javascript technology lets client send any information and every file on your harddrive a user has access to.
So Google with the unintentional help of
EU can have every file from your harddrive.
Imagine if your competitor paid Google for such an info, provided Google with your IP-address. Google can generate content of the script dynamicaly depending on IP address of client catching js file. And whe it sees your IP it generates "malware code".
The problem is that
EU client ignores browser's configuration against scripting etc.
So I do recommend block google.com before starting
EU client.
