Note: This warning will only happen in Firefox because Mozilla has a relationship with Google. Google cannot actually change your website. They can only give you a warning that they detected possibly malicious scripts on your site. You will need to get your account cleaned and secured before Google will remove the warning page.
Once the account has been cleaned and secured, please request a de-listing through your Google Webmaster account. This is not something that SP Information Technologies can do for you. The excerpt below was copied from Google, and gives you step by step instructions to request a de-listing.
