A quine's output is exactly the same as its source code. A quine is a computer program that takes no input and produces a copy of its own source code as its only output. The standard terms for these programs in the computability theory and computer science literature are "self-replicating programs", "self-reproducing programs", and "self-copying programs".
A source file can be overwritten such that it includes a call to some malicious code. By targeting a generic programming language, such as C, source code viruses can be very portable. Source code viruses are rare, partly due to the difficulty of parsing source code programmatically, but have been reported to exist. One such virus (W32/Induc-A ...
A computer virus [1] is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs. [ 2 ] [ 3 ] If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses .
Metamorphic code can also mean that a virus is capable of infecting executables from two or more different operating systems (such as Windows and Linux) or even different computer architectures. Often, the virus does this by carrying several viruses within itself. The beginning of the virus is then coded so that it translates to correct machine ...
Code injection is a computer security exploit where a program fails to correctly process external data, such as user input, causing it to interpret the data as executable commands. An attacker using this method "injects" code into the program while it is running.
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses.Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source.

Duqu is a collection of computer malware discovered on 1 September 2011, thought by Kaspersky Labs to be related to the Stuxnet worm [1] and to have been created by Unit 8200. [2] [3] Duqu has exploited Microsoft Windows's zero-day vulnerability.
