Dragan on Security

ITSecurity has published great and useful list of 103 free security apps for Mac, Windows, and Linux. This list is divided to groups for Antyspyware, Antivirus, Rootkit, Web utility, Intrusion Detection System (IDS), Virtual Private Network (VPN), Temporary files, Wireless, and Encryption.

In my opinion, this list can be much better, but it is still useful.

List is here.
