more scans increases the amount of memory and CPU resources required by the
antivirus scanning.
Click Submit.
Storage
It is recommended that you use a network or local share to provide storage for the virus
database and temporary space for the scanning process. This greatly increases the
effectiveness of the antivirus scanner.
Network storage
A network share is a shared folder or drive on a local Windows PC, or a PC running
another operating system capable of SMB sharing (such as Mac OS X, or a Linux PC
running the SAMBA service).
Refer to your operating system’s documentation for details on creating a network share.
What follows are some basic instructions for creating a network share under Windows
XP.
• Create a new user account:
Note
We recommend that you create a special user account to be used by the CyberGuard
SG appliance for reading and writing to the network share. If you have an existing
account or wish to may the network share readable and writeable by everyone, you
may skip the next step.
