I don't think so - There was some McAfee stuff, but I have uninstalled that (I think that was after installing Avast).
On start site of the Avast interface it says everything is on, but still under 'Firewall' under 'Tools' it says something like this: "We recommend you reboot your system. Some Firewall features will only work after a reboot." - I've rebooted several times, but the message doesn't change.
Do I have to turn off the Windows Firewall in Windows Defender? Will this help?
