scanexc
Configure scan exclusions to increase the scanning performance and skip scanning files causing false alarms. When a particular scan type runs, OfficeScan checks the scan exclusion list to determine which files on the computer will be excluded from both virus/malware and spyware/grayware scanning.
When you enable scan exclusion, OfficeScan will not scan a file under the following conditions:
The file is found under a specific directory.
The file name matches any of the names in the exclusion list.
The file extension matches any of the extensions in the exclusion list.
Scan exclusion lists for files and directories support the use of wildcard characters. Use "?" character to replace one character and "*" to replace several characters.
Use wildcard characters cautiously. Using the wrong character might exclude incorrect files or directories. For example, C:\* would exclude the entire C:\ drive.

OfficeScan will not scan all files found under a specific directory on the computer. You can specify a maximum of 250 directories.
You can also choose Exclude directories where Trend Micro products are installed. If you select this option, OfficeScan automatically excludes the directories of the following Trend Micro products from scanning:
ScanMail™ for Microsoft Exchange (all versions except version 7). If you use version 7, add the following folders to the exclusion list:
\Smex\Temp
\Smex\Storage
\Smex\ShareResPool
ScanMail eManager™ 3.11, 5.1, 5.11, 5.12
ScanMail for Lotus Notes™ eManager NT
InterScan™ Messaging Security Suite
InterScan Web Security Suite
InterScan Web Protect
InterScan VirusWall 3.53
InterScan FTP VirusWall
InterScan Web VirusWall
InterScan E-mail VirusWall
InterScan NSAPI Plug-in
InterScan eManager 3.5x
If you have a Trend Micro product NOT included in the list, add the product directories to the scan exclusion list.
Also configure OfficeScan to exclude Microsoft Exchange 2000/2003 directories by going to Networked Computers > Global Client Settings > Scan Settings. If you use Microsoft Exchange 2007 or later, manually add the directory to the scan exclusion list. Refer to the following site for scan exclusion details:

When you configure the file list, choose from the following options:
Retains client computer's exclusion list: This is the default selection. If you make changes to the exclusion list and this option is enabled, you will not be able to save the changes. This option is provided to prevent overwriting a client’s existing exclusion list accidentally. If you want to deploy the changes you made, select any of the other options.
Overwrites the client computer's exclusion list: This option removes the entire exclusion list on the client and replaces it with the list you just configured. If you choose this option, OfficeScan displays a warning. To proceed, you must click OK in the message window.
Adds path to the client computer's exclusion list: This option adds the items in the list you just configured to the client’s existing exclusion list. If an item already exists in the client’s exclusion list, the client ignores the item.
Removes path from the client computer's exclusion list: The client removes an item in its exclusion list if it matches an item in the list you just configured.
OfficeScan will not scan a file if its file name matches any of the names included in this exclusion list. If you want to exclude a file found under a specific location on the computer, include the file path, such as C:\Temp\sample.jpg.
You can specify a maximum of 250 files.

OfficeScan will not scan a file if its file extension matches any of the extensions included in this exclusion list. You can specify a maximum of 250 file extensions. A period (.) is not required before the extension.
For Real-time Scan, use an asterisk (*) as a wildcard character when specifying extensions. For example, if you do not want to scan all files with extensions starting with D, such as DOC, DOT or DAT, type D*.
For Manual Scan, Scheduled Scan, and Scan Now, use a question mark (?) or asterisk (*) as a wildcard character.
OfficeScan allows you to configure scan exclusion settings for a particular scan type and then apply the same settings to all the other scan types. For example:
On January 1, OfficeScan administrator Chris found out that there are a large number of JPG files on client computers and realized that these files do not pose any security threat. Chris added JPG in the file exclusion list for Manual Scan and then applied this setting to all scan types. Real-time Scan, Scan Now, and Scheduled Scan are now set to skip scanning .jpg files.
A week later, Chris removed JPG from the exclusion list for Real-time Scan but did not apply scan exclusion settings to all scan types. JPG files will now be scanned but only during Real-time Scan.
