Threat Details:

Categories:
  • hijacker
  • adware
  • bho

Description:
jZip.Toolbar gets installed in background without user consent during the installation of jZip, a 7Zip clone. jZip is supposed to be adware free. jZip.Toolbar displays advertising and adds itself to the Internet Explorer, Firefox and Opera. It also changes the start page and runs a so called Datamanager in background. This Datamanager is only associated with the toolbar and not with the jZip packer/unpacker.
