My website contains dangerous code!

Hi all,

Recently my website has been rejected from two advertising networks. The reasons?

Ad network 1: "Unfortunately we are unable to approve your site because it has a permanent redirect to another site. Let us know when you remove dangerous html code from your site we will review it again.". I asked then for a better explanation and they sent me the following screenshot .


Ad network 2: Site denounced as dangerous by Antivirus ESET NOD32

From all this I could conclude my website is not standing in a good position.

I have checked my website with this tool http://www.internetofficer.com/seo-tool/redirect-check/ and it confirms the domain has no redirection.

I have downloaded McAffe Internet Security Site Advisor (pain in the *ss) and could visit my website without warnings whatsoever.


Website info: Joomla 1.5 based, with several plugins and components installed.

Any advice? What to do? How do I know what is the code that is causing this issue?

THANKS!

 

Maybe your site has a minor trace of malicious code.

You are using Joomla 1.5 which has many security vulnerabilities. The Joomla community has asked everyone to upgrade for security and support reasons. You site may have been attacked. If there is any malicious code I would be able to remove it as well as upgrade your website to the latest version of Joomla.
