I learned this song from my Great-Grandfather and my Grandfather as I was growing up. I never knew it was actually a song. I thought they made it up. All of my family is from the Ozark Mountain/Northwestern Arkansas region. So yes, I would be considered a Hillbilly. Here is a wikipedia article about the song.
“First found on March 26, 1999, Melissa shut down Internet mail systems that got clogged with infected e-mails propagating from the worm.
Melissa was first distributed in the Usenet discussion group alt.sex. The virus was inside a file called “List.DOC,” which contained passwords that allow access into 80 pornographic websites. The worm’s original form was sent via e-mail to many people.
Melissa was written by David L. Smith in Aberdeen Township, New Jersey, and named after a lap dancer he encountered in Florida.”
