Can you help me?My v. is 4.5.523 and virus database 0447-0.When i go to control panel add-remove avast change and check the network shield, i robooted the computer but network shield still isn’t in the installed providers(windows didn’t restart,there was a message that windowas is busy,and i clicked to end task-is this the reason?)And when i updated to this version and restarted the pc(the internet stopped for a while) in few minutes there was a warning message(error while trying to attempt update)The automatic updates are set to ask when update is available.When the internet camed i manually updated and everything was fine.So is now everything ok with my avast and what to do to make the network shield working?
