## Background
BACKGROUND
This application relates generally to the field of malware or virus detection in personal computers. More specifically, the disclosure provided herein relates to providing feedback upon the detection of an invasion of a computer from a malware program.
Malware is a software program designed to invade or damage a computer system without the user's consent. Malware may include computer viruses, trojan horses, worms, rootkits, spyware, adware, and any other software that unexpectedly or without authorization invades a user's computer. Traditional malware protection software concentrates on the prevention of malware invasions by detecting the presence of a malware program and removing the threat or warning the user before invasion of the computer can take place.
When a traditional malware protection system warns a user of a potential infection, the warning may often be obscure or contain technical terms and jargon unfamiliar to a layperson user. In addition, if the traditional malware protection system detects and removes a threat before invasion, it also removes any user training effect in that the user does not learn the potential consequences of certain actions the user has performed. Further, because the tricks and mechanisms for delivering a malware program to a computer are constantly changing and evolving, the detection of malware programs is complex and may yield erroneous results.

DETAILED DESCRIPTION
The following detailed description is directed to methods, systems, and computer-readable media for providing contextual, audible feedback to a user of a computer system upon detection of an invasion of the computer system. Utilizing the technologies described herein, a contextually appropriate alert tone is played for the user immediately upon the detection of an invasion of the computer system. An alert tone is selected that inherently provides natural feedback to the user indicating the type and severity of the invasion without requiring the user to understand complex computer jargon or terminology. In addition, the immediate alert allows the user to be informed of the invasion in close temporal proximity to the user's actions that may have caused or facilitated the invasion, thus providing training for the user regarding the consequences of the user's actions.
In the following detailed description, references are made to the accompanying drawings that form a part hereof, and that show by way of illustration specific embodiments or examples. In referring to the drawings, it is to be understood that like numerals represent like elements through the several figures, and that not all components described and illustrated with reference to the figures are required for all embodiments.
Referring now to FIG. 1, an illustrative operating environment 100 and several software components for providing a contextual, audible alert of an invasion of a computer system are shown, according to embodiments. The environment 100 includes a computer 102, which may be any type of computer device, including, but not limited to, a desktop computer, a laptop, a notebook, an ultra-mobile personal computer (PC), a pocket PC, a personal digital assistant, or a smartphone. A user 104 may interact with the computer 102 through a user-interface (UI) device, such as a computer terminal 106. It will be appreciated that any number of UI devices may be imagined, including, but not limited to, a mouse, a keyboard, a display, a trackball, a keypad, a stylus, or a touch-screen monitor.
The user 104 may use the computer 102 to execute application programs 108 that perform a number of functions, such as word processing, editing spreadsheets, reading email, and Web browsing. The application programs 108 may depend on system files 110, data files 112, and configuration settings 114 stored on the computer 102 in order to perform the desired functions. The system files 110 may consist of shared libraries, such as dynamic link library (DLL) files or component object model (COM) components, that provide UI, network, file access, and other services to the application programs 108. The data files 112 may include files that contain data specific to one of the application programs 108, such as a document file used by a word processing application program. In some cases, the data files 112 may contain executable modules as well, such as a spreadsheet file that contains macro code.
The configuration settings 114 provide the necessary information for the computer hardware, the operating system, and the application programs 108 on the computer 102 to operate, and may include user preference settings that control how these components behave. For example, the configuration settings 114 may include a list of software programs that are to be loaded when the computer 102 is started, the location and services provided by the various system files 110, and associations between types of the data files 112 and the corresponding application programs 108. The configuration settings 114 may be stored in a central location, such as the registry database in a computer, such as the computer 102, running the WINDOWS® operating system from MICROSOFT CORPORATION, in individual configuration files located throughout the computer 102, or some combination of the two.
According to embodiments, a malware program 116 may also execute on the computer 102. As described above, the malware program 116 is a program that invades or infects a computer, such as the computer 102, unexpectedly or without authorization from the user 104. The malware program 116 may be executing as the result of an action taken by the user 104 of the computer 102. For example, the user 104 may have opened an attachment to an e-mail received on the computer 102, may have opened a spreadsheet file containing a macro program, or may have clicked a link on a webpage being viewed in a Web browser application executing on the computer 102.
