I am long time user of Avast! Free with Windows Firewall or Outpost Firewall PRO.
About two months ago, I tested quite a few Firewall Programs including Avast! Internet Security on my two laptops. In the end, I had to reformat both my two laptops as I couldn't access anyone on my home network, including the NAS Server.
Hi aladdin and welcome: This sounds like a real mess up!
You stated you "tested quite a few Firewall Program" and they are the hardest to rid your sytem of reminents left behind long after we think we uninstall the Firewall properly.Back in the day it took me and some tech friends of mine 2months to TOTALLY get rid of ZoneAlarm..that software litterally took over my system
I don't know if my experience will help...so take it with a grain of salt.
Here is what I have done with great success;
I pet peave (hobby) of mine is seeking out and testing all kinds of Security Software and mostly interested in Anti-Virus and especially a"Firewalls" I have found over the years it is absolutely essential that when uninstalling a Firewall that first you download the VENDERS Uninstall/Clean up Utility for that specific piece of softward (In your case a different Uninsall tool from each vender that sells/supports that particular Firewall.
Many Firewalls are EXTREMELY hard to get rid of left over reminent (Registry Keys and Drivers especially).
So for every Firewall installed you should first remove with the product UNinstall option in it Start/Programs/Product Folder....If the product doesn't come with an Unistaller option, you then uninstall from Add and Remove Section.
You then need to run each Uninstall/Clean up Utility in safe mode supplied by the vender (which you should already have located and downloaded to Special file related to the product in represents (for easy access when needed)
THis process should be followed(or should have been) for every Firewall you had installed on your sytem at any time.
After that time consuming process is completed , You are not done yet.
Noe go to C:/WINDOWS/Temp folder and delete everything in that folder. [ Mske sure you have "show hidden folders" ticked in the Windows Explorer Tools Section under Folder Options]
Then go to Documents and Settings/User(YOUR ACCOUNT)/Local Settings/Temp and delete everything in that folder.
There 1s an amazing amount of file data and settings that are left behind in these folders, even with the Uninstll tools being used
Now you are getting closer to being finished
Run a Registry Cleaner that you trust ( I use JV16 Power Tools 2010..60 day free trial) and a Disk Defrag. Now reboot and Install the product you want to use.
This process has worked for me everytime I could not get a Firewall to function properly
Try everything else you feel might work first
NOTE: THis should be looked at as a last resort due to the time involved (around an hour or more)
Good luck if you cannot succeed in any other way and choose to go this route.
Let me Know either way.
