A code that you receive when purchasing a license for Kaspersky Free. This code is required for activation of the application.
The activation code is a unique sequence of twenty alphanumeric characters in the format xxxxx-xxxxx-xxxxx-xxxxx.
Databases that contain information about computer security threats known to Kaspersky Lab as of when the anti-virus databases are released. Entries in anti-virus databases allow detecting malicious code in scanned objects. Anti-virus databases are created by Kaspersky Lab specialists and updated hourly.
Files included in the Kaspersky Lab installation package that are responsible for performing the main tasks of the corresponding application. A particular application module corresponds to each type of task performed by the application (protection, scan, updates of databases and application modules).
Denying access to an object from third-party applications. A blocked object cannot be read, executed, modified, or deleted.
An activation code for Kaspersky Free provided to the user in exchange for bonus points.
Bonus points are points that Kaspersky Lab awards to users who participate in the Protect a Friend program. Bonus points are provided to the user if the user publishes a link to a Kaspersky Lab application on social networks or pastes the link in an email message, and the user's friend then downloads the application installation package via this link and activates the application.
An archive file that contains a decompression program and instructions for the operating system for executing it.
A list of web addresses whose content may be considered to be dangerous. Created by Kaspersky Lab specialists, the list is regularly updated and is included in the Kaspersky Lab application package.
List of web addresses which have been defined as phishing web addresses by Kaspersky Lab specialists. The databases are regularly updated and are part of the Kaspersky Lab application package.
A boot sector is a special area on a computer's hard drive, floppy disk, or other data storage device. It contains information on the disk's file system and a boot loader program, which is responsible for starting the operating system.
There exist a number of viruses that infect boot sectors, which are thus called boot viruses. The Kaspersky Lab application allows scanning boot sectors for viruses and disinfecting them if an infection is found.
A situation when a Kaspersky Lab application considers a non-infected object to be infected because the object's code is similar to that of a virus.
A technology for detecting threats about which information has not yet been added to Kaspersky Lab databases. The heuristic analyzer detects objects whose behavior in the operating system may pose a security threat. Objects detected by the heuristic analyzer are considered to be probably infected. For example, an object may be considered probably infected if it contains sequences of commands that are typical of malicious objects (open file, write to file).
A technology that allows increasing the speed of anti-virus scanning by excluding objects that have remained unchanged since their last scan, provided that the scan parameters (the databases and the settings) have not been altered. The information for each file is stored in a special database. This technology is used in both real-time protection and on-demand scan modes.
For example, you have an archive file that was scanned by a Kaspersky Lab application and assigned not infected status. Next time, the application will skip this archive unless the archive has been altered or the scan settings have been changed. If you have changed the archive content by adding a new object to it, modified the scan settings, or updated the application databases, the archive will be re-scanned.
Limitations of iChecker technology:
An anti-virus application from a third-party developer or a Kaspersky Lab application that does not support management through Kaspersky Free.
An object a portion of whose code completely matches part of the code of known malware. Kaspersky Lab does not recommend accessing such objects.
Kaspersky Lab HTTP servers from which updates of databases and software modules are downloaded.
The cloud-based knowledge base of Kaspersky Lab containing information about the reputation of applications and websites. Use of data from Kaspersky Security Network ensures faster responses by Kaspersky Lab applications to threats, improves the performance of some protection components, and reduces the likelihood of false positives.
A time period during which you have access to the application features and rights to use additional services.
A type of Internet fraud aimed at obtaining unauthorized access to users' confidential data.
An object whose code contains portions of modified code from a known threat, or an object whose behavior is similar to that of a threat.
Integral parts of Kaspersky Free intended for protection against specific types of threats (for example, Anti-Phishing). Each of the components is relatively independent of the other ones and can be disabled or configured individually.
A clearly defined and standardized set of rules governing the interaction between a client and a server. Well-known protocols and the services associated with them include HTTP, FTP, and NNTP.
A dedicated storage in which the application places backup copies of files that have been modified or deleted during disinfection. Copies of files are stored in a special format that is not dangerous for the computer.
A program or a set of programs for hiding traces of an intruder or malware in the operating system.
On Windows-based operating systems, a rootkit usually refers to a program that penetrates the operating system and intercepts system functions (Windows APIs). Interception and modification of low-level API functions are the main methods that allow these programs to make their presence in the operating system quite stealthy. A rootkit can usually also mask the presence of any processes, folders, and files that are stored on a disk drive, in addition to registry keys, if they are described in the configuration of the rootkit. Many rootkits install their own drivers and services on the operating system (these also are "invisible").
A small computer program or an independent part of a program (function) which, as a rule, has been developed to execute a specific task. It is most often used with programs that are embedded in hypertext. Scripts are run, for example, when you open some websites.
If real-time protection is enabled, the application tracks the execution of scripts, intercepts them, and scans them for viruses. Depending on the results of scanning, you may block or allow the execution of a script.
The security level is defined as a predefined collection of settings for an application component.
The set of programs needed to start and correctly operate the operating system and software installed on your computer. These objects are executed every time the operating system is started. There are viruses capable of infecting autorun objects specifically, which may lead, for example, to blocking of operating system startup.
The functions of the Kaspersky Lab application are implemented in the form of tasks, such as: Full Scan task or Update task.
Application settings that are specific for each task type.
Running the application in debugging mode; after each command is executed, the application is stopped, and the result of this step is displayed.
Real-time scanning that uses information from the current (latest) version of the databases for objects transferred over all protocols (for example, HTTP, FTP, and other protocols).
A new virus about which there is no information in the databases. Generally, unknown viruses are detected by the application in objects by using the heuristic analyzer. These objects are classified as probably infected.
The procedure of replacing / adding new files (databases or application modules) retrieved from the Kaspersky Lab update servers.
A file package designed for updating databases and application modules. The Kaspersky Lab application copies update packages from Kaspersky Lab update servers and automatically installs and applies them.
A program that infects other programs, by adding its code to them in order to gain control when infected files are run. This simple definition allows identifying the main action performed by any virus: infection.
A flaw in an operating system or an application that may be exploited by malware makers to penetrate the operating system or application and corrupt its integrity. Presence of a large number of vulnerabilities in an operating system makes it unreliable, because viruses that penetrate the operating system may cause disruptions in the operating system itself and in installed applications.
