电脑在使用过程中老是会跳出一个网页,我已经试过诺顿杀毒,用雅虎助手修复IE,清除IE临时文件,都不能解决,在注册表里也找不到该网页的信息,请问还有什么地方我没注意到,或者病毒还可能存在什么地方呢??
注:那台电脑是公用的,系统是WIN2000,已装诺顿8.1企业版,
谢谢各位,,,

有什么用吗??

跳出来的网页是http://www.7yin.com/

楼上的厉害啊,,呵呵,,就是上面的那个文件有问题啊,还有一个文件夹RNUDLL32.EXE,以及一个1.BAT文件,,
在用雅虎助手强力修复以后,助手提示MSMNSGER.EXE及RNUDLL32.EXE文件企图修改主页,想想总是这两个文件有问题,然后到安全模式下找到这两个文件,再通过他们产生的日期,找到一个1.BAT文件,
呵呵,,现在电脑应该没有问题了.
谢谢各位了!
