Threat type:

Adware - Adware is a software application which displays advertisements on your computer. Advertisements can be displayed through pop-up / pop-under windows, additional bars or toolbars, underlined links or buttons that appear on a computer screen. Adware applications include additional code that delivers the ads. Adware authors earn money when users click on those ads. Occasionally, adware includes code that tracks user's site visits and passes it to third parties without the user's permission or knowledge.

BHO - A Browser Helper Object (BHO) is a software application that runs automatically whenever you start Internet Explorer. Browser Helper Objects are typically installed by other programs such as toolbar accessories and can track internet usage, create popup windows, display additional information on a viewed page and collect information that is transmitted by you over the internet. Malicious software that exploits this technology can replace banner advertisements with other ads, monitor your actions, change your home page, etc.

Backdoor - A Backdoor is an undocumented or secret means that can be used to obtain unauthorized access to your computer, or a malicious program that uses such a means to penetrate a computer system. Backdoor applications exploit vulnerabilities of installed programs or operating system and allow attackers to gain control over your computer system. Backdoor works in the background and hides from the user. It is always a high security risk.

Hijacker - A Hijacker is a software application that takes control of your browser's settings. Usually it changes your home page and redirects it to some unknown site or modifies your search settings. It prevents you from changing back your browser's settings. An infected browser usually operates much slower.

Toolbar - A Toolbar is a group of buttons that performs different tasks. Unwanted toolbars are usually installed by adware programs that try to send users to their paying advertisers.
