Within a double quoted string (like your txt) the backslash character
(\) sets up an escape sequence; so the trailing \" is interpreted as
an embedded quote mark. You need to use two backslashes to get the
effect that you're after, e.g.

    txt = "Messages posted to this group... on the Internet. \\"
    puts txt.gsub('\\', '')

For more info, see the "Strings" section of this chapter from Programming Ruby:

Hope this helps,
