Need helpmwith BackWeb Lite

I used the Spybot program and must have repaired too much stuff. I get error messages on not being able to find some of the BackWeb program. What does BackWeb Lite actually do and can it be restored to normal on my XP?

Is BackWeb Lite a necessary program and can it be removed?

 

I'm SUCH a lazy typist.
Does this explain it?

*edit*
One more link.

 

Privacy Bird

This little program doesn't "do" anything, such as removing or neutralizing spyware, but it gives the stated privacy policy of any site with one click. It also warns (if you ask it to) about any form or site that does not meet the privacy criteria YOU specify. I've been running it for months, and have enjoyed the education. Not all you see is what you get, and I'm not paranoid, just experienced! LOL! Check it out: www.privacybird.com (an AT&T beta)
