Sorry if there is some similar threads. The problem is: I tried a program and found it started outbounding traffic. I uninstalled the application and blocked the traffic. Then I found it still in the application list in jetico. More funny, I found firefox and IE not working. It turns out that firefox and IE tries to launch that app to access internet. I have to restart the computer, everything goes ok again. Just wonder what happened. As I remember the xdict caused the similar problem on my laptop before.
