Understanding Malicious Files in Microsoft 365 Services

In today’s digital landscape, safeguarding your data is paramount. SharePoint Online, OneDrive, and Microsoft Teams are essential tools for collaboration and file management within Microsoft 365. However, these platforms can sometimes harbor malicious files that pose significant security risks. Understanding how to identify and remove these threats is crucial for maintaining a secure environment.

Why Are Files Blocked in SharePoint, OneDrive, and Teams?

Microsoft 365 employs robust security measures to protect users from malware and other threats. When a file is suspected of containing malicious content, it is automatically blocked to prevent potential damage. This protective action ensures that users cannot open or share compromised files, safeguarding both individual and organizational data.

Note: A blocked file is typically marked with a warning icon next to its name, indicating that it has been identified as potentially harmful.

Steps to Remove Malicious Files

1. Delete the Malicious File

The most straightforward way to eliminate the threat is by deleting the file. This action ensures that the malicious content is no longer accessible within your organization’s environment.

On Desktop:
Navigate to the file in SharePoint, OneDrive, or Teams.
Select the file and choose the Delete option.
On Mobile App:
Open the OneDrive mobile app.
Select the More icon next to the problematic file.
Choose Delete.

2. Download and Clean the File (If Permitted)

If your organization allows, you can download the file to your local machine for further analysis and cleaning.

Steps to Download:
Go to Office.com and sign in with your work or school account.
- For Microsoft 365 operated by 21Vianet in China, use login.partner.microsoftonline.cn.
- For Microsoft 365 Germany, use portal.office.de.
Navigate to OneDrive.
Select the malicious file and click Download.

Caution: Ensure that your computer has up-to-date security software before attempting to clean the downloaded file.

3. Consult Your Microsoft 365 Administrator

If you believe the file has been incorrectly flagged, contact your Microsoft 365 administrator. They have the tools to investigate and, if necessary, unblock the file.

Preventing Future Malware Infections

Proactive measures can significantly reduce the risk of encountering malicious files:

Maintain Updated Security Software:
Regularly update antivirus and anti-malware programs to protect against the latest threats.
Install Software Updates:
Keep all devices and applications updated to patch vulnerabilities.
Exercise Caution with Email Attachments:

Ensure that all users are aware of best practices for cybersecurity.
