Question Good Free Firewall with Malicious Outbound Blocking?

Also, Do only .exe files can connect to the Internet and scripts must use .exe to be able to connect?

No, not only .exe files can connect to the internet. Other file types, such as .dll and .sys, can also establish internet connections. Additionally, scripts can connect to the internet without the need for an .exe file, as they can use interpreters or scripting engines to execute their code and establish connections.

For scripts, this malware variants usually does abuse "LOLbins" for outbound connections, here this link to check for related files: LOLBAS

I can recommend this tool "FirewallHardening" by @Andy Ful he does still kindly add new LOLbins reported from known malware attack vectors...

FirewallHardening tool

Supposed I am using Default Deny Security Such as Smart App Control.
I will be covered from Executables vector (exe, dll, sys) by having an Outgoing connection because they will be blocked all together.
So I will just need Firewall Hardening Tool to block LOLBins and Scripts.
Am I Cover with this Setup, or Do I need an additional layer to block legitimate executables from connecting to Malicious urls and IPs.
Do antivirus 's web protection cover such threats?

You could install the firewall of Avast free and set it to smart mode.
