Drive-By Download Tutorial

A drive-by download is a program that is automatically downloaded to your computer without your consent or even your knowledge. Unlike a pop-up download, which asks for assent (albeit in a calculated manner likely to lead to a "yes"), a drive-by download can be initiated by simply visiting a Web site or viewing an HTML e-mail message. If your computer's security settings are lax, it may be possible for drive-by downloads to occur without any further action on your part.

Frequently, a drive-by download is installed along with a user-requested application. (In this case, the unwanted application is sometimes called a barnacle.) For example, a file sharing program might be included with a spyware program that tracks and reports user information for targeted marketing purposes. An associated adware program can then generate pop-up advertisements using that information.
