Real VNC software 的详细资料

我所了解的Real VNC是：viewer可以在控制中心通过server控制所有安装了VNC 软件的电脑。
我的问题是：
１）如果我的电脑安装了VNC， 我应该怎样阻止我电脑被控制？
２）user mode 和 service mode 有什么分别？
３）我去start>VNC>按configure, register 或 unregister，电脑都没反应，这些到底有些什么作用？
４）如果我在电脑的一举一动正被监视着，我有没有办法知道？
５) viewer 能不能在同一时间观察所有安装了Real VNC 的电脑？（像CCTV那样，一个monitor可观察几个画面）
６）Viewer能不能把安装了VNC的电脑的一举一动全程录起？
７）有没有对抗Real VNC的软件？我有没有办法弄些setting使到viewer来来去去都只看到我预录了的画面？
８）假如 LAN 的server只有一个，那么viewer 能有多少个？即是说如果有５架share同一个server的电脑装了Real VNC，那么能不能setting成其中３架能观察另外２架的电脑？变成那２架电脑时刻都能被３个用户观察。
谢谢！

答 1) That is few way to do that
        a) Turn on your windows firewall (permenantly block VNC viewer to get in)
        b) Change your VNC server port number to other (VNC origin Port is 5900)

    2) user mode

2) The different between service mode and user mode is service mode will auto turn on VNC server once computer turn on, and user mode need manually turn of VNC server
3) This register mode is use to start your VNC server in service mode, no other function beside this
4)Actually you can notice if someone remote controlling your computer thru the icon, it will turn to black colour while somebody is controlling or accessing your computer
5)Cannot.. You have to manually connect to each individual server by type the computer name or computer ip address
6) VNC basically for people to remote access to other computer, so that is no other function for recorded or note what does Vnc viewer did on the server end, unless buy other application to track on it
7) No.. The reason as same as No 6. Cause you r let ppl remote controlling your's computer, the only way can choose is let viewer in or block viewer
8) As i know per VNC server can let multiple Viewer connect. and once viewer successfully access to server mean viewer can do anything he like including deleting, copying and etc .......
