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
This macro virus infects MS Word documents and normal.dot template files. The virus itself is a macro named 'AntiTheSecond' and it seems that the author intended it to act as an antivirus against the macro virus TheSecond.
When an infected file or template is opened, the virus creates an export file named Anti.tmp in the MS Word start directory. The macro code is saved in this file. The virus then checks all MS Word documents which are currently open for the macro module of TheSecond virus. If this module is detected, the virus will cause a MessageBox to be displayed. The MessageBox contains the following text in Russian:
��������� ����� The Second � ��������� <��� �����> !
Translation: The Second has been detected in the document 'name of file'!
It then deletes the contents of the virus module, without deleting the module TheSecond (which is a type of vaccine for files). If this is successfully completed, a MessageBox in Russian will be displayed on the screen:
�������� <��� �����> �������!
Translation: The document
If the document does not contain the virus TheSecond, Antisec will infect it by writing its code to the document from the file Anti.tmp. A MessageBox in Russian will then be displayed on the screen:
��������� �������� � �������� <��� �����> !!!
Translation: An antivirus has been added to the document
