Hi I designed my site using DNN. For the past few weeks my site files getting virus.  It has unwanted codes and Scripts in that. I removed that and I again replaced the cleaned-up files. But it getting that encrypted codes and Scripts again and again. Google webmasters shows that my site should harmfull to open. My site allows the authorized user to enter blog entries. Most of the pages affected are blog entry pages. How can I get rid of it? Please provide any fix and suggest how to prevent from these type hacking?

Thanks in advance.

Hi thanks for your reply.

I am using version 5. I didn't use any third party modules too. I have a strong password.

Thanks in advance.
