Another good security advise (recommended by most security experts):

Do you know another FREE firewall software for Windows? Please let us know about it. If we choose to take it into our TOP FREE FIREWALLS list you will receive a FREE single user license of an iOpus utility of your choice (or your money back if you are are already a registered user). 

Here is a list of free firewalls that were suggested to us lately and that are queued for testing:

• Lock n' Stop (Lite version is free)
• Premedius
• BitDefender (Firewall/Antivirus)
• Jetico Personal Firewall
• R-Firewall
• Securepoint Personal Firewall & VPN Client
• SoftPerfect Personal Firewall
• AVG firewall
  

Want to suggest a service? Please let us know here.

And here is a list of free firewalls that we tested recently already and rejected them, i. e. they did not make it into the "iOpus' TOP 5 List of free firewalls. Please note that these rejected services might still be good and useful. They simply did not make it into our "TOP 5" list, i. e. they are - according to our opinion and tests - not better than any of the 5 free firewalls in the IOPUS's TOP 5 list.

• http://www.tinysoftware.com - no longer available
• Sygate Personal Firewall has been acquired by Symantec and the firewall software will be discontinued.
• Kerio Personal Firewall was acquired by Sunbelt Software. The software is now available at http://www.sunbelt-software.com

Note: Windows XP already contains a mediocre firewall. This firewall is NO replacement for a dedicated software solution. 

Important: Are you connecting to the Internet via public hotspots? Then you need a VPN solution (e. g. the free iPig VPN software ) in addition to a good firewall.
