学习笔记之有关杀毒软件对软件运行的影响

最近刚换了百度 杀毒软件

结果杀毒软件影响jsp的编译，把eclipse、tomcat、操作系统都重做了，最终发现是杀毒软件的问题。

真是，原来做技术支持 的时候不经常因为杀毒软件造成 各种错误嘛，怎么现在却忘了呢，最后到了重做操作系统的境地....

是啊，仔细想想只要是一些系统比较底层的软件都可能对其他软件的运行会造成影响，比如杀毒类，管家卫士类，还有输入法（没错，国产的输入法）等等。

另外每次重装完系统后user文件夹和program files文件夹最好自己吧有用的东西有选择性的拿出来，不要直接去覆盖，可能会出问题。

把相关软件加入白名单之后问题解决。

看上去杀毒软件还是慎用，慎换，不然出现莫名其妙的问题都不知道是怎么回事。

记下这个教训。
