Hi,
The OVH company hosting, send me a msg about blocking access to my website, cause it’s system detect that there are some thing wrong in one of the scripts who is ‘jetpack’ !!! and maybe a hacker who want to access to my website.

This is the src of problem :

Problème rencontré : Executing deleted program
Commande apparente : ././crond
Exécutable utilisé : /homez.626/educationen/www/wp-content/plugins/jetpack/_inc/fonts/automatticons/.nfs000000000c0b389700000010
Horodatage: 2015-02-05 18:55:06

My web site it’s now off-line

Forbidden
You don't have permission to access / on this server.

So I’d like to know what’s happen with the Jetpack before i contact the OVH team.

Thanks
