A few years ago Microsoft disabled Macro in Microsoft Office by default because of Macro viruses. Macro is a very powerful and productive tool for Microsoft Office because it helps users automate simple and complex tasks in Microsoft Office. But, this productive tool was misused by cyber-criminals, who realized that they could use it to download and infect their victims' computers with malware. So, due to this threat, Microsoft disabled Macro in Microsoft Office by default and gave users the ability to enable it, if the document that they are opening is a trusted one.
Microsoft Word or Excel Prompting a User to enable Macro via “Enable Content” or "Enable Editing"
How to Protect Yourself
If you are sent an unexpected email message with an attached Microsoft Word or Excel document, ask to open the document, and then ask to "Enable Content" or "Enable Editing" in order to view the content, please delete the document. Enabling Macro via "Enable Content" will run or execute the malicious code or Macro, which will download and install Trojan horse, viruses or other malware on your computer.
Once your computer has become infected, especially with a Trojan horse, the cybercriminals behind the email message will be able to access and take control of your computer remotely from anywhere around the world. They may spy on you, use your computer to commit cybercrimes, or steal your personal and financial information.
Please note that Macro viruses also affect Microsoft Powerpoint.
If you were tricked into opening a malicious Microsoft Word or Excel document and enabling Macro or "Content", we recommend doing a full scan of your computer with the antivirus software installed on it.
