I have a really weird problem, I only noticed this when creating a new rule for a program, the attached screenshot (which paint doesn't like , and saves the entire canvas and not just the selected area), shows 'System' which turns out to be ntoskrnl.exe and shows from Microsoft, and an sfc /SCANNOW repaired some corrupt files, but 'system' still shows Chinese characters, but can only be seen when showing the list of app rules, and each time I open those rules the Chinese characters are random.
I've done a virus scan using Avast, I've done a malware scan using Malwarebytes, I've done a scan using Spybot Search & Destroy, and I've even done an safe mode scan and the PC is 100% clean.
As I said, excuse the screenshot, as mspaint doesn't know how to save a screenshot, but saves the entire canvas, regardless of selection.
