A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also commonly but erroneously used to refer to other types of malware including but not limited to adware and spyware programs that do not have the reproductive ability.

The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low level commands regardless of the system's state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem.

To be able to use this functionality the CONFIG_MAGIC_SYSRQ option has to be enabled at kernel compile time.
