I have just managed to get my grand daughter's laptop going again after a vius, and scans say all is well, including, at last windows security centre and the MSE is running. However I cannot get the windows (7) firewall to turn on - a red bar is showing and a splash screen says Action Centre cannot turn on Windows Firewall When I try to turn it on manually then "Use recommended settings" a circle rotates but nothing happens. Tried a MS Autofix from MS support - still no joy. I hope it can be fixed, if not is there another free firewall? There does not seem to be one in the programme files.
