Delta Search Toolbar

Delta Search Toolbar Description

ScreenshotThe Delta Search Toolbar is a browser plug-in. ESG security researchers have received various reports claiming that the Delta Search Toolbar exhibits unwanted behaviors, more commonly associated with malware. However, it is important to note that the Delta Search Toolbar is not malicious; rather, this browser extension is often classified as a PUP, or potentially unwanted program. Delta Search Toolbar is developed by Conduit Ltd, a software developer and distributor responsible for a number of other browser toolbars, such as the Eazel Toolbar and the Iminent Community Toolbar.

The Delta Search Toolbar can affect various browsers, including Internet Explorer, Mozilla Firefox and Google Chrome. The Delta Search Toolbar is associated with the Delta Search search engine, meaning that it will make changes to your browser that force you to visit that search engine against your will. For example, ESG security researchers have observed that the Delta Search Toolbar changes your homepage to Search.conduit.com. This is a common complain that has been leveled against most browser extensions developed and distributed by Conduit Ltd. Delta Search Toolbar has several intrusive behaviors, such as causing browser redirects and may affect your browsing and online security.

How the Delta Search Toolbar Enters a Computer

Unlike malicious programs, the Delta Search Toolbar requires the permission of the computer user to be installed. However, it is possible to install Delta Search Toolbar unwittingly when installing another program. Another important thing that needs to be noted is that the Delta Search Toolbar's installer includes a check box that allow the computer user to install only certain features. Because of this, the Delta Search Toolbar's most annoying features, such as changing the affected browser's homepage or default search engine, are only activated after prompting the computer user. Installing the Delta Search Toolbar occurs unwittingly after installing a freeware program that has been bundled with the Delta Search Toolbar. This is often done by freeware developers or distributors as a way of monetizing their freeware programs.

The Delta Search Toolbar and TuneUp Utilities 2013

One of the main reasons why many computer users have complained about the Delta Search Toolbar is that it comes bundled with a program named TuneUp Utilities 2013. This program is not dangerous, but can be frustrating because it may consume system resources and spam the computer user with messages. TuneUp Utilities 2013 is often included with other Conduit toolbars.
