trouble with a private page

Hello mebers of Avast staff:
My name is Johnattan, and I work in a private corporation in Colombia country (Connexion movil). Me and my job team are working in development (Ekzpert), we have a page where that is a private development for to optimize any process for a transport system.
I’m posting you cos when the users try to get in the page (“connexionmovil.ekzpert.com”), if the pc of his user have that avast antivirus, dont let you get in.
That is a trouble beacouse the user must desactivate this antivirus. for to let input in that page. That is not the idea. But I have tried many things, all within sucess.
This page, when i and my team are working have a hard code. This use php code, apis of google, jframes for jaspersoft, Jquerys and all that are using an struct MVC with framework Zend.
I dont know if u have any idea for help tome and my team Ekzpert. But i had not find the problem. My last resourse u are .
If u request any thing for help me, is not problem, i will pass u that u need.
thanks for your time.
I’ll be looking forward.
thanks

PD: the pages are copies for different corporations.

I am not an avast! staff member, but I have third party scanned your site from front to back and here is my report:

When you think the site has got a FP detection, report here: www.avast.com/contact-form.php‎

What could have been a reason for blocking is
NS ciudadmovil.com.co NS target:ns2.afraid.org
IN 3600
ciudadmovil.com.co NS target:ns4.afraid.org
IN 3600
ciudadmovil.com.co NS target:ns1.afraid.org
IN 3600
ciudadmovil.com.co NS target:ns3.afraid.org

This could have been a valid reason for an avast team member to add sites to blocking, changing from afraid dot org could be a reason to unblock…

IP is blacklisted here http://www.apews.org/?

CASE: C-684 AS14080 CO, [b]ISP permits abuse and/or ignores criminal activity[/b]

Yep, Pondus, thank you very much for confirming this detection.
This is exactly the problem - being with afraid dot org - and also the reason that avast! blocks that site.
avast! team member, Milos explained this issue in a couple of his reactions to apparent FP reports.
See below:
DNS Check results;
Delegation: Domain connexionmovil dot ekzpert dot com/IN does not exist.
Search for Parent for connexionmovil dot ekzpert dot com failed
Delegation not found at Parent. Link to this test: http://dnscheck.sidn.nl/?time=1392474829&id=1735990&view=basic&test=standard
And the guys at APEWS.ORG also must have these results.
