Thank you for the reply, but no such file exists in that folder of mine.
.conf is always in:
X:\Users\XXXXX\AppData\Roaming\XXX
-> X:\Users\XXXXX\AppData\Roaming\Clam
You are welcome.
You have just to create a file named:
clam.conf
and insert it.
Be aware that the name is clam.conf and not clam.conf.txt
