I had the same problem. After it updated i got an instant BSOD and thereafter i got one every time i boot into my desktop.
I had to boot into safe mode and manually uninstall Eset Smart Security with the .exe from the website. After that i can boot into windows again just fine and everything is good. I have been using this virus protection for years and have never had an issue like this before. I thought my computer was a goner.
I also have a gigabyte motherboard(z97-sli) and use the software it came with.
