Having had the misfortune of trying to "Fix" my mother-in-laws laptops over the years I can also attest to these things still getting packaged in with certain programs.
She usually has a few of them on her browser whenever I take a look at it.
Not sure if its older programs she downloads (She quite likes point and click puzzle games) or just her being of that generation of seeing a pop-up and just taking it at face value and installing whatever its telling her to install.
