Installing Free BSD 5.21

[Chris Winkler]

I have had a crash on my computer I try to install McAfee Internet Security 6.0 I keep getting this error message. The Wizard was
interrupted before 6.o could be completely installed. It say new program when I check McAfee it says it is empty. Will installing this 
help this  problem. I don't know much about computers but I am trying to follow all the directions from McAfee support but there instructions are just not working.
Kind Regards Chris
