我的电脑每次开机我用瑞星查杀内存时都会有清除了iexplore.exe的提示,想问问iexplore.exe到底是什么病毒,为什么开机就又出现了总也杀不死,非常感谢!!

这不好说，你在开机时上网了吗？有没有打开iexplore.exe？
现在好多木马都是插入到系统正常进程中，来穿墙的。你最好从http://forum.ikaka.com/topic.asp?board=28&artid=6979213
下载System Repair Engineer 2.0.21.505（RC2）导出全部日志,不要修改，贴上。

我的电脑里面也有这个东西

在进程里先结束IEXPLORE.EXE然后到网上找相关的杀毒工具
iexplore.exe是Microsoft Internet Explorer的主程序。这个微软Windows应用程序让你在网上冲浪，和访问本地Interanet网络。这不是纯粹的系统程序，但是如果终止它，可能会导致不可知的问题。iexplore.exe同时也是Avant网络浏览器的一部分，这是一个免费的基于Internet Explorer的浏览器。注意iexplore.exe也有可能是Trojan.KillAV.B病毒，该病毒会终止你的反病毒软件，和一些Windows系统工具，该进程的安全等级是建议删除
这个东西可以说是病毒，也可以说不是病毒。
因为微软的浏览器就是IEXPLORE.EXE，但是它一般情况随系统被安装在C:\Program Files\Internet Explorer下面。那么，如果发现这个文件是在这个目录下面的，一般情况不是病毒，当然，不包括已经被感染了的情况；还有一种情况，就是IEXPLORE.EXE在C:\WINDOWS\system32\下面，那么这个十有八九都是病毒。

iexplore.exe进程－－病毒

系统进程－－伪装的病毒 iexplore.exe
Trojan.PowerSpider.ac 破坏方法：密码解霸V8.10。又称“密码结巴”
偷用户各种密码，包含：游戏密码、局域网密码、腾讯QQ账号和密码、POP3 密码、Win9x缓存密码及拨号账号等等。这个木马所偷密码的范围很广，对广大互联网用户的潜在威胁也巨大。


现象：
1。系统进程中有iexplore.exe运行，注意，是小写字母
2。搜索该程序iexplore.exe,不是位于C盘下的PROGRAMME文件夹，而是WINDOWS32文件夹。



解决办法：
1。到C:\\WINDOWS\\system32下找到ixplore.exe 和 psinthk.dll 完全删除之。
2。到注册表中，找到HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion
\\Run “mssysint”= iexplore.exe,删除其键值

不一定是Trojan.PowerSpider.ac，还是贴日志先！

我同意楼上的意见！

附日志如下,除了瑞星提示开机以后清除iexplore.exe以外,最近系统运行的也有问题,慢多了,在此一并对帮忙的朋友表示感谢!
