Notice that the same font is used in the header as is used throughout the paper, there is no comma or other mark of punctuation after the heading, and there is a single space between the name and the page number.
Part of the Malware glossary: An IFrame (Inline Frame) is an HTML document embedded inside another HTML document on a website. The IFrame HTML element is often used to insert content from another source, such as an advertisement, into a Web page. Although an IFrame behaves like an inline image, it can be configured with its own scrollbar independent of the surrounding page's scrollbar.
With iFrame, content is kept in its native recorded format, so importing and editing video is fast, and file sizes are small. iFrame is based on industry standards, such as H.264, AAC, MP4, and QuickTime, so it can be used with compatible Mac, iOS, and PC applications.
