For example:
The number of layers you specify is 2. Embedded within a file is a Microsoft Word
document (first layer), within the Word document is a Microsoft Excel spreadsheet
(second layer), and within the spreadsheet is an .exe file (third layer). OfficeScan
will scan the Word document and Excel spreadsheet, and skip the .exe file.
• Detect exploit code in OLE files: OLE Exploit Detection heuristically
identifies malware by checking Microsoft Office files for exploit code.
Note: The specified number of layers is applicable to both Scan OLE objects and
Detect exploit code options.
• Enable IntelliTrap: Detects and removes virus/malware on compressed
executable files. This option is available only for Real-time Scan. See IntelliTrap on
page C-5 for details.
• Scan boot area: Scans the boot sector of the client computer’s hard disk for
virus/malware during Manual Scan, Scheduled Scan and Scan Now
CPU Usage
OfficeScan can pause after scanning one file and before scanning the next file. This
setting is used during Manual Scan, Scheduled Scan, and Scan Now.
Select from the following options:
• High: No pausing between scans
• Medium: Pause between file scans if CPU consumption is higher than 50%, and do
not pause if 50% or lower
• Low: Pause between file scans if CPU consumption is higher than 20%, and do not
pause if 20% or lower
If you choose Medium or Low, when scanning is launched and CPU consumption is
within the threshold (50% or 20%), OfficeScan will not pause between scans, resulting
in faster scanning time. OfficeScan uses more CPU resource in the process but because
CPU consumption is optimal, computer performance is not drastically affected. When
CPU consumption begins to exceed the threshold, OfficeScan pauses to reduce CPU
usage, and stops pausing when consumption is within the threshold again.
