Virus Computer 2

After we know what such with the virus and also history, now we have to know the virus type. Virus can be classified to become six faction:

1) Macro Virus
Writed by using macro Ianguage pemrograman [which is made moderate, and infection of application of Microsoft Office, like Word and Excel, and in this time estimated by 75 percentage of this virus type have been gone the round of world. A document which infection by macro virus in general comand modification which will there have and a lot of used ( like comand " Save") to trigger the spreading of the comand moment x'self run.
Example:
=> variant W97M, misal W97M.Panther
long 1234 bytes,
=> WM.Twno.A;TW
long 41984 bytes,

2) Virus of Boot Sector
Virus Boot sector have common once disseminate. This virus in duplicating x'self will remove or replace the original boot sector with the program of booting virus. So that moment happened by the booting hence virus will load to memory and hereinafter virus will have the ability control the hardware standar(ex::monitor, etc) and from this memory also virus will disseminate all the existing drive and incircuit to computer ( ex: floopy, drive [of] besides the drive c). virus Boot-Sector Include the x'self into boot - sector -- a area of hard drive ( or other disk type) to be accessed first time moment PC flamed. Virus of this type of can hinder Our PC to conduct the booting from hard disk.
Example:
=> varian virus wyx , example: wyx.C(B) infection of boot record and floopy.
long 520 bytes,

3) Stealth Virus
This virus will master the tables of tables interupt at PACK which often we recognize by " Interrupt interceptor". this virus capable to control the instruction of instruction of level PACK and usually occult them by name nya either through full and or its size measure . Stealth Virus always hide out its by making file which visible infection [do] not infection, but virus of this type of seldom able to face the newest scanner antivirus.
Example:
=> Yankee.XPEH.4928. Infection file *.COM dan *.EXE
long 4298 bytes

4) Polymorphic Virus
This virus designed to make to deceive the program antivirus, its meaning this virus always try in order not to be recognized by antivirus by always fox change its structure each time finish the file infection / program other;dissimilar. Polymorphic will alter the code of moment x'self overcome at different machine; theoretically virus this type of harder to can be detected by scanner antivirus, but in in reality virus of this type is not writed better, so that easy to in order to be known its existence virus Will alter the code of moment x'self overcome at different machine; theoretically virus this type of harder to can be detected by scanner antivirus, but in in reality virus of this type of not writed better, so that easy to in order to be known its existence.
Example:
=> Necropolis A/B, Infection file *.COM dan *.EXE
long 1963 bytes.

5) Virus File/Program
This virus infection of file file which can be executed direct the than operating system, good that file application (*. EXE), and also *. COm usually also result of infection from this virus knowable by changing size measure of file attacked. This virus do to execute to propagate the x'self at related/relevant document and application with of file moment which infection opened or run.

6) Or multipartite virus represent the merger from Virus of Boot sector and file Virus: its meaning work conducted cause two, that is he/she infection can file *. EXE as well as infection of Boot Sector. good Multi Partition Infection virus file and boot-sector--sebuah of criminal of have mask to our system infection which can continuously before be under arrest by scanner antivirus.
