Hi all,

Two days ago, Google show this warning on my site: "This site may harm your computer" but I really don't distribute any malware, virus or any thing like that. This thing decrease my traffic seriously.

Here is information from Google Safe Browsing:

My site was hosted in GoDaddy hosting.

How can I solve this problem?

Thanks in advance.
