I've installed windows defender, but the service won't start up. I get
get the error message :-

"The Windows Defender service terminated with the following error:
The signature of the certificate can not be verified."

I noticed that when I ran the msi file it complained about the
certificate saying that the manufacturer was unknown?, but I got it from
the Microsoft website. Anyone know how to fix it?
