Eset Nod 32 found a virus on my wordpress site

Every time when a visitor with Nod 32 visits my site it says that my website is infected with HTML/ScrInject.B.Gen virus

I scanned it with sucuri(dot)net and it says:

Anomaly behavior detected (possible malware).
Details: http://sucuri.net/malware/malware-entry-mwanomalysp8
<script type="text/javascript" src="http://analytics.hosting24.com/count.php"></script>

That is the analyics code from my 000webhost, and I disabled that code. The malware was found on my "about us" page. Anyway I see some activity on my "about us" page. My analytics says that is a unknown spider with ip 118.70.127.134 and Hostname: mail4.bkav.com.vn clicking like this:

07:58:16 ->/about-us
07:58:17 ->/about-us/
07:58:19 ->/about-us
07:58:20 ->/about-us/

I installed some security plugins and anti-virus plugin for wordpress.
Please, there is somebody to help me on how to remove this? I don't want to lose visitors and rankings

Can someone help me to get rid of that nod32 notification?

Ok, so there is somebody who know how to get rid of malware?

Looks like you have some code in your wordpress, or some body has installed some code.

Can you check your blog, whether it is connecting to any url?

Because usually i see virus in ecommerce, wordpress is very low cases.

How can I check if it's connected with with other URLs?

I think it's the analytics code from 000webhost, but i disable it. but it's still on after my last sucuri.net scan.

I only want to have visitors with eset nod32 antivirus on my site again...
