according to the malware scanning results performed during the setup process, if no malware is found, Defense+ is set to Clean PC mode. Otherwise, the default is Safe mode.”

Well, after installing, the Defense+ was set to Safe by Comodo and no to Clean, Does that mean that malware was found in the setup process??

That paragraph really confuses me…

Thanks
