    • 17 May 2019
    • Product/Version:
    • PortalProtect 2.5
    • Platform:

Summary

PortalProtect is not able to detect application/executable files when they are embedded as an object inside a Microsoft Word/Excel file.

This is an expected scenario because the Attachment Blocking OLE Scan feature is disabled by default.

Enabling the Attachment Blocking OLE Scan feature will fix this issue. Do the following:

To enable this feature, do the steps below:
  1. Open Registry Editor.
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PortalProtect\CurrentVersion.
  3. Create the following key:
    Name: ABOLEScanLayer (to enable OLE Scan feature)
    Type: Dword (32Bit Value)
    Value: 0 – 20 (0: means disabled, 1-20: means enabled & max scan layer)
    Example: ABOLEScanLayer = 1

By default, Attachment Blocking OLE Scan will check the following file types:

  • Word
  • Powerpoint
  • Excel
  • Project
  • Office 2007 files
  • PDF

To customize which file types will be scanned, perform the following steps:
