PUP.Optional.Conduit refers to an online platform that allowed Web publishers to create custom toolbars and apps at no cost. Conduit toolbars may change user and/or browser settings, display advertising leading to other known PUPs, and cause the overall speed of the computer to diminish.
Conduit was demerged to Israeli-based Perion, and the company ceased toolbar operations in 2014.
Conduit was more of the widely encountered toolbars of the time.
While the impact of this PUP has diminished with the dissolution of the Conduit brand, detections may remain on legacy systems.
