This section explains the steps required to configure scanning for compressed files for Real-time, Manual, and Scheduled Security Risk Scan.
To optimize scanning performance when scanning compressed files, clear Do not clean infected compressed files to optimize performance on the Security Risk Scan > Action tab.
On the left menu, click Security Risk Scan and select the Target tab.
From the Target tab, under Advanced Options, expand Scan Restrictions Criteria.
Select the checkbox for the items you want to scan and set the appropriate values.
Under Do not scan file if...
File size exceeds—type a value between 1-30-MB.
Under Do not scan compressed files if, type values according to the following:
Decompressed file count exceeds [xxxxx]—type the total decompressed file count (1-10000) that should not be exceeded. When PortalProtect encounters a number of files equal to or greater than this number it will not scan the files.
Size of Decompressed file exceeds [xxxx]—type a value in megabytes (1-2048) to set a limit for the size of the compressed files PortalProtect will scan. When PortalProtect encounters a compressed file that is equal to or greater than this size, it will not scan the file.
Number of layers of compression exceeds [xx]—type a number (1-20) to set a limit for the number of layers of compression to which PortalProtect will scan. When PortalProtect encounters a file of a compression layer equal to or greater than this number it will not scan the files.
Size of decompressed file is "x" times the size of compressed file—decompressed files must not exceed the multiple entered according to the compressed file size. Type a multiple (100-1000000) that the decompressed file must not exceed. Decompressed files that exceed the value: decompressed size is "x" times larger than the compressed size, will not be scanned.
Click Save.
Office 2007 files are compressed files. If an office 2007 file exceeds the scan restriction criteria, PortalProtect will treat it as an unscannable file.
