Glossary

Term	Definition
Active	This refers to the device currently in use.
ActiveUpdate	ActiveUpdate is a function common to many Trend Micro products. Connected to the Trend Micro update website, ActiveUpdate provides up-to-date downloads of virus pattern files, scan engines, program, and other Trend Micro component files through the Internet or the Trend Micro Total Solution CD.
ActiveX	A type of open software architecture that implements object linking and embedding, enabling some of the standard interfaces, such as downloading of web pages.
ActiveX malicious code	An ActiveX control is a component object embedded in a web page which runs automatically when viewing the page. ActiveX controls allow web developers to create interactive, dynamic web pages with broad functionality such as HouseCall, Trend Micro's free online scanner. Hackers, virus writers, and others who want to cause mischief or worse may use ActiveX malicious code as a vehicle to attack the system. Change the browser's security settings to "high" so that these ActiveX controls do not execute.
Address	Refers to a networking address (see IP address) or an email address, which is the string of characters that specify the source or destination of an email message.
Administrator	Refers to “system administrator"—the person in an organization who is responsible for activities such as setting up new hardware and software, allocating user names and passwords, monitoring disk space and other IT resources, performing back ups, and managing network security.
Administrator account	A user name and password that has administrator-level privileges.
Administrator email address	The address used by the administrator of your Trend Micro product to manage notifications and alerts.
Adware	Advertising-supported software in which advertising banners display while the program is running. See also Spyware.
Alert	A message intended to inform a system's users or administrators about a change in the operating conditions of that system or about some kind of error condition.
Antivirus	Computer programs designed to detect and clean computer viruses.
Archive	A single file containing one or (usually) more separate files plus information to allow them to be extracted (separated) by a suitable program, such as a .zip file.
Attachment	A file attached to (sent with) an email message.
Authentication	The verification of the identity of a person or a process. Authentication ensures that the system delivers the digital data transmissions to the intended receiver. Authentication also assures the receiver of the integrity of the message and its source (where or whom it came from). The simplest form of authentication requires a user name and password to gain access to a particular account. Other authentication protocols are secret-key encryption, such as the Data Encryption Standard (DES) algorithm, or public-key systems using digital signatures. Also see public-key encryption and digital signature.
Boot sector	A sector is a designated portion of a disk (the physical device from which the computer reads and writes the data on). The boot sector contains the data used by your computer to load and initialize the computer’s operating system.
Boot sector virus	A boot sector virus is a virus targeted at the boot sector (the operating system) of a computer. Computer systems are most vulnerable to attack by boot sector viruses when you boot the system with an infected disk from the floppy drive - the boot attempt does not have to be successful for the virus to infect the hard drive. Also, there are a few viruses that can infect the boot sector from executable programs. These are multi-partite viruses and they are relatively rare. Once the system is infected, the boot sector virus will attempt to infect every disk accessed by that computer. In general, most antivirus software can successfully remove boot sector viruses.
Bridge	A device that forwards traffic between network segments based on data link layer information. These segments have a common network layer address.
Browser	A program that allows a person to read hypertext, such as Internet Explorer. The browser gives some means of viewing the contents of nodes (or "pages") and of navigating from one node to another. A browser acts as a client to a remote web server.
Cache	A small fast memory, holding recently accessed data, designed to speed up subsequent access to the same data. The term is most often applied to processor-memory access, but also applies to a local copy of data accessible over a network.
COM file infector	An executable program with a .com file extension. Also see DOS virus.
Compressed file	A single file containing one or more separate files plus information for extraction by a suitable program, such as WinZip.
Configuration	Selecting options for how your Trend Micro product will function, for example, selecting whether to quarantine or delete a virus-infected email message.
Cookie	A mechanism for storing information about an Internet user, such as name, preferences, and interests, which is stored in your web browser for later use. The next time you access a website for which your browser has a cookie, your browser sends the cookie to the web server, which the web server can then use to present you with customized web pages. For example, you might enter a website that welcomes you by name.
Daemon	A program not explicitly invoked, but lays dormant waiting for some condition(s) to occur. The perpetrator of the condition need not be aware that a daemon is lurking.
