    A browser hijacker using a BHO to display ads.

    The division into "families" was done by Andrew Clover of Doxdesk.

    Finding all of them was a group effort here at Wilders, at GSF and at Spyware Warrior.

    The listing is displayed like this: "variant" - "first discovered" - "filename"
    "CLSID" - "Name of the BHO"
