TinyWall includes a combination of features that sets it apart from both commercial and freeware firewalls. TinyWall does not display popups that "urge users to allow". In fact, it will not notify you of any blocked action. Rather than displaying popups, TinyWall allows users to whitelist or unblock programs via various methods. For example, you can just initiate whitelisting by a hotkey, and then click on a window that you want to allow. Or, you can select an application from the list of running processes. (Of course, the traditional way of selecting an executable also works.) This approach avoids popups but still keeps the firewall very easy to use. It will also limit the list of unblocked programs to those that the user really needs, which is optimal from a security standpoint. TinyWall gives Windows Firewall a sane and secure configuration and presents you with a simple interface where you can easily define what has network access and what not, while preventing other programs from modifying or overwriting your firewall settings.

Features:
TinyWall does not annoy you with popups at all, yet it is still extremely easy to add exceptions to your firewall rules.
TinyWall actively blocks hundreds of trojans, viruses and worms.
TinyWall does not require you to know about ports, protocols and application details.
TinyWall prevents malicious programs from modifying the settings of Windows Firewall.
TinyWall does not install drivers or other kernel components, is free and lightweight.
