Since around 2 weeks I get a virus warning from my provider.
Until now I have ignored it.

Have looked a little bit more in the detail:
My provider scan the traffic in general. If there is detected traffic which includes 'bad' content such a message is send to the user-side.

I'm not sure if really is somewhat on the server side.
I have quite often open the site to 'http://wsprnet.org/drupal/wsprnet/map' where this message is comming up - and only here.
Info of the provider is only it is malware related to Candc [Command and Control Server (C&Cs]
Not more detailed info.

Maybe other users are having equal experiences ?
