BSOD, BSOD, BSOD.
OK, I have just restored my last drive image taken before updating to this beta (now back with 17.5.2296), whilst I didn't find any issues (didn't really have time to do any testing). I felt like a crash test dummy and needed a seatbelt on my computer chair.
I had a BSOD during the restart after the update, after the reboot avast again asked for a reboot. Did that no BSOD, but whilst working I got another BSOD. The final straw was this evening when in the avastUI one of the screens was blank (white) and the UI locked up, couldn't close it.
I used tray icon to open about avast, and got to troubleshooting to disable the avast self defence module. I killed the avastUI.exe but it still didn't like that I had no UI but a ghost space on the screen and the avastUI still on the Taskbar.
I then got my third BSOD and with the time wasted already (hours) I wasn't going to keep on with this, I restored my last drive image which took between 15-20 minutes all in.
So far all appears stable on 17.5.2296 and have switched to Manual Program Update. I have collected 3 minidumps and two memory.dmp files if anyone is interested, no support package run.
