Microsoft™ Object Linking and Embedding (OLE) allows embedding Microsoft Office™ files within themselves. This means that you could have a
Microsoft Word document inside an Excel spread sheet, and in turn this Excel spread
sheet could
be embedded in a Microsoft™ PowerPoint presentation.
OLE offers a large number of benefits to developers, at the same time it can lead
to potential
infection. To address this issue, Trend Micro has added a new scan feature "OLE layer
scan"
that complements state-of-the-art ServerProtect virus protection. See Scanning Viruses.

TipOLE layer scan offers five layers of protection. Trend Micro recommends a setting of two OLE layers for Scan Now and a setting of one for
a Real-time Scan. A lower setting will improve server performance.
