Delta-Search.com Redirect

Also Known As: Delta-Search.com browser hijacker
Damage level: Moderate

What is Delta-Search.com?

The Delta-Search.com website is promoted using browser toolbars (Delta toolbar and Babylon toolbar). Although this website seems legitimate and is not related to malware or virus infections, computer users commonly visit this site unwillingly via enforced redirection.

These redirect issues are caused by Delta toolbar - when users install the toolbar on Internet Explorer, Google Chrome, and Mozilla Firefox, their browsers are modified by the homepage and default search engine setting being assigned to delta-search.com

delta-search.com browser hijacker

The website and Delta toolbar are closely related to Babylon toolbar adware. Many computer users install the Delta toolbar inadvertently without their consent when installing Babylon (if users choose not to change their default search engine and homepage to search.babylon.com, they are tricked into installing Delta toolbar during the next step).

Other known distribution channels of Delta toolbar are download websites (such as softonic.com, filewin.com, download.com, etc.) that 'bundle' the toolbar via 'download clients'. In this scenario, users are forced to download the toolbar if they wish to use the site to download free software.

Delta-Search.com and Delta toolbar are categorized as adware, and therefore, you are strongly advised to eliminate this browser add-on from your computer.

Delta toolbar causes browser redirects to delta-search.com and, commonly, this toolbar is installed without users' consent by third party freeware or free browser extensions. This browser hijacker is similar to searchgol and buenosearch amongst many others.

Note that a common tactic, widely used by free software developers, is to 'bundle' unwanted toolbars with their programs to monetize their products. Thus, to prevent installation of such adware on your Internet browsers, closely inspect each freeware installation step, disallowing any suggested changes to your Internet browsers and avoid installation of additional software.

If your download is managed by a download client, decline installation of promoted browser add-ons. When installing free software, ensure that you choose the 'Advanced' or 'Custom' installation options - this will reveal any hidden (bundled) software that you may choose to deselect.

To eliminate browser redirects to delta-search.com, and to uninstall Delta toolbar, use the removal instructions provided.
