It is believed that many inexperienced people are at a loss about whether word files will be infected with word virus. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Word files can be infected with word macro virus.

Word Macro virus is a collection of one or more virus macros made by professionals who make use of the openness of MICROSOFTWord, that is, the WordBASIC programming interface provided by Word. This set of virus macros affects computer use, and can be copied and transmitted through DOC documents and DOT templates.

Characteristics of Macro virus:

1. The spread is extremely fast:

The Word macro virus copies and spreads itself through DOC documents and DOT templates, and computer documents are the most widely communicated file types. Over the years, most people attach importance to protecting the boot part and executable files of their computers from being infected by viruses, while they browse and use foreign documents directly, which brings a lot of convenience to the spread of Word macro viruses. In particular, the popularity of Internet network and a large number of applications of E-mail pave the way for the spread of Word macro virus.

2. It is convenient to make and mutate.

Word uses the macro language WordBasic to write macro instructions. Macro viruses are also written in WordBasic

At present, there are dozens of macro virus prototypes in the world, and their variants are increasing day by day. The reason is still due to the openness of Word. Today's Word viruses are written in Wordbasic language, most Word virus macros do not use the Execute-Only handler provided by Word, they are still in a state of open reading and modification.

All users can easily see the full face of this macro virus in the macro menu of the Word tool. Of course, there will be "outlaws" who use the Basic sentences to change the activation and destruction conditions of the virus, and immediately produce a new macro virus, which is even more harmful than the original virus.

3. There is a great possibility of destruction:

In view of the fact that the macro virus is written in Wordbasic language, WordBasic language provides many system-level low-level calls, such as directly using DOS system commands, calling WindowsAPI, calling DDE, DLL and so on. These operations may pose a direct threat to the system, but Word has a weak ability to detect the security and integrity of instructions, and the instructions that destroy the system can be easily executed. The macro virus Nuclear is a typical example of destroying the operating system.

According to the transmission mechanism of macro virus, it is not difficult to see the characteristics of macro virus infection, so it is found that macro virus can be carried out through the following steps:

1, in their own use of Word to open the tool in the macro menu, point in the general (Normal) template, if you find that there are "AutoOpen" and other automatic macros, "FileSave" and other file operation macros or some strange names of macros, and they do not load a special template, it is possible to have a virus. Because most users have no macros in their Normal templates

2. If you find that a document is opened, it will be saved immediately without any changes, or it may be that Word has a virus.

3, open files with the suffix DOC in the Save menu can only be saved as a template, while the general template contains macros, it is also possible that Word has a virus.

The way to manually remove macro viruses:

1. Open the macro menu and delete the macros that you think are viruses in the generic template.

2. Open the document (template) with the virus macro, then open the macro menu, and delete the macro that you think is a virus in the generic template and the virus file name template.

3. Save clean documents.

Manual removal of viruses is always cumbersome and unreliable. Using antivirus tools to automatically remove macro viruses is an ideal solution.
