Hi there, hope you're all well.
Having a little problem where my windows security doesn't appear to be present. I type windows security in the search bar, and a settings screen comes up but it's completely blank. It wont let me scan for threats, it just stays at 0%. Any sort of solution ideas would be greatly appreciated. Mentioning in case it helps, a while ago I got what I believed to be a trojan, where a window playing advertisements was always open in the background until I finally shelled out the dosh for a premium antivirus which fixed the problem. I deleted the antivirus a while ago and it's no longer on my system so I doubt it could be that controlling it.

Many thanks
