在linux中我们可以使用命令来搜查木马文件,到代码安装目录执行下面命令
代码如下
find ./ -iname "*.php" | xargs grep -H -n "eval(base64_decode"
搜出来接近100条结果,这个结果列表很重要,木马都在里面,要一个一个文件打开验证是否是木马,如果是,马上删除掉
最后找到10个木马文件,存放在各种目录,都是php webshell,功能很齐全,用base64编码
如果你在windows中查找目录直接使用windows文件搜索就可以了,可以搜索eval或最近修改文件,然后如果是dedecms我们要查看最新dedecms漏洞呀然后修补。
下面给个php木马查找工具,直接放到你站点根目录
代码如下

是卡巴斯基的误报,已经解诀了,我也是一样,进入安全模式搞了很久都没有搞定,后来手动更新卡巴斯基的病毒库后就好了。
下面是有关此事的通知:
5月19日 下午 15点20分,CNZZ方面收到卡巴斯基中国公司最新更新病毒库通知,对方已经解决了对CNZZ统计的误报问题,CNZZ统计服务目前已在第一时间恢复正常。如果部分用户仍然报毒,请手动更新卡巴斯基病毒库。
一般情况下,电脑中毒或者中木马或者病毒之后,木马病毒都会破坏系统的,一般杀毒软件是不能解决这些问题的,推荐你使用金山网盾或者金山急救箱等系统修复工具对系统进行修复,我就是这样解决问题的。
建议你最佳解决方案
第一步:下载金山毒霸2011【百度搜索 金山毒霸】 选择官方下载
第二步 安装完以后,打开金山毒霸,点击“全盘查杀”
