Hi ti.colmaster, welcome to the forum
First, this site is blocked by the network shield.
The web shield also alerts on a script inside the site.
It seems as though one of the javesript files on the site are infected. I have looked through and I think that the script in:
is infected. This script is a very long script that appears to be obfuscated, and is suspocious...
I am not completely sure, but this could be the issue. I will have to ask one of the avast! team about this.
EDIT: apologies for the non translation, I have asked someone who knows the language to translate
