Not protected message
I'm getting messages from Windows saying I've no anti-virus software running and from Acronis saying 'Not protected from malware'. Hitting the 'Turn on protection' button has no effect on this, nor is their any more information as to why this is the case. See linked images. Going into Settings / Reset to defaults doesn't help this. Saving a probable trojan from a scam email confirms protection isn't in place and my system is exposed. Suggestions?
