Security firm AVG is doubling down on cloud storage.

The company today announced LiveKive, a service that allows people to upload data to the cloud that can then be downloaded to other computers or Android- and iOS-based devices with the LiveKive mobile app. It works on both Windows and Mac.

AVG is currently offering two packages: a $49.99 per year option that gives customers 25GB of online storage and a $79.99 a year plan with unlimited data. In either case, people can upload files, folder, and multimedia content. The service also supports automatic syncing for those who don't want to manually choose what should and should not be saved in the cloud.

At first glance, AVG's LiveKive closely resembles Dropbox and Box.net. Both of those services allow people to sync content with the cloud and share files on other products, including mobile devices.

Dropbox offers 2GB of backup for free and charges $10 per month and $20 per month for 50GB and 100GB, respectively. Box.net offers up to 5GB of storage at no cost to its "personal" users, but charges $15 per user per month for 500GB of Web storage.
