Abstract: A method for limiting access to resources of a personal computer with an operating system while allowing access to information via a web browser program. The method includes running on the personal computer a locking program that modifies functions of the web browser program and functions of the operating system to disable functions that allow access to any data file in a memory of the computer other than web browser access to a specified list of URL's until an authenticating input is received by the computer. The method may further include launching the web browser program if it is not already launched. The method may further include a delay from the running of the locking program until it disables functions of the operating system and the web browser program such that disabling is commenced upon expiration of a set amount of time without keyboard or mouse input activity.
