Voodooshield is very bad, without self-protection cerber ransomware deactivates it and manages to pass Voodooshield, in this case COMODO Firewall is much better.ok, Panda Free AV and Comodo Firewall....In my own personal oppinion Panda Antivirus alone is not really great and its detection update in Virustotal is a little bit slow. I have never use Comodo firewall before..but based on the name it seems like you are focusing on Antivirus and Anti Network Instrusion combination. If it is what you are looking for from this two product..i'd say it is a good one. But if your concern is more on zero-day and unknown malware and sophisticated malware, if Comodo does not offer Application Whitelisting and Sandbox technology...then it is not the right one. You can try Voodooshield + Panda Free AV or like my home computer is protected with AVG + Voodooshield. What you need to combat against new, unknown and most sophisticated malware/ransomware while protected against all known malware - is VoodooShield + any free AV. It is very rare these days hackers hack your ports directly..instead, they use targetted attacks through emails, or websites that will trick you to download and execute malware. Seriously, it is up to you as long it has all the features that you want and can really protect you against zeroday or fresh malware.
