Hello,
I've just installed Windows 10 on my 2012 Macbook Pro retina with Bootcamp.
As usual, I installed Norton and turned sonar, boot protection and heuristics to aggressive.
After restarting the computer, while it's been booted for a while, I get a warning that Bloodhound.neuralMBR has been detected.
When I choose re-scan, the problem cannot be found and gets labelled "fully resolved".
I guess this is caused by Bootcamp's hybrid MBR/GPT boot manager.
I'll just reduce protection to normal/automatic until this gets resolved.
Just wanted to drop this here.
Best regards.
