My problem is about Kaspersky Antivirus Software

Hello,
My problem is about Kaspersky Antivirus Software. Recently I have installed that in my pc. I have used original CD, license key. But when it tries to update, the error message displays as “updating Kaspersky Rescue Disk image (could not download Kaspersky Rescue Disk database from the Internet.
Probably either network connection may be missed or there is low space on hard drive). Solutions available, do you want to continue without update?”
This message is shown every time.
Help me please.
