scancrit
Specify which files a particular scan type should scan using file attributes such as file type and extension. Also specify conditions that will trigger scanning. For example, configure Real-time Scan to scan each file after it is downloaded to the computer.
Choose activities on files that will trigger Real-time Scan. Select from the following options:
Scan files being created/modified: Scans new files introduced into the computer (for example, after downloading a file) or files being modified
Scan files being retrieved: Scans files as they are opened
Scan files being created/modified and retrieved
For example, if the third option is selected, a new file downloaded to the computer will be scanned and stays in its current location if no security risk is detected. The same file will be scanned when a user opens the file and, if the user modified the file, before the modifications are saved.
Select from the following options:
All scannable files: Scan all files
File types scanned by IntelliScan: Only scan files known to potentially harbor malicious code, including files disguised by a harmless extension name. See IntelliScan for details.
Files with certain extensions: Only scan files whose extensions are included in the file extension list. Add new extensions or remove any of the existing extensions.
Select one or more of the following options:
Scan network drive: Scans network drives or folders mapped to the client computer during Manual Scan or Real-time Scan.
Scan hidden folders: Allows OfficeScan to detect and then scan hidden folders on the computer during Manual Scan
Scan the boot sector of the USB storage device after plugging in: Automatically scans only the boot sector of a USB storage device every time the user plugs it in.
Scan compressed files: Allows OfficeScan to scan up to a specified number of compression layers and skip scanning any excess layers. OfficeScan also cleans or deletes infected files within compressed files. For example, if the maximum is two layers and a compressed file to be scanned has six layers, OfficeScan scans two layers and skips the remaining four. If a compressed file contains security threats, OfficeScan cleans or deletes the file.
OfficeScan treats Microsoft Office 2007 files in Office Open XML format as compressed files. Office Open XML, the file format for Office 2007 applications, uses ZIP compression technologies. If you want files created using these applications to be scanned for viruses/malware, you need to enable scanning of compressed files.
Scan floppy disk during system shutdown: Scans any floppy disk for boot viruses before shutting down the computer. This prevents any virus/malware from executing when a user reboots the computer from the disk.
Scan OLE objects: When a file contains multiple Object Linking and Embedding (OLE) layers, OfficeScan scans the specified number of layers and ignores the remaining layers.
All clients managed by the server check this setting during Manual Scan, Real-time Scan, Scheduled Scan, and Scan Now. Each layer is scanned for virus/malware and spyware/grayware.
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.
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 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
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.
If you choose High, OfficeScan does not check the actual CPU consumption and scans files without pausing.
Configure how often (daily, weekly, or monthly) and what time Scheduled Scan will run.
For monthly Scheduled Scans, you can choose either a particular day of a month or a day of a week and the order of its occurrence.
A particular day of a month: Select between the 1st and 31st day. If you selected the 29th, 30th, or 31st day and a month does not have this day, OfficeScan runs Scheduled Scan on the last day of the month. Therefore:
If you selected 29, Scheduled Scan runs on February 28 (except on a leap year) and on the 29th day of all the other months.
If you selected 30, Scheduled Scan runs on February 28 or 29, and on the 30th day of all the other months.
If you selected 31, Scheduled Scan runs on February 28 or 29, April 30, June 30, September 30, November 30, and on the 31st day of all the other months.
A day of a week and the order of its occurrence: A day of a week occurs four or five times a month. For example, there are typically four Mondays in a month. Specify a day of a week and the order in which it occurs during a month. For example, choose to run Scheduled Scan on the second Monday of each month. If you choose the fifth occurrence of a day and it does not exist during a particular month, the scan runs on the fourth occurrence.
