最近的一次系统“维护”和更新

笔者开发还比较在行，但对系统的维护和管理几乎一窍不通。

最近系统中病毒，看来这个病毒是挺深入的。用了卡巴，AVG，和一些antimalware工具都没有效果。症状似乎是劫持，修改或注入了系统关键进程（也可能是隐藏的进程，但rootkit检查没有问题；因为从一般的进程管理器上看没有任何可以进程，但它似乎通过explorer.exe并用-embedding选项启动了iexplore；甚至试着挪动iexplore，它找不到iexplore就转而去把services.exe搞大，看来系统已经被毁掉了），也改变了所有浏览器（不管新安装的还是老的，是否IE内核）的上网路径（这可能是改了系统因特网的配置）。可能这些具体问题都能用windows的一些具体修复技巧能解决，但比较懒，而即便如此也不能确定系统安全，而这个Windows 7旗舰版貌似也是有很大先天不足，且经过一番修改折腾EXPLORER和IEXPLORE都已经出了问题，所以就决定删除系统，装Ubuntu Linux（一样是相对来说供懒人用的Linux）。现在想想年初Ubuntu用得挺好，不是为了要上Games Programming课用XNA，是不会把它拆了装玩物丧志的Windows 7。而我向来也不喜欢双系统。

但手头没有光盘，也没有大的U盘（只有128M），但有大的移动硬盘。所有安装Ubuntu要用一些额外的工具，网上介绍不多，但以下这篇关于syslinux的说明非常简便易行：

当然比较繁琐一点的是用GRUB（如WinGrub和Grub4DOS等）修改MBR和配置文件，一篇介绍文字在此。

另外出于好奇也为了以后需要，要将那个损坏的Windows 7备份成虚拟系统，以前对Win XP用过Norton Ghost可以做到，现在发现貌似可以用VMware vCenter Converter。删除一些不必要的程序，把文档资料拖到备份盘，做VM，重启安装Ubuntu，准备开虚拟机，第一个考虑装的是Windows 8 Developer Preview（这样最佳情况下Visual Studio也有了，不过是11; and unfortunately it is not run on VMware player which I can have for free on Linux, still I can wait till some updates come up to support it），就一路和Windows 7暂时说拜拜了。

”这是Windows 2000了，“，十年前表弟erloz说，屏幕上闪着“基于NT技术构建”的字样，”以后不会死机了“（相对于98确实是这样了）。

”这是Linux了，“，现在我说，”以后不会有病毒之忧了“（相对于Windows也确实是这样）。

After a few hours of struggles, I finally managed to install that windows 8 preview in a virtual machine, but it's known that only certain virtual machine applications support this, among them are oracle's (formerly sun) virtual box, VMware workstation 8. And it is sure VMware player (with workstation 8 equivalent engine) doesn't work with that. I'm using virtual box on Ubuntu which is free, and it is the first time I use the software, and I found it's fantastic and running absolutely well. Now I even doubt it outperforms in almost every aspects than VMware for a common personal virtualisation user. And it seems there's no difficulty installing such software as Tortoise SVN on the system and everything preinstalled on it is with its version ticked up by one. So far everything looks perfect and sound.

Generally, Linux applications are still craps; although I am aware of and appreciate the endless and so far successful effort Ubuntu has made to enhance the user experience and the integration of the interface. But there's still a long way to go. Linux does have some good applications to offer now and then. A typical instance of this is the media player set of banshee, movie player and vlc. the last one is extraordinarily excellent and outstands even on a windows platform, while the first two are just rubbish.

Unfortunately, migrating of the damaged windows 7 from physical machine to virtual basically failed; it did try to automatically fix the problem which is caused by the differences in running environment it has detected, however it never came through the process and ran into an irreversible state where there's no chance to fix it any more.
