Definition
Virulent code / pest ( malicious codes or shortened by malcodes) defined as all kinds of program, macro or script which can execution and made as a mean to destroy computer system. Therefore bug made involuntaryly by programer, do not the included in this category. But for really bug bother, many people categorize it as malcode
Ahead used by term " Malware (= Malicious Software)" addressed for malcode. But this term is too weak and narrow, so that the spurious e-mail / lie which notabene of non software cannot be packed into by this faction. Is therefore used by term malcode, non malware.

Classification
Pest code can be classified in 3 kinds of faction: virus, worm and Trojan Horses, and also some program owning bug.
Virus
Virus own virulent ability to reproduce themselves and consisted of by the code goals modification code corps which which can is walk, or earn also the internal structure modification of code goals, so that the code goals of before walking forced to run virus.Virus often present unwelcome message, ruined of display appearance, vanishing memory C-Mos, ruined of information in hard disk etc. the Effect generated by a virus experience of growth which serious enough latterly.
Example the virus: Brain, Ohe half, Die hard, XM/Laroux, Win95/CIH.
Virus admit of divided again in a few category :
1. Boot Virus: If computer flamed, a initial program in boot sector will be run. Virus residing in boot sector referred as by boot virus.
2. Virus File: File of Virus is virus which infection of executable program. Reported by that almost 80% virus is virus file.
3. Multipartite Virus: Virus which the good infection of boot sector and file.
4. Macro Virus: met Latter.Its goals non executable program, but file dokument of like Microsoft Excel or Word. He will start infection if application program read containing document of macro.
Worm
Worm addressed to program copying his self to ONLY memory computer. Elementary difference from worm virus and is, what goals code infection or do not. goals code Infection virus, but worm do not. Worm only ngendon in memory
Worm initially met in large computer ( 1970-an), and final- just this met in small computer like PC. Especially since 1999, where work of a lot of circulating through enamel media
Example worm: I-Worm/Happy99(Ska), I-Worm/ExploreZIP, I-Worm/PrettyPark, I-Worm/MyPics
Trojan Horse
Trojan Horse produced virulent with an eye to. Differ from virus, Trojan Horse cannot produce ownself. Generally, they are brought by utility of other program. Utility of the Program contain x'self, or Trojan Horse of itself also " proud of " as utility program.
Example Trojan Horse: Win-Trojan/Back Orifice, Win-Trojan/SubSeven, Win-Trojan/Ecokys(Korean)
Trojan Horse admit of divided again become :
1. pack of Of Trojan Horse: Trojan Horse which walk in PACK. He Lessen speed of computer or vanish of file of on or the certain situation.
2. Windows Trojan Horse: Run in system Microsoft Windows. Sum Up Windows Trojan Horse mount since 1998 and used as by a program for hacking with an eye to the criminal which can collect information from computer jointed by internet.
