[clamav-users] How to trick clamav

[doark at mail.com]

Hello,
I have two computers, a laptop (for getting online stuff), and a desktop.
The desktop is at home which has no internet access due to the fact that
I live in a rural area.
I transferred the /var/lib/clamav/ (cvd) files to the desktop but the
clamav on the desktop will not accept them, what do I do?
The actual error message and related details are as follows:

/********************************************************************/
