To "celebrate" this month's regularly-scheduled security patch release ("Patch Tuesday") Zone Alarm is giving away its Zone Alarm Pro Firewall software (normally $39.95). The offer is available today (October 13, until midnight ET) only and includes a one-year license to the software for use on up to three PCs. Head on over to the Zone Alarm web site for more info and the free download.
Thanks to David S. for the tip.
