Do try and find other user's comments about free programs before going too far. We got badly caught with one - very easy to use - lots of matches etc, but NO security.
Cost us lots of $$$ to get the laptop cleaned up! 98 viruses and bugs had screwed everything up despite firewalls etc. When the feedback site was checked - after - there were bad comments!
Don't know if I can name the dud on here. We bought Family Tree Maker ( Ancestry.com ) which is Ok - also hear good reports of Legacy from a very experienced user.
Good luck. T
