[. . . ] Restart the program to change the SAVAPI. DLL. Avira GmbH AntiVir ISA Server 23 Configuration 5. 2. 1 Entries in SAVAPI. INI You can change the following parameters in the configuration file SAVAPI. INI: Port Number This indicates the TCP/IP port for the communication between AntiVir ISA service and SAVAPI. DLL . If this port is already assigned, you can change the value. Remember to modify the corresponding entry in SAVAPIDL. INI (see Entry in SAVAPIDL. INI (optional) ­ Page 29). Example PortNumber=18371 Update Directory In this directory, AntiVir ISA service temporarily saves the updates downloaded from the Internet. It is a so-called working directory for the Internet Updater and it should not be changed. Make sure AntiVir ISA update service has write access to this directory. Example UpdateDirectory=C:\Programs\AntiVir\AntiVir ISA Server\update\ Name of the License File This parameter refers to the license file name which has been copied to the installation directory. Example KeyFileName=C:\Programs\AntiVir\AntiVir ISA Server\ hbedv. key Name of the Logfile It specifies the name of the logfile. You can move the logfile to another location on your hard disk. AntiVir ISA service needs write access for this location. By default, the logfile is placed in the installation directory and it is named SAVAPI. LOG. Example LogFileName=C:\Programs\AntiVir\AntiVir ISA Server\ savapi. log Maximum Logfile Size This value is the maximum size of the logfile (in kB). When the file size exceeds the limit, the oldest entries are deleted automatically. The file has no size limit if the value is 0. Example LogFileSize=1000 24 AntiVir ISA Server Avira GmbH Configuration Scan Archive If the value is 1 (activated), AntiVir ISA service also scans for malware in archives. The parameter is "deactivated" (0) by default. Example ScanArchives=0 Maximum Recursion for Archive Scanning This value sets the maximum nesting level for scanned archives. AntiVir ISA service unpacks the archived files down to this level and scans them for viruses and other types of malware. Usually, the default value (2) is sufficient. The parameter applies only when ScanArchives is active. Example ArchiveMaxRecursion=2 Automatic Archive Detection Archives can be identified in two modes: based on the file extension or on the contents. The detection based on the contents ("SmartDetection") is a safer method, but it takes longer. If this option is active (1), AntiVir ISA service tries to identify the archives by means of content; otherwise by file extension. The parameter applies only when ScanArchives is active. Example ArchiveSmartDetection=1 Blocking "mail bombs" It blocks so-called "mail bombs" with a very high compression ratio. You can specify up to which ratio AntiVir should unpack archives, between archived and unpacked file size. The value 0 deactivates this option, but it is not recommended. The default is 150. Example ArchiveMaxRatio=150 Maximum Size of Unpacked Files There are compressed folders which do not contain any significant information but which are intentionally created to expand to an "absurd size" and to slow down the computer. This parameter avoids unpacking such archives. If the value is 0 Bytes, all files are unpacked, irrespective of their size. [. . . ] These can be interferences such as viruses or other software, which the user generally considers as unwanted (see also Unwanted Programs). Logfile Malware PMS (Possible Malicious Software that does not usually harm the computer. It is programmed to Software) harm other users. For example, mail bombs: with such a program, the victim can be attacked by thousands of emails. AntiVir detects PMS (Unwanted programs configuration tab). [. . . ]
