Title pretty much says it.
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.
