Bitdefender with Zonealarm high CPU usage

I use free Bitdefender antivirus with free Zonealarm firewall. I switched from Kaspersky and comodo cuz they used to much of my resources (almost 100% cpu). I deactivated Zonealarm and cpu usage dropped to normal levels. Should I remove zonealarm? Seems this combo is not compatible. Bitdefender seems to recognize some of zonealarms files as a thread and blocks them (suspicious behavior). Not sure what to do here. Any advise?

If it helps, for a free firewall I use this It's very light on resources and works in-conjunction with Windows 10 firewall.

Wait... Zone Alarm is still a thing?

Just use Windows Defender and you should be fine.
