What is Chatzum?
Chatzum toolbar is a browser add-on, which enhances Facebook's photo viewing experience - it magnifies photos when hovering over them. While this function can be useful for social network users, Chatzum is categorized as an unwanted program, due to its deceptive methods of installation and also for not providing a full uninstall facility. By default, when installed on your computer, Chatzum toolbar automatically changes your browser's homepage to search.chatzum.com
The search engine presented within this new homepage is powered by Google search, with slight modifications, making sponsored results difficult to distinguish from organic ones. Furthermore, if you decide to remove Chatzum toolbar, it is necessary to take several manual steps before this toolbar is removed from all of your Internet browsers. The uninstall process via your operating system control panel will not revert your browser settings to the default - your homepage will remain set at search.chatzum.com and your browsers will retain this toolbar. Chatzum toolbar is not a virus, but rather, a toolbar employing a deceptive strategy to prevent computer users from fully uninstalling it using Control Panel. If you have not willingly installed this toolbar, or did so inadvertently, remove it from your computer immediately.
Chatzum toolbar can be downloaded from its homepage or through software distribution websites. This toolbar can also come as part of a bundle of free downloadable sofware. To avoid installing Chatzum toolbar, or other similar unwanted toolbars inadvertently, always carefully study the installation windows for software (especially free software) that you have downloaded from the Internet. If you install your software recklessly (by just clicking 'next' in the installation process), your Internet browsers can easily be crowded with unwanted toolbars such as Chatzum.
