Windows 10 Pro 64-bit Version 1703 OS build 15063.483
No other security related software installed other than what comes with Windows 10 Pro from Microsoft. However, I believe i have all Microsoft stuff disabled except for bitlocker which is enabled
On this machine only ever used avast, prior to having problems, and have never had problems with it on this machine until recently (refer to “So I was having problems with Avast since a recent update” in Original Post)
