I upgraded to Windows 10 this weekend. Avast first indicated that the firewall would not start and that there was an upgrade. Ran the upgrade for the program and the databases. I tried turning the Windows Firewall off and then start Avast Firewall but it still will not start. Any suggestions??

Also, the browser in SafeZone continually crashes every time I try to use it. It started when I upgraded Firefox. I have uninstalled the Firefox and cleaned everything out but the browser still crashes. Windows 10 did not resolve that issue, it is still ongoing.
