See the attached file...

I was looking into the dump, but understand nothing...
...except, that if I go to the DNS

    http://static.88-198-17-100.clients.your-server.de/

I am redirected to

    http://www.julispace.com/

And realy, I do not like unknown connections to private servers...
I do not understand, WHY clamav is connecting to this server...

Thanks, Greetings and nice Day/Evening
