What is PDF Reader Toolbar?

Installs a Conduit toolbar in your Web browser that collects and stores information about your web browsing habits and sends this information to Conduit so they can suggest services or provide ads via the toolbar. The toolbar is typically bundled with the free 4shared program as an option during installation and does not necessarily get uninstalled when the 4shared is removed from the user's PC and must be removed manually. If the home page and search settings were modified by this toolbar, they need to be manually reverted back by the user.


The most common release is, with over 98% of all installations currently using this version. The program adds a toolbar to Microsoft Internet Explorer. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The primary executable is named tbPDF_.dll. A majority of users end up uninstalling this less than a week of it being installed. It also bundles additional software in the form of the Conduit Engine, which installs a potentially unwanted toolbar, and makes homepage and default search engine changes to a user's web browser. The setup package generally installs about 12 files and is usually about 4.8 MB (5,028,849 bytes).