The intention of the malware program 116 may be to damage the computer 102 in some way, by erasing the data files 112 on the computer 102, for example; to collect private information from the computer, such as email addresses, bank account numbers, websites visited, etc.; or to cause the computer to serve as a platform for forwarding spam e-mail or launching denial-of-service attacks. Types of malware programs 116 include, but are not limited to, computer viruses, trojan horses, worms, rootkits, spyware, and adware.
The malware program 116 may invade and infect the computer 102 by making modifications to the system files 110, data files 112, or configuration settings 114, in order for the malware program to perform its intended function. For example, the malware program 116 may add itself to the list of programs to execute when the computer 102 is started in the configuration settings 114, replace an oft used DLL in the system files 110 with a copy containing the necessary instructions to load the malware program, or place a macro or other executable code in the data files 112 that causes the malware program to execute whenever one of the data files is loaded by the associated application program 108. It will be appreciated by one skilled in the art that many other forms of malware programs and invasions of a computer system may be imagined, and it is intended that all such forms be within the scope of the present invention.
In one embodiment, the computer 102 also includes an invasion detector program 118 responsible for detecting the invasion of the computer 102 by the malware program 116. The invasion detector program 118 may be loaded by the computer 102 upon startup and may run in the background and continuously monitor the system files 110, data files 112, configuration settings 114, and other components of the computer to detect changes that indicate an invasion of the computer 102 by a malware program, such as the malware program 116. As will be described below in more detail in regard to FIG. 2, when the invasion detector program 118 detects an invasion of the computer 102, the invasion detector program selects an appropriate alert tone from a set of alert tones 120 available on the computer 102 to play to the user 104, according to exemplary embodiments. The alert tone 120 is played through a speaker 122 connected to the computer 102. In addition, the invasion detector program 118 may log the details of the invasion to a diagnostic log file 124.
According to one embodiment, the alert tones 120 consist of a group of digital recordings or approximations of natural utterances that are contextually related to a particular type or severity of invasion of a computer. For example, one alert tone 120 may be a recording of a painful groan that would be played when an invasion of the computer 102 resulted in execution of a malware program, such as the malware program 116, which caused damage to the system files 110 or data files 112 on the computer. Playing the groan to the user 104 upon the invasion of the computer 102 clearly indicates to the user that the computer had been infected and that serious damage has resulted.
Another alert tone 120 may consist of a recording of a person saying “Oops!” This alert tone 120 may be played when an invasion of the computer 102 is detected that is not as severe, for example, upon the download of a tracking cookie by a Web browser application. By providing natural sounding alerts that are contextually related to the severity and type of invasion, the user 104 can be provided an immediate notification of the context of the invasion that has taken place, without having to have an understanding of computer terms or jargon in order to understand the complex messages displayed by traditional malware protection systems.
It will be appreciated that other types of sounds contextually related to the type and severity of an invasion may be played to the user 104, beyond the natural utterances described above. In a non-limiting example, an air-raid siren may be played to the user 104 upon detection of an invasion by a trojan horse program. It will further be appreciated that other forms of contextual alerts may be provided beyond the aural alert tones described herein. For example, upon invasion of the computer 102 by a malware program, such as the malware program 116, which destroys the system files 110 and data files 112, the computer may emit fake smoke or an odor approximating the smell of an electrical short, providing immediate feedback to the user 104 that the computer has been severely damaged.
In one embodiment, the alert tones 120 may be provided with the computer 102, such as when installed as part of the configuration by the computer manufacturer. This allows for support personnel to understand the meaning of each alert tone when diagnosing a computer problem. For instance, following the example provided above, if the user 104 contacts support personnel for the computer 102 and complains that “My computer says ‘Oops’ every time I visit this website,” the support personnel will immediately know that the website is placing unauthorized cookies on the computer.
In another embodiment, the user 104 may provide the alert tones 120. The user provided alert tones 120 may be a set of digital recordings purchased and/or downloaded from the Internet, similar to ringtones for cell phone devices, or the alert tones may be recorded by the user 104 in his or her own voice, or the voices of family members or friends. For example, the user 104 may record a set of the alert tones 120 consisting of the user's spouse chastising the user by name at different levels of severity, to be matched contextually with various levels of severity of potential invasions of the computer 102.
