Abstract: To provide validation information to web publishers indicative of the presence of operational malicious software protection systems on user computing devices, an evaluation system resident on a web publisher server can cause web content, including validation request data, to be transmitted from the publisher server to a computing device. A submission system resident on the computing device can analyze the web content for the validation request data, and can cause the validation information to be transmitted from the computing device to the evaluation system based on the analysis. Upon receiving the validation information, the evaluation system can analyze it to determine the likelihood that content delivered to the computing device will be viewed by a real user (and not by automated computer programs).

Abstract: Methods and systems for administering a browser store for computing device web browser applications, particularly browsers featuring tabbed viewing of web pages. A qualifying trigger event, such as a change in the current active tab of the browser, or a navigation to a URL in the active tab, is detected by an exemplary system. The system, having been monitoring user interaction with the browser's tabs, regulates the browser store such that, upon detecting a trigger event, only data (e.g., cookies) pertaining to the web site whose web page is presently displayed in the browser's active tab is retained. Any other data unrelated to the web site is copied to a virtual memory for future reference and purged from the browser store. Additionally, any data pertaining to the web site that may have been previously transferred to the virtual memory is retrieved therefrom and relocated to the browser store. Moreover, any such data retrieved from the virtual memory that require updating, e.g.
