I’ve done multiple Full Scans and Malware Byte Scans following this and they’re not coming up clear, but I didn’t even do anything.

I’ve also not updated recently (10+Days ago) and also rebooted and done multiple scans again.

What can I do next?

Ah Thanks for the quick reply, I just went and checked now and the entire contents even with hidden file of WinSXS in windows.old is gone, I can’t even see it in there anymore, should I just delete window.old anyway?
