An applet is any miniature application transported over the Internet, especially as an enhancement to a web page. Authors often embed applets within the HTML page as a foreign program type. Java applets are usually only allowed to access certain areas of the user's system. Computer programmers often refer to this area as the sandbox.

Anti-virus viruses specifically look for and remove other viruses.

ASCII files are usually text files consisting of only ASCII characters. With effort, it is possible to write program files consisting only of printable characters (See: EICAR Standard Anti-virus Test File). Windows® batch (BAT) files and Visual Basic Script (See: Batch Files, VBS) files are also typically pure text, and program files. Because of the danger macro viruses can pose, using ASCII files in email communications may by less risky. While it is possible for ASCII files to contain program code, and thus to contain viruses, ASCII files let you control both content and layout exactly, ensuring your email is legible by the most email programs.

An armored virus tries to prevent analysts from examining its code. The virus may use various methods to make tracing, disassembling, and reverse engineering its code more difficult.

Anti-virus software scans a computer's memory and disk drives for viruses. If it finds a virus, the application informs the user and may clean, delete, or quarantine any files, directories, or disks affected by the malicious code. Also see: anti-virus scanner.

Anti-antivirus viruses attack, disable, or infect specific anti-virus software. Also see: retrovirus.

Refers to a coding system that assigns numerical values to characters such as letters, numbers, punctuation, and other symbols. Basic ASCII allows only 7 bits per character (for a total of 128 characters). The first 32 characters are "unprintable" (line feed, form feed, etc. ). Extended ASCII adds an additional 128 characters that vary between computers, programs and fonts. Computers use these extra characters for accented letters, graphical characters or other special symbols.

An algorithm is a sequence of steps needed to solve logical or mathematical problems. Certain cryptographic algorithms are used to encrypt or decrypt data files and messages and to sign documents digitally.

Adware is a legitimate, non-replicating program designed to display ads to the end user, often based on monitoring of browsing habits, and often in exchange for the right to use a program without paying for it (a take on the shareware concept).

ActiveX controls are software modules based on the Microsoft® Component Object Model (COM) architecture. They add functionality to software applications by seamlessly incorporating pre-made modules with the basic software package. Modules can be interchanged but still appear as parts of the original software. On the Internet, ActiveX controls can be linked to web pages and downloaded by an ActiveX-compliant browser. ActiveX controls turn web pages into software pages that perform like any other program launched from a server. ActiveX controls can have full system access. In most instances this access is legitimate, but one should be cautious of malicious ActiveX applications.
