环境多样性原理:为什么会这样呢，QQ被盗

今天我上QQ，一上来就看到有人发信息，我点开的时候还没看到是谁发的，QQ就掉了。提示是：重启程序/QQ遇到问题需要重启。
错误信息是：
Microsoft Windows 2000 Service Pack 4 [Build 5.0.2195]

QQ 15.63.310 C9C851904396CBF34E827203B4900465

不知道是怎么回事，再上去我的密码就被盗了。于是我很快的去取回密码。密码是取回了。但下次我再上的时候，发现又有人给我发信息，还是我的一个好友，我就打开了。出现了和上次一样的情况。这次密码没被盗。我还可以上去。但点开其中一个好友的资料看的时候QQ就会重启，点别人的都不会。
我问别人，有人说也许是我的电脑成了肉鸡什么的？
谁知道是怎么回事呢？？

我会追加分的。