Default	A value that pre-populates a field in the management console interface. A default value that represents a logical choice and provided for convenience. Use default values as-is, or change them.
Denial of Service (DoS) attack	Group-addressed email messages with large attachments that clog your network resources to the point where messaging service is noticeably slow or even stopped.
Dialer	A type of Trojan that, when executed, connects the user's system to a pay-per-call location in which the unsuspecting user is billed for the call without his or her knowledge.
Digital signature	Extra data appended to a message which identifies and authenticates the sender and message data using a technique called public-key encryption. Also see public-key encryption and authentication.
Directory	A node, which is part of the structure on a hierarchical computer file system. A directory typically contains other nodes, folders, or files. For example, C:\Windows is the Windows directory in the C drive.
Directory path	The subsequent layers within a directory where a file can be found, for example, the directory path for the ISVW for SMB Quarantine directory is: C:\Programs\Trend Micro\ISVW\Quarantine
Disclaimer	A statement appended to the beginning or end of an email message that states certain terms of legality and confidentiality regarding the message.
DNS	Domain Name System—A general-purpose data query service chiefly used in the Internet for translating host names into IP addresses.
DNS resolution	When a DNS client requests host name and address data from a DNS server, the process is called resolution. Basic DNS configuration results in a server that performs default resolution. For example, a remote server queries another server for data in a computer in the current zone. Client software in the remote server queries the resolver, which answers the request from its database files.
(Administrative) domain	A group of computers sharing a common database and security policy.
Domain name	The full name of a system, consisting of its local host name and its domain name, for example, tellsitall.com. A domain name should be sufficient to determine a unique Internet address for any host in the Internet. This process, called "name resolution", uses the Domain Name System (DNS).
DOS virus	Also referred to as “COM” and “EXE file infectors.” DOS viruses infect DOS executable programs- files that have the extensions .COM or .EXE. Unless they have overwritten or inadvertently destroyed part of the original program's code, most DOS viruses try to replicate and spread by infecting other host programs.
Download (verb)	To transfer data or code from one computer to another. Downloading often refers to transfer from a larger "host" system (especially a server or mainframe) to a smaller "client" system.
Dropper	Droppers are programs that serve as delivery mechanisms to carry and drop viruses, Trojans, or worms into a system.
Dynamic Host Configuration Protocol (DHCP)	A protocol for assigning dynamic IP addresses to devices in a network. With dynamic addressing, a device can have a different IP address everytime it connects to the network. In some systems, the device’s IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP addresses.
Encryption	Encryption is the process of changing data into a form that only the intended receiver can read. To decipher the message, the receiver of the encrypted data must have the proper decryption key. In traditional encryption schemes, the sender, and the receiver use the same key to encrypt and decrypt data. Public-key encryption schemes use two keys: a public key, which anyone may use, and a corresponding private key, possessed only by the person who created it. With this method, anyone may send a message encrypted with the owner's public key, but only the owner has the private key necessary to decrypt it. PGP (Pretty Good Privacy) and DES (Data Encryption Standard) are two of the most popular public-key encryption schemes.
Ethernet	A local area network (LAN) technology invented at the Xerox Corporation, Palo Alto Research Center. Ethernet is a best-effort delivery system that uses CSMA/CD technology. A variety of cable schemes can run over the Ethernet, including thick coaxial, thin coaxial, twisted pair, and fiber optic cable. Ethernet is a standard for connecting computers into a local area network. The most common form of Ethernet is the 10BaseT, which denotes a peak transmission speed of 10 Mbps using copper twisted-pair cable.

File-infecting virus	File-infecting viruses infect executable programs (generally, files that have extensions of .com or .exe). Most such viruses simply try to replicate and spread by infecting other host programs, but some inadvertently destroy the program they infect by overwriting a portion of the original code. Some of these viruses are very destructive and attempts to format the hard drive at a pre-determined time or perform some other malicious action. In many cases, you can successfully remove a file-infecting virus from the infected file. However, if the virus has overwritten part of the program's code, the original file will be unrecoverable
File type	The kind of data stored in a file. Most operating systems use the file name extension to determine the file type. The file type used to select an appropriate icon to represent the file in a user interface, and the correct application with which to view, edit, run, or print the file.
