Laptop data encryption program

[grow14me2]

I got ZoneAlarm’s free firewall in addition to my antivirus software, and it seems like my laptop is fairly secure from malware.

I am now more concerned about losing my laptop, and anyone being able to get all my data off the drive.

Zonealarm now make this Datalock laptop data encryption program:

It prevents people from booting, and it encrypts the data.

My question, is that can this encryption be broken and people then getting access to the data?

It is easy to decode this encryption?
