Its been four days since I posted the question.As you said its weekend.But What about the next days.And again this weekend is coming.So when there are going to answer the question.The problem is faced by many people around the world.I checked recently and found out many people posted this problem in Nvidia Forum.But after talking to them and Microsoft,Lenovo there were helpless for this problem.Then I posted this in AVG Forum.

I disabled from taskbar and the Firewall was running.Except that evrything is disabled in AVG for few minutes
