Computer flashes black then blue screen?

Hi,

Am running Avast Pro.

This Windows 7 suddenly crashed - black screen - recovery - then blue screen & shut down. This was accompanied by a ‘Raedon driver failure’ notice. Today I got a different error pop up reading ‘wermgr.exe error’ so I googled it and a page advised downloading a ‘Security Task Manager’ which I did. Then the computer went haywire and it would not activate the STM download. I then did a bootscan which didn’t flag anything up sinister but I did not know where to find the full Avast log file for the scan.

Oh, I found the short scan report - it says “no virus found”.

What on earth is going on then please? why the crashes & crazy behaviour? The tool bar at the bottom of the screen has also reverted to an early version of the Windows tool bar with a square ‘start’ button instead of the Windows 7 round one :-o

???

Thanks.

Check this C:\ProgramData\Avast Software\Avast\report\aswBoot.txt (Vista, Win7 or later OS location), I haven’t run a boot scan for some considerable time so I’m not 100% sure this is the same location and file name now.

If the bootscan didn’t reveal anything (it is interactive, in that if there is a detection, the user has to choose what to do), then I don’t believe there will be anything in the scan report.

Thanks, found something but I could not open it - ‘bootstat DAT file 18.01.2016’. Can’t attach it either, Avast Forum won’t accept it as an attachment.

Well that certainly isn’t the boot scan log/report as that has always been a .txt file.

Since you can only attach the following text files, .txt and .log that would be why you can’t attach it.

Where did you find this bootstat.dat file ?

I wonder what this post is doing in this forum.
There is no indication at all that avast has something to do with it.

Came up under Avast on the Windows search option. Where can I find the detailed logs for Avast scans please - I don’t see them?

Thanks.
