Qtvglped Toolbar is a variant of the infamous Zlob Toolbar, just like so many before it (such as, Egodktf Toolbar, Emlkdvo Toolbar and others). Qtvglped Toolbar is typically spread by disguising it as a Video Access Codec. It’s functions are the same as the other clones’: it has four buttons, all of which redirect to rogue anti-spyware websites. Qtvglped Toolbar displays popups and fake system notifications to "inform" you of a non-existent infection. The primary goal of Qtvglped Toolbar is to promote rogue anti-spyware programs. None of the programs and services Qtvglped Toolbar might promote are to be trusted and the toolbar itself should be removed upon detection.
