How do I completely uninstall Snap Toolbar?

A friend, who doesn’t know anything about computers yet, has gotten infected with the Snap Toolbar. The only thing I can find so far about how to get it off is a “Remove Snap Toolbar” exe file published by www.securitystronghold.com – BUT I worry about telling her to download this as Web Of Trust has graded this site as RED. Has anybody else used this tool & is it safe, despite the site reputation? Thanks, Dax
