Parent class: VirWare
Viruses and worms are malicious programs that self-replicate on computers or via computer networks without the user being aware; each subsequent copy of such malicious programs is also able to self-replicate. Malicious programs which spread via networks or infect remote machines when commanded to do so by the “owner” (e.g. Backdoors) or programs that create multiple copies that are unable to self-replicate are not part of the Viruses and Worms subclass. The main characteristic used to determine whether or not a program is classified as a separate behaviour within the Viruses and Worms subclass is how the program propagates (i.e. how the malicious program spreads copies of itself via local or network resources.) Most known worms are spread as files sent as email attachments, via a link to a web or FTP resource, via a link sent in an ICQ or IRC message, via P2P file sharing networks etc. Some worms spread as network packets; these directly penetrate the computer memory, and the worm code is then activated. Worms use the following techniques to penetrate remote computers and launch copies of themselves: social engineering (for example, an email message suggesting the user opens an attached file), exploiting network configuration errors (such as copying to a fully accessible disk), and exploiting loopholes in operating system and application security. Viruses can be divided in accordance with the method used to infect a computer:- file viruses
- boot sector viruses
- macro viruses
- script viruses
Class: Virus
Viruses replicate on the resources of the local machine. Unlike worms, viruses do not use network services to propagate or penetrate other computers. A copy of a virus will reach remote computers only if the infected object is, for some reason unrelated to the virus function, activated on another computer. For example: when infecting accessible disks, a virus penetrates a file located on a network resource a virus copies itself to a removable storage device or infects a file on a removable device a user sends an email with an infected attachment.Read more

Microsoft Word (MS Word) is a popular word processor and part of Microsoft Office. Microsoft Word files have a .doc or .docx extension.Description
Technical Details
It is stealth macro virus. It contains seven macros in one module "AuAhGelap": AutoOpen, AutoClose, Au, Ah, ToolsMacro, Gelap, ViewVBCode.
It infects the global macros area on opening an infected document (AutoOpen) and infects other documents on opening and closing (AutoOpen, AutoClose).
The virus turns off the Word virus protection (the VirusProtection option). It also disables the Tools/Macro menus and Visual Basic Editor (stealth).
Before infection the virus checks user name and if it is not "Sembako" displays the baloon:
HelloSorry, but your Microsoft Word doesn't belong to you any more. Now it is mine!!
After that the virus changes user name to "Sembako" and user initials to "SBK".
Between 8:00am and 9:00am the virus displays the message:
Selamat pagi Selamat pagi cewek-cewek yang cakep-cakep.Between 12:00pm and 2:00pm the it displays:
