Query: I have to do what???

I had the free download of the zonealarm firewall and loved it. I had a different brand antivirus on my computer and when it expired I thought why not get zonealarm with their anti virus. Well it would not let me install it. After e-mailing for help I received a whole page of items that I have to go into my computer and remove registry entries,internet log folders, and the list goes on and on. I am shocked and afraid that I may crash or mess my computer up so I still have not installed it.
