By detecting and preventing intrusions, ZoneAlarm Free Firewall keeps your PC free from viruses that slow down performance, and spyware that steals your personal information, passwords, and financial data. ZoneAlarm is a software firewall originally developed by Zone Labs.

The "trusted zone" generally includes the user's local area network and can share resources such as files and printers, while the "Internet zone" includes everything not in the trusted zone. The user can specify which "permissions" (trusted zone client, trusted zone server, Internet zone client, Internet zone server) to give to a program before it attempts to access the Internet (e.g. before running it for the first time) or, alternatively, ZoneAlarm will ask the user to give the program permission on its first access attempt.

You need a password for the Windows network logon, your e-mail account, your homepage's FTP password, online passwords (like website member account), etc. etc. etc. The list is endless. Also, you should use different passwords for each account. Because if you use only one password everywhere and someone gets this password you have a problem... A serious problem. The thief would have access to your e-mail account, homepage, etc. Unimaginable.

KeePass is a free open source password manager, which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key file. So you only have to remember one single master password or select the key file to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish). For more information, see the features page.

Is it really free?
Yes, KeePass is really free, and more than that: it is open source (OSI certified). You can have a look at its full source and check whether the encryption algorithms are implemented correctly.
