Configuring virus scanning services
This tab also allows you to view the current virus scanner engine version. To
configure the Scanner Advanced tab, follow the steps below.
1 To configure the number of scanner processes for a particular group,
highlight the group in the table and click Modify. The Edit Scanners window
appears. See “About the Edit Scanners window” on page 71 for information
on configuring the number of scanner processes for a group.
2 In the Scan Buffer Size field, specify the size of information (in kB) that can
be held in the memory buffer before a backup file is created to temporarily
hold the traffic for processing. This value must be between 8kB and 64kB.
The default value is 50kB.
3 In the Archive Scan Buffer Size field, specify the amount of memory that
will be used to contain the contents of archive files before the anti-virus
engine will temporarily write the contents to disk to perform the virus scan.
The default is 128 MB.
4 In the Maximum Number of Files to Scan in an Archive field, specify the
maximum number of files that will be scanned within an archive (such as a
.zip file, etc.). If the number of files in an archive exceeds the number
specified in this field, scanning will not take place.
5 To view the virus scanner engine version number that is currently installed,
click Show Installed Engine Version Number Now. A pop-up window
appears displaying the current version. To close the pop-up window, click
OK.
6 To continue configuring the scanner feature, click the Signatures tab and
see “About the Scanner Signature tab” on page 71.
About the Edit Scanners window
The Edit Scanners window allows you to specify the number of scanner
processes that will be available for processing traffic that falls within the size
limits of the selected group. You must dedicate at least one scanner process to
each group.
1 In the Scanners field, specify the number of scanner processes you want to
dedicate for the selected group. The number of scanner processes should
not exceed a combined total of 20 processes for all groups that are
configured. (Configuring more than 20 total processes may have a negative
impact on performance.)
2 Click OK to update the group and return to the Scanner Advanced tab.
About the Scanner Signature tab
This tab allows you to configure the properties for anti-virus updates. The
Sidewinder G2 will automatically download and install updates at intervals that
you determine. You can also manually download and install updates at any
time. Follow the steps below.
