Unfortunately, my computer skills are completely average.
Since everything important in my life is at least partly Web-dependent, I tend to panic when hardware or software is not behaving as expected.
The other thing you can do is nothing... And just see where this all ends up. Microsoft is basically going to be making software security companies relevant again.
My guess is that computer security software businesses are completely up to the task and will be offering all sorts of products to protect your Windows 10 system. I am sure that there will be lots of threads here and other places that will recommend products designed to keep your current system safe and secure.
