About Comodo Firewall

Can it be used along with an antivirus? since it can still detect malware.

Yes. If you add the C:\Program Files\ folders of both softwares at each other’s exclusion settings. Also setting all .exe files from your AV folder as trusted in Comodo File List.

If your AV have a Behavior Blocker, disable VirusScope in Comodo or vice-versa. It will also be necessary to add your AV folder as an exception at “Don’t detect shellcode injections in these applications” in Comodo’s Miscellaneous Settings.

If you trying to run Comodo Firewall alongside Kaspersky Free Antivirus or Bitdefender Free Antivirus, install the AV first then Comodo.
