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 agent 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.
