I just needed to recover my dial-up acoount password and when I've done it with a program ( Cain ) I saw a strange line in addition to recovered accounts which was like this :
" crypt_My computer name here Pwd: qPpS "

I never had such a password on my pc. I don't know what it is and at least it is related to which program.
Has anyone any idea?

This was happened on win98 machine with zonealarm installed and updated Norton AV and the cleaner.
