????? 日前多数使用卡巴斯基杀毒软件的网友在浏览百度旗下众多网站时均出现了木马病毒警报。如下图：

????? 该JS文件内容如下：
function cf(flashsrc,flashwidth,flashheight,flashlink,br){
?document.write(“<table width=”+flashwidth+” height=”+flashheight+” border=0 cellpadding=0 cellspacing=0><tr><td>”);
?document.write(“<div style=\”position:relative\”>”);
?document.write(“<embed style=\”position:absolute;z-index:0\” src=”+flashsrc+” quality=\”high\” width=”+flashwidth+” height=”+flashheight+” TYPE=\”application/x-shockwave-flash\” PLUGINSPAGE=\”http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash\” wmode=\”opaque\”></embed>”);
?document.write(“<div style=\”background:white;filter:alpha(opacity=0);opacity:0;position: relative;z-index:10;left:0pt;top:0pt;width:”+flashwidth+”;height:”+flashheight+”px;\”>”);
?document.write(“<a href=”+flashlink+” target=\”_blank\” style=\”cursor:pointer;display:block;width:”+flashwidth+”;height:”+flashheight+”px;\”></a>”);
?document.write(“</div>”);
?document.write(“</div>”);
?document.write(“</td></tr></table>”);
?if (br==”1″) {
?document.write(“<br>”);
?}
}

function cf1(flashsrc,flashwidth,flashheight,br){
?document.write(“<embed src=\”"+flashsrc+”\” quality=high pluginspage=\”http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash\” type=\”application/x-shockwave-flash\” width=”+flashwidth+” height=”+flashheight+” align=center wmode=\”opaque\”></embed>”);
?if (br==”1″) {
?document.write(“<br><br>”);
?}
}

????? 可以看出该文件并没有什么明显异常，且还没有出现其他杀毒软件报警的情况（我使用诺顿安全特警2009），所以误报的可能性比较大。
