Today the most common thing for a hacker is to steal your passwords on various applications such as FireFox, MSN, XFire etc. Antiviruses doesn't work always, as hackers crypt their stealers with undetectable crypters and antiviruses don't detect them. So instead antivirus we are going to use firewall !

How password stealers work ?
They bind stealers into keygens or applications and once the application is executed, the stealer is also executed in hidden mode. Then the stealer finds it's target like the folder where all firefox passwords are stored, then decrypts the passwords and sends them to the attacker's FTP.

Example of a log by password stealer:-


what we need is:-
As i said above we need a good firewall. One of the best firewall is Comodo. By the way you can use Windows Firewall with Advanced Security by Microsoft, but this only works in Windows Vista or Windows 7.

How to Configure:-
1. Comodo Internet Security:-
After you install it, reboot your PC. Now set the Firewall Security Level to Custom Policy Mode (as shown in the image).


After you've done that, you must create application rules in order to access the internet. To do that, open up Comodo and go to: Firewall -> Define a New Trusted Application. Now make rules for your applications that need internet access.


2. Windows Firewall with Advanced Security
This only works in Windows Vista and Windows 7 !!!

Now go to start and type: wf.msc
After opening it, you must block all outbound connection. To do that open up Windows Firewall with Advanced Security and click properties.


Now make sure that the 3 sections outbound connection is set to Blocked.


After that you need to create application rules in order to access internet.To do that, go to Outbound Rules and make new rule as shown on the image.



And Thats it,ur safe !!!
