I use one computer that MUST be out of any net (internet too). So i try to install ClamWin to this computer... but I can't use it? because the installation doesn't contain a virus database...

Why don't you try to add function for this... you have no internet access... so show download virus database form this .... url and run/execute/install this downloaded package soon on your computer

Hello
You can get the virus definitions without clamwin via https://
https://database.clamav.net/main.cvd https://database.clamav.net/daily.cvd
Then copy the downloaded main.cvd and daily.cvd to your database location which is specified in the ClamWin Preferences, File Locations tab. The default database location is: "C:\Documents and Settings\All Users\.clamwin\db"
