Back Web - Do I Need It?

A question for all you computer people out there - what exactly is Back Web on my computer?

Is it something that was part of the original installation, or is it a Gator-type thing that has snuck itself on to my hard drive?

What does it do, and (assuming it is not meant to be there) is it okay to delete it?

I am running Windows Me on a Pentium III PC. Let me know if you need more info.

Thanks.
