Help!!! Network does not work any more

I installed the Internet Security. The network connection is on and it can passed the any test but just can’t access any website and msn messenger. Why? Even uninstallation won’t work.

Hello feifangongzi,

you must explain these problems in details, please. Have you installed Comodo Secure DNS (check your LAN settings, primary and secondary DNS servers)? Have you got your own trusted network (Network Security Policy’s 3rd tab)? Does the simple PING working for you (e.g. “cmd /k ping”, have you got answer?)?
What are you experiencing when you are trying to uninstall CIS?
