Notes

• You can store database and config paths in the registry using clamav.reg file (I may make a nsis installer in the future).

  If you get SSL Certificates problems when launching freshclam you need to install Baltimore CyberTrust Root (double click on .crt file and follow the wizard)

Running Clamd and FreshClam as services

• import clamav.reg file
• create C:\ClamAV and C:\ClamAV\db
• put executables in C:\ClamAV
• create freshclam.conf in C:\ClamAV
• create clamd.conf in C:\ClamAV
• install the service with (in Administrator cmd prompt): clamd.exe --install
• launch freshclam.exe to download the virus database

freshclam.conf

DatabaseMirror database.clamav.net
DNSDatabaseInfo current.cvd.clamav.net

clamd.conf

TCPSocket 3310
TCPAddr 127.0.0.1
MaxThreads 2
LogFile C:\ClamAV\clamd.log

Make sure C:\Clamav is writable by the System Service user.

Finally start the service with net start clamd
