I often see this situation. First of all, make sure that the network connection is normal, which means that all web pages can be accessed. Then there is no virus, no malicious plug-ins, that is, to do a total antivirus. But my computer is not poisonous, all the time. Or you can delete 360 to see. Now Tencent and 360 have opinions. This always happens when you don't play games for a long time. You opened a QQ game room and then went to do something else. So don't give a speech in your room right away, or watch others play games to see if you can solve your problem.
