Windows Firewall Control (WFC) by BiniSoft.org

The two Windhawk modules "Modernize Folder Picker Dialog" and "Better file sizes in Explorer details" caused the issue. I found the feature to exclude processes from these modules and added the two WFC executables. Now WFC runs again.
Thank you!

 

Security is critical. Thank you for staying on top of it.

WFC firmly remains on my all time Top-5 favourite software list. With or without the Malwarebytes badge.

 

Excellent redo for safety- Applause

 

Yes, excellent work again! Thank you!

 

Something is going on with the Rules Panel unfortunately. I noticed these:

a) It gets stuck frequently on "Please wait" (black box in the middle). Just try filtering or refreshing a few times.
b) It won't export Rules. No file is created (no error message). I didn't try Import.

6.22.0.0

 

Just tested b): export works here.

 

6.22.0.0 installed well, and export rules works here also.

 

Great work, alexandrud! Thank you...

 

Please check again my updated post from here. I made some updates to it. If WFC event log contains any 112 event IDs, check the Details of the error. It should give a hint of the problem.

Later Edit: I was able to reproduce this on my machine. Export failed because wfcUI.exe had this file injected to it:

System.Exception: Suspicious module detected. ProcessID=6044 ProcessName=wfcUI ProcessFile=C:\Program Files\Malwarebytes\Windows Firewall Control\wfcUI.exe ModuleName='FileSyncShell.dll' ModuleFile='C:\Users\user\AppData\Local\Microsoft\OneDrive\21.220.1024.0005\FileSyncShell.dll'

Ok, I will revert this change for now until I find a better way to deal with this. I tested this for two weeks on my machines and there is always something that breaks when it comes to security hardening.

 

Same for me, I got both errors 112 and 222
112

I will have to rethink this. I will make any new implementation of it, optional and disabled by default. In software development, even simple things that should be straight forward can lead to unexpected side effects triggered by external software.

Thank you for your feedback and your support,

P.S. Exporting rules should work again and all other features.

 

I've just autoupdated from 6.22 to 6.23 and exporting rules works, thank you for the fix. I had to repeat the same process described in my previous post (Exit from WFC and in an elevated CMD window, execute: wfc6setup.exe -update) because opening main WFC panel in 6.22 showed a almost blank window, only titlebar was visible.

 

These updates reminded me of a fairly recent, minor issue. The update prompt appears on the bottom-right but part of it is off-screen:



I can easily drag it to reveal the bottom options, but its new position is not remembered on the next update and it'll keep appearing partially off-screen.

 

Auto Updated to 6.23.0.0 here as well and exporting rules works also. Thanks for the fix.

 

If I understood correctly, WFC now blocks DLLs from being injected? Perhaps you can use the same method as Firefox?

https://hacks.mozilla.org/2023/03/letting-users-block-injected-third-party-dlls-in-firefox/

 

That was the plan, but it turned out this is more complex. WFC has one developer, Mozilla has 700 people working on Firefox. For now, WFC version 6.23 has this feature disabled until I figure out a better solution.
