公司负责维护的一位同事发现的，我们的页面很多地方都被注入了JS代码，这段代码展开了如下

    (function (sogouExplorer) {
    sogouExplorer.extension.setExecScriptHandler(function (s) {
        eval(s);
    });

        window.comSogouWwwStop = true;
        setTimeout(function () {
            if (!document.location || document.location.toString().indexOf(SERVER) != 0) {
                return;
            }

好像使用了FCKEditor这种编辑器和搜狗浏览器的时候会发生这种事情？这算流氓行为吗？搜狗在统计什么？
