Adding new clamav databases clusing this error when I testing ClamWin's bundled clamscan:

Is this build in limitation for memory allocation? As far as I checked the configuration file, I didn't find such configuration.

I used this command:
C:\Program Files\ClamWin\bin>clamscan.exe -d "C:\Documents and Settings\All Users.clamwin\db"

clamscan.exe --version
ClamAV 0.103.2

freshclam --version
