I did a search and didn't find what I was looking for. I am periodically getting BSODs, and based on some other forums it could be antivirus issues. In Windows 7 and 8/8.1 I used a combination of Avast Free and Malwarebytes. I did a clean install of Windows 10 and am using the most current versions of both. There are rumors that Avast may be causing issues, including BSOD (I believe the reported cause was BAD_POOL_HEADER). What alternative or combo have other people found that have been stable and provide reliable protection. Is Windows Defender by itself or with Malwarebytes (I haven't heard complaints with it messing up Windows 10) a safe option?
