What is ForceField? Recently installed and SP3 on my XP Home.

In "My Documents" it lists "Forcefield Shared Files" and it is empty.

My only browser is IE. Is ForceField something I need?

I have checked this forum, but couldn't come up with an answer.

Off the subject, but can I delete the ZA set-up icon on my desktop? The ZASS seems to be working fine.
