我的电脑每次开机都会有这个，为什么？怎么解决啊？ 谢谢

检查下你自己的启动项。这是由启动项或者ruandll32加载不存在dll造成的，你可以使用某些优化工具进行清理，如果还不行的话，可以自己手动清除，不过有一定的风险。
在运行里输入regedit，接着按照这个路径找
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
找到run的时候，双击它，看到右边有几个选项，你自己去看看哪个是baidubar的，根据你的给我看的图片，一般来说，可以在数据（value）那个列里发现某些行有这个关键字 rundll32，还是rundll或者是run我还真忘记了，（有些也是调用那些的，别删错了）准确无误的找到了就把它删除了，如果你发现不能删除，或者删除了等于没有删除，那么你检查下你自己的杀毒软件。你自己认真看看。
那是因为你卸载或者是安装baidubar的时候出错，你可以下载一个window优化大师，进行系统的优化清理，然后重启一下，就OK了、
这个不是什么大问题，只要你平时使用的时候系统不出什么问题就行；
如果你对系统有了解，最好使用一些软件进行注册表优化，然后优化开机启动项，这些问题就可以解决了。推荐使用360安全卫士进行优化！
安装非正版的Win7系统出现这样的问题较多；其次就是你没有得到管理员的权限（办公电脑）；
再就是中毒；最后就是杀毒软件禁止了你访问（360杀毒较常见此情况）。
建议：
1.重装系统；
2.向管理员要权限；
3.用安全模式先查毒，后试QQ登录；
4.在杀毒软件里设置白名单（需要确定未被病毒感染）。
这是败毒的一个工具条。删除文件或许没有删除干净。建议在注册表中清理一下。
