If you're a fan of ZoneAlarm or just hunting for a featured software firewall, you may be interested in a promotion Check Point Software is running today. The company is offering a free one-year license for its ZoneAlarm Pro Firewall 2010, which usually costs about $40. If this sounds a bit familiar, it's probably because the same promotion was available this time last year.

ZoneAlarm has been extremely popular over the years, and while it caused Vista users plenty of grief, the latest version claims compatibility with Windows 2000 through Windows 7. If you're at all interested, be sure to hop on the giveaway as soon as possible, because it's a one-day deal. The company notes that the offer is only valid for new customers, and the license can be used on up to three PCs until October 14 2010.

If you miss the cutoff and still want to give ZoneAlarm a shot, you can always grab the free edition from our downloads section.
