I’m working on an Acer Laptop running the latest Windows 10 preview.
If deep scan is enabled, PowerShell pops up along with an Avast Deep Scan window, then a window pops up that says PowerShell has stopped working, and a couple seconds later the computer hits a BSOD saying Page Fault in Non Paged Area.
If I disable deep scan, PowerShell Launches normally.
I have seen other posts about issues with windows 10. please be aware that windows 10 is not officially supported at this time, seeing as how its not even beta yet. that being said, I think its a combination of things. I have not had any of the issues that others have reported with avast cloud and windows 10, including this one. i can launch powershell with deepscreen enabled and i have no problem at all. possibly the combination of avast and some other apps you have installed?
