Freddy employed which type of virus that infects Microsoft Word document files using VBA?

1. Macro virus

2. Cavity virus

3. Logic bomb virus

4. Rootkit virus

The correct answer is: Macro virus

The type of virus that Freddy employed, which specifically infects Microsoft Word document files using Visual Basic for Applications (VBA), is categorized as a macro virus. Macro viruses target applications that support macros, such as Microsoft Word and Excel. They exploit the macro capabilities in these programs to automatically execute malicious code when the document is opened. Macro viruses can spread easily because they are often embedded within document files, making them appear harmless to unsuspecting users. Once the document is opened and macros are enabled, the virus can execute and potentially replicate itself to other documents or systems. Other types of viruses mentioned have different characteristics and behaviors. For example, cavity viruses hide within the unused spaces of host files and may not specifically target document files. Logic bomb viruses are designed to execute under specific conditions but aren't tied to the macro functions of Microsoft Office applications. Rootkits are a set of tools used to gain unauthorized access and maintain control over a computer system, typically by disguising themselves, and they operate at a much deeper level compared to document-based macro viruses. In summary, the macro virus is the correct classification for the type of virus that infects Word documents using VBA due to its unique interaction with the macro capabilities of these applications.
