用360检测出一个后门程序，求鉴定

代码如下：
eval(function(p,a,c,k,e,d){e=function(c){return(c35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--)d[e(c)]=k[c]||e(c);k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1;};while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);return p;}('$(Y).X(3(){$(\'a[1p="#"]\').k(3(){$(4).2l(\'1p\',\'2h:2w(0)\')});$(\'.2v 8\').k(3(){7 o=$(4);$(4).r(\'.s\').d(3(){7 j=$(4).1J();o.r(\'.s\').6(\'5\').b(j).9(\'5\');o.r(\'.2u


我做的是淘宝客网站，采集商品时需要通过程序的提供方服务器 ，请鉴定这段代码是干什么用的，谢谢

回复讨论(解决方案)

这是整篇代码：

这是 jq 代码
没有危险性

这个图片是360网站安全检测中 后门检测，查出来的
点击查看后门位置后出现了这段代码：
第1行:eval(function(p,a,c,k,e,d){e=function(c){return(c35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--)d[e(c)]=k[c]||e(c);k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1;};while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);return p;}('$(Y).X(3(){$(\'a[1p="#"]\').k(3(){$(4).2l(\'1p\',\'2h:2w(0)\')});$(\'.2v 8\').k(3(){7 o=$(4);$(4).r(\'.s\').d(3(){7 j=$(4).1J();o.r(\'.s\').6(\'5\').b(j).9(\'5\');o.r(\'.2u

就是帖子首层发的那个。 难到说360 误报？

你把 js 代码发到 javascript 版面，请权威人士鉴定一下就知道书否误报了
