Win7 BSOD after EVERY avast scan shutdown

Avast Free Antivirus / Premium Security
1

For the last couple of weeks when I start up my laptop after an avast scan shutdown my laptop comes up and I get the BSOD and it reboots and comes up fine.

This only happens after a scan shutdown and not when I shutdown normally. It also happens every time.

It’s not a big deal to me, and it doesn’t happen during the scan, so I run scans a couple of times a week and I’ve turned off the shutdown option. I turned it back on to get some minidumps to see if I can see a trend, but I haven’t.

Has anyone seen or hear of this before?

Win7 Home Primum up to date and advast 7.0.1426

Please, go to folder \windows\minidump and send the newest (recent) .mdmp files for analysis.
There is also C:\Windows\Memory.dmp file.
Better if you can add some information about the BSOD and the link for this topic in a readme.txt file, compress (zip) together the readme.txt and the Memory.dmp, rename it with a unique name.
Upload it to this anonymous write-only ftp server location: ftp://ftp.avast.com/incoming/

Post back here when you’ve done it.

Okay, uploaded ShutdwnBSOD.7z to /incoming/ It includes the MEMORY.DMP, a text file ShutdwnBSOD.txt and the minidump from the same crash as the MEMORY.DMP.

Good luck with it.

Let me know if there is anything else I can do…

I went back and looked at all Critical alarms in the Event Viewer. In total I had 13 Critical alarms (BSOD) and they were all the same alarm.

“The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.”

Log Name: System
Source: Microsoft-Windows-Kernel-Power
Event ID: 41
Task Category: (63)
Level: Critical
Keywords: (2)
User: SYSTEM

Hope this helps…

BTW, the BSOD DOES NOT happen every time!

Last night I changed the laptops power settings. I changed “While plugged in” from “Sleep in 45 minutes” to “Sleep = Never”. I scheduled a quick scan with shutdown and it successfully ran and shutdown the computer. When I restarted this morning, no BSOD. Sleep may be the key issue.
