Spybot removes passwords

[avwood]

I am anxious to download the latest version of Spybot - 2.3. But I am concerned that when I use it, it will remove all my passwords as has happened previously. How do I set up 2.3 so that it does not remove my passwords when I scan? In answering me, please note I am elderly with limited computer knowledge so please an easy description.
I would be so grateful for your help. When you answer can you pleas send me an email to ... If I have to come back to the forums to find a reply, I may never be able to get back to the right spot. My computer knowledge is that bad.
Thank you so much for your help.