File name extension	The portion of a file name (such as .dll or .xml) which indicates the kind of data stored in the file. Apart from informing the user what type of content the file holds, file name extensions are typically used to decide which program to launch when a file is run.

This security protocol provides data encryption, server authentication, message integrity, and optional client authentication for a TCP/IP connection.
Sender	The person who is sending an email message to another person or entity.
Server	A program that provides some service to other (client) programs. The connection between client and server is normally by means of message passing, often over a network, and uses some protocol to encode the client's requests and the server's responses. The server may run continuously (as a daemon), waiting for requests to arrive, or it may be invoked by some higher-level daemon which controls a number of specific servers.
Signature	See virus signature.
SMTP	Simple Mail Transfer Protocol—A protocol used to transfer electronic mail between computers, usually over Ethernet. It is a server-to-server protocol but uses other protocols to access the messages.
SMTP server	A server that relays email messages to their destinations.

True file type	Used by IntelliScan, a virus scanning technology, to identify the type of information in a file by examining the file headers, regardless of the file name extension.
Trusted domain	A domain from which your Trend Micro product will always accept messages, without considering whether the message is spam. For example, a company called Dominion, Inc. has a subsidiary called Dominion-Japan, Inc. The dominion.com network always accepts messages from dominion-japan.com, without checking for spam, since the messages are from a known and trusted source.
Trusted host	A server allowed to relay mail through your network because they are trusted to act appropriately and not, for example, relay spam through your network.
URL	Universal Resource Locator—A standard way of specifying the location of an object, typically a web page, in the Internet, for example, www.trendmicro.com. The URL maps to an IP address using DNS.
VBscript virus	VBscript (Microsoft Visual Basic scripting language) is a simple programming language that allows web developers to add interactive functionality to HTML pages displayed in a browser. For example, developers might use VBscript to add a “Click Here for More Information” button on a web page. A VBscript virus is a virus targeted at the scripts in the HTML code. This enables the virus to reside in web pages and download to a user’s desktop through the user’s browser. Also see JavaScript virus.
Virtual Local Area Network (VLAN)	A logical (rather than physical) grouping of devices that constitute a single broadcast domain. You do not identify VLAN members by their location on a physical subnetwork but through the use of tags in the frame headers of their transmitted data. The IEEE 802.1Q standard describes VLANs more thoroughly.
Virus	A computer virus is a program – a piece of executable code – that has the unique ability to infect. Like biological viruses, computer viruses can spread quickly and are often difficult to eradicate. In addition to replication, some computer viruses share another commonality: a damage routine that delivers the virus payload. While payloads may only display messages or images, they can also destroy files, reformat your hard drive, or cause other damage. Even if the virus does not contain a damage routine, it can cause trouble by consuming storage space and memory, and degrading the overall performance of your computer.
Virus kit	A template of source code for building and executing a virus, available from the Internet.
Virus signature	A virus signature is a unique string of bits that identifies a specific virus. Virus signatures are stored in the Trend Micro virus pattern file. The Trend Micro scan engine compares code in files, such as the body of an email message, or the content of an HTTP download, to the signatures in the pattern file. If the scan engine finds a match, they will detect and act upon the virus (for example, cleaned, deleted, or quarantined) according to your security policy.
Virus writer	Another name for a computer hacker, someone who writes virus code.
Web	The World Wide Web, also called the web or the Internet.
Wildcard	A term used in reference to content filtering, where an asterisk () represents any characters. For example, in the expression ber, this expression can represent barber, number, plumber, timber, and so on. The term originates from card games, in which a specific card, identified as a "wildcard," can be used for any number or suit in the card deck.
Worm	A self-contained program (or set of programs) that is able to spread functional copies of itself or its segments to other computer systems.
Zip file	A compressed archive (in other words, “zip file") from one or more files using an archiving program such as WinZip.
