I can't seem to get this to auto update. ClamWin doesn't use a freshclam.conf, it seems, and when I tried it with clamwin.conf, nothing happened. Any idea what to do?

Also, when I applied these manually, the amount of viruses in the signature count didn't change.

Hello Robert,

Running MS-DOS command line shell :
C:\Program Files\ClamWin\bin>sigtool.exe -l --datadir=c:\ProgramData\.clamwin\db\ |findstr Securite

Seems to work. I can see the signatures from SecuriteInfo.com

Did you put the signature files at this exact place : c:\ProgramData\.clamwin\db\