Referring now to FIG. 2, additional aspects regarding the operation of the components and software modules described above in regard to FIG. 1 will be provided. It should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as operations, structural devices, acts, or modules. These operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof.
It should also be appreciated that, while the operations are depicted in FIG. 2 as occurring in a sequence, various operations described herein may be performed by different components or modules at different times. In addition, more or fewer operations may be performed than shown, and the operations may be performed in a different order than illustrated in FIG. 2.
FIG. 2 illustrates an exemplary routine 200 for providing contextual, audible feedback to a user, such as the user 104, upon detection of an invasion of a computer system, such as the computer 102, in accordance with embodiments. The routine 200 begins at operation 202, where the invasion detector program 118 detects an unexpected and/or unauthorized event or events indicating an invasion of the computer 102 by a malware program, such as the malware program 116. As described above, the detected event may be a change in one or more of the system files 110, data files 112, configuration settings 114, or other components of the computer 102.
For example, the invasion detector program 118 may detect that the malware program 116 has added itself to the list of programs in the configuration settings 114 to execute when the computer 102 is started, or has replaced a system DLL in the system files 110 with a copy containing malicious code. It will be appreciated that many additional methods known in the art may be utilized by the invasion detector program 118 to detect an invasion of the computer, including, but not limited to, detection of a process running at an unexpected security level, detection of the loading of an un-signed executable or shared library file, or detection of a UI window being opened at coordinates outside of the visible area of the display.
Upon detection of the invasion of the computer 102, the routine 200 proceeds from operation 202 to operation 204, where the invasion detector program 118 selects the appropriate alert tone from the alert tones 120 to play to the user 104 in response to the invasion. As discussed above, the appropriate alert tone 120 is selected based upon the context of the invasion, according to embodiments. The context may include the type of the invasion as well as the severity of the consequences. The invasion detector program 118 may select a natural utterance that symbolizes pain, such as a groan, grunt, or “Ugh” as appropriate feedback for a type of invasion that causes damage to the computer 102. Similarly, the invasion detector program 118 may select a natural utterance that reflects concern, such as “Uh-oh” or “Look out!” for a type of invasion that collects private information.
In addition, the invasion detector program 118 may consider the severity of the invasion in selecting the appropriate alert tone 120. For an invasion that results in the collection of personal information to be sent to a remote computer over the Internet, the invasion detector program 118 may select an alert tone that relates the severe privacy ramifications to the user 104, while an invasion that simply places a tracking cookie in a web browser program cache may result in more passive feedback, such as a sigh or “Oops!”
In a further embodiment, the invasion detector program 118 selects the appropriate alert tone 120 based upon user preferences on the computer 102 as well. Different user preference settings may be available for different users in the configuration settings 114 of the computer 102. A particular user 104 of the computer 102 may have downloaded or recorded a unique set of alert tones 120 from which the invasion detector program 118 is to select the appropriate alert tone. In addition, different sets of alert tones 120 may be provided with the computer 102 that are appropriate for different classes of users. For example, the invasion detector program 118 may select an alert tone of “Oh my!” in response to a particular type of invasion for an older generation user 104, but may select “Dude!” for the same type of invasion for a teenage user. It will be appreciated that the selection of the appropriate alert tone to utilize as feedback may also be based on other characteristics of users, including, but not limited to, level of knowledge, native language, age, or cultural experience.
From operation 204, the routine 200 proceeds to operation 206, where the invasion detector program 118 plays the selected alert tone 120 to the user 104 through the speaker 122 connected to the computer 102. According to one embodiment, the invasion detector program 118 plays the selected alert tone 120 immediately upon detection of the invasion so that the alert tone indicating the invasion is heard by the user 104 within close temporal proximity to the user's action that may have caused or facilitated the invasion. In this way, the contextual, audible feedback has a “training effect,” in that the user 104 may learn the types of actions that may cause an invasion of the computer 102 as well as the potential consequences of similar such actions.
The routine 200 then proceeds from operation 206 to operation 208, where the invasion detector program 118 logs detailed information about the invasion to the diagnostic log file 124. This information may include the time and date that the invasion was detected, the event or events detected that indicated the invasion, and any other data that will aid support personnel in repairing the computer 102. From operation 208, the routine 200 ends.
