My site blocked by Avast

So my site is getting blocked by Avast and it seems only antivirus that does that.I tried opening it with several different antivirus programs and on other computers where everything works fine.Considering that,is it perhaps a fake alert?

It says its Trojan Horse,and some clients were complaining they can’t open site and they had Avast too.Site is . Sorry for my bad English

Hi,

If you believe it is a false positive, you can report the issue to avast! here: http://www.avast.com/contact-form.php?loadStyles
