Why the Crawler Toolbar is Unwanted
Some Internet users have asked themselves how to remove the Crawler Search from web browser because they did not expect to have the Crawler toolbar for IE and Firefox after installing another program. This is because some software installers are bundled with the Crawler toolbar that additionally modifies the search and home pages of web browsers. Examples are the setup files of Spyware Terminator and IMTool Pack which are bundled with the Crawler toolbar because the said programs are also owned by Crawler, LLC.
There is an option to opt out of installing the Crawler toolbar but the problem is there is no option to cancel or modify the installation preferences once the computer user mistakenly clicked on the "Next" button. Another issue is when you unchecked the option to make Crawler.com as search provider, the installer continues to add it in the search provider list in IE and FF, in addition to making it as default search engine. This type of installation method is unacceptable since the developer of the software is obviously pushing the installation of the toolbar and search provider. The end-user cannot even click on the "X" option to cancel the installation and as you can see in the above screenshot. There is no option to go back to the previous installation options either.
Some people also dislike the long list of sponsor ads when using Crawler Search before they can view the actual search results:
Privacy conscious users are not comfortable that the Crawler Search is connecting the search actions to a third-party company, an advertising network without the end-users' consent:
Note that the Crawler toolbar in Spyware Terminator program includes a Web Security Guard feature that provides anti-phishing protection. The toolbar that is bundled in IMTool Pack and the standalone Crawler toolbar installer does not include Web Security Guard. The end-user license agreement (EULA) of the Crawler toolbar installer only mentions that logs of websites that you visits and computer user information is sent to Crawler servers if Web Security Guard is installed, but it mentions nowhere that the program will send search actions to a third-party company * if only the toolbar exists on the computer (without the Web Security toolbar).
* pbid.pro-market.net is an advertising network that Crawler Search communicates with when using their toolbar. The above Fiddler screenshot clearly shows that a sample search action is not only sent to Crawler server but also to pbid.pro-market.net.
