Norton Alert: Not a Valid Digital Signature

I've been using Calibre for years and I always update Calibre to keep it current. This morning I added some new books and when updating metadata, I got this message from Norton indicating Calibre doesn't have a valid digital signature. Why am I getting this message and is it okay to click OK?

Thanks.
