Real-time Scanner

An anti-virus software application that operates as a background task, allowing the computer to continue working at normal speed, with no perceptible slowing. See Also: On-Access Scanner

Redirect

The action used by some viruses to point a command to a different location. Often this different location is the address of the virus and not the original file or application.

Rename

The action by which a user or program assigns a new name to a file. Viruses may rename program files and take the name of the file so running the program inadvertently runs the virus.

Anti-virus programs may rename infected files so the are unusable until they are manually cleaned or deleted.

Replication

The process by which a virus makes copies of itself in order to carry out subsequent infections. Replication is one of major criteria separating viruses from other computer programs.

Reset

To restart a computer without turning it off. Also: Warm Boot

Resident Virus

A resident virus loads into memory and remains inactive until a trigger event. When the event occurs the virus activates, either infecting a file or disk, or causing other consequences. All boot viruses are resident viruses and so are the most common file viruses.

Resident Extension

A resident extension is a memory-resident portion of a program that remains active after the program ends. It essentially becomes an extension to the operating system. Many viruses install themselves as resident extensions.

Rogue Program

A term the media use to denote any program intended to damage programs or data, or to breach a system's security. It includes Trojan Horse programs, logic bombs, viruses, and more.

RTF File

Rich Text Format File. An alternative format to the DOC file type supported by Microsoft Word. RTF files are ASCII text files and include embedded formatting commands. RTF files do not contain macros and cannot be infected with a macro virus.

This makes RTF files a good document format for communicating with others via e-mail. However, some macro viruses attempt to intercept saving a file as an RTF file and instead save it as a DOC file with an RTF extension. Users can catch this trick by first reading the file in a simple text editor like Notepad. DOC files will be nearly unreadable, while RTF files will be readable. This file type has the extension RTF.
