today i updated avast from 5.0.677 to 5.1.677..at least thats what the "update" section says..furthermore there is a message saying that there is a new version available(5.1.864)..so i click update and then it says that its already up to date besides the fact that its not the 5.1.864..below are 2 photos explaining the problem.
thanks in advance,
george
