I've just bought a new Acer Spin 5 and I am a little worried the antivirus hasn't been installed correctly. I was under the impression all windows pcs come with Windows defender antivirus. I have windows security which I understand is not antivirus but merely the app to view any antivirus on the computer. It seems to have a 1 month trial of Norton on it, but Windows defender antivirus and windows firewall appear to be off with no option to turn on. And when I search for the Windows defender it doesn't even seem to be on my computer at all. And norton seems to only be half protecting me, (no internet security just device) and in the online account it says even device isn't protected. Plus if its only a 1 month trial id rather stick with the standard windows approved antivirus to avoid any complications and also to avoid additional costs. Anyone else with the same computer have this problem? and able to shed light on exactly what is happening? is this right? and what antivirus you use?
