　　QQexternal.exe是腾讯为QQ特别定义的一个QQ外部应用相关程序，在我们安装了腾讯QQ并启动它的时候才会运行QQexternal.exe，如果我们关闭了腾讯QQ，那么QQexternal.exe进程也随之关闭，现在问题来了，QQexternal.exe是什么进程呢？

　　在QQ2011及其以后版本里面的QQExternal.exe是外部应用相关进程，而在QQ2008版本之前的QQExternal.exe是广告相关进程。

　　QQexternal.exe对系统有什么影响？

　　在一般情况下，一个只有50K的QQexternal.exe基本上是不占用系统内存资源和CPU资源的。但凡事都有例外，当你发现打开QQ之后电脑就变得无比卡，那你就得看看QQexternal.exe究竟在干啥了！

　　以笔者的电脑为例，一个50K的QQexternal.exe竟然长期占用31M内存左右，长期占用6%的CPU资源，要知道，QQ2012的主程序也才占用1-2%的CPU资源，31M左右的内存。因此笔者想再次请问腾讯客服，这是什么概念？

　　在最极端的时候，笔者曾经发现这个QQexternal.exe竟然占用了31%的CPU资源！

　　删掉QQexternal.exe对QQ有什么影响？

　　经过笔者测试，在QQ2012里删掉这个在笔者电脑上无时无刻占用部分系统资源的QQexternal.exe竟然对QQ的稳定性和系统没有任何影响，反正笔者删掉QQexternal.exe这个文件之后已经使用QQ2012数个月了，至今没有看到一次系统蓝屏或者QQ崩溃。倒是 QQexternal.exe存在的时候，笔者的电脑就莫名其妙地卡机，重装系统N次也是一样。

　　因此说，删掉QQ2012的QQexternal.exe，对系统和QQ都没有任何影响。如果删掉QQexternal.exe之后出现问题，请重新安装QQ即可。

　　笔者在此强调一下，不能删除QQ2013里的QQexternal.exe文件，否则会导致登录QQ失败。

　　怎么删掉QQexternal.exe？

　　删掉QQexternal.exe的方法非常多，最简单的一种就是直接搜索这个文件再干掉。以下的举例是如何删掉QQexternal.exe的常用方法之一。

　　第一步，在Win7里按“Ctrl+Shift+Esc ”快速打开任务管理器（XP的快捷键为Ctrl+Alt+Delete），然后在进程那里找到QQexternal.exe后点击右键选择“打开文件位置”；

　　第二步，直接删掉QQexternal.exe。




　　有时候电脑运行了腾讯QQ，但是打开任务管理器不一定能够看到QQexternal.exe进程，不过如果在打开QQ后电脑变卡了，那么QQexternal.exe是很值得怀疑的对象。对于是否要删除QQexternal.exe由用户决定，因为QQexternal.exe不一定会大量占用系统资源。
