SharePoint Shield

This Article Applies to:

  • Avast Business Hub


The SharePoint component for Windows Servers is specifically meant to protect your SharePoint Server from threats without interfering in its function. It is a security plugin that you install on your SharePoint server. SharePoint Shield will scan all uploaded and downloaded files to prevent malicious documents from infecting your business data and it will block ransomware attacks. If the plugin discovers a harmful document, it will quarantine it and alert the user.

Supported SharePoint Versions

Microsoft SharePoint server versions 2010 and later are supported.


SharePoint must be installed prior to installing Avast Business Antivirus in order for the application to be detected and the plugin installed.

If SharePoint is installed afterward, the SharePoint component would need to be added via policies.

Configuring SharePoint Shield Settings

To access SharePoint Shield settings:

  1. Open the Policies page
  2. Click the desired policy to open its Detail drawer
  3. Click the Settings tab, then Antivirus
  4. Expand the SharePoint section (under Data Protection)

Two sets of settings are available here:

  • Resident task settings
  • Packers

Resident Task Settings Tab

Here, you can define how SharePoint handles an uncleanable object. It can either deny access to or replace the object with a warning.

Any malicious activity detected will be written to the Windows Event Log - you can select several logging options:

  • Low: Errors & viruses only
  • Normal: Warning, errors, & viruses
  • High: For more detail in Avast logs
  • Maximum: For the max detail in Avast logs

Packers Tab

These settings allow you to choose which archive (packer) files Avast should try to unpack during the scanning process (unpacked files can be better analyzed for malware). Unpacking a file is the same as extracting a file from an archive. Original archives remain intact while processed by SharePoint Shield.
