I’m running Avast 6.0.1203 and my laptop recovered from BSOD.
I ran Who Crashed software and got a conclusion that I wanted to copy in here but don’t know how to do that. I saved it with Fast Stone Capture but don’t know how to insert the text.
Analysis is Avast Virtualization Driver is at fault. aswsnx.sys (avast! Virtualization Driver, AVAST Software).
I’m over my head here but I did run a malware scan and machine is clean.
What do I need to do?

Upload any minidump or memory.dmp files, zipped to reduce size. Give the zip file you are uploading a unique name (e.g. forumusername-mem-dump.zip, etc), so they can identify it. It might not be a bad idea to create a text file (readme.txt) with any relevant information, avast topic URL, user name, etc. etc. in the zip file. Not to mention posting the name of the file you uploaded in the topic acts as another searchable reference.
Memory dump locations, Mini Dump files in, C:\Windows\Minidump\ - Full Kernel dump file, C:\windows\memory.dmp
Upload the zip file to the ftp server ftp://ftp.avast.com/incoming:

Excuse if I’m teaching your granny to suck eggs:
Now you make your first windows explorer connection to the ftp link [nobbc]explorer ftp://ftp.avast.com/incoming[/nobbc], now open another explorer window where you locate your unique zip file containing the dump and readme.txt files; drag and drop that file into the other explorer window (right hand side), no need to click enter or any other action.
got the mini dump file compressed. When I go to the ftp link I get only a heading screen with
Name Size and Last Modified. I don’t know how to get any farther or find the screen you show above to drag and drop the file. At first I dragged it to the right side of the heading screen
but now I know that wasn’t right. The compressed file is now located directly under the original
file and I renamed it as dford3772mini 081211-01 dmp.
Help me get it to the ftp page please; this is pretty complicated stuff you know. LOL

This info from Who Crashed:
On Fri 8/12/2011 5:00:59 PM GMT your computer crashed
crash dump file: C:\Windows\Minidump\Mini081211-01.dmp
This was probably caused by the following module: aswsnx.sys (aswSnx+0x13154)
Bugcheck code: 0x50 (0xFFFFFFFFD8A5B8DC, 0x0, 0xFFFFFFFF82C3AAB4, 0x2)
Error: PAGE_FAULT_IN_NONPAGED_AREA
file path: C:\Windows\system32\drivers\aswsnx.sys
product: avast! Antivirus System
company: AVAST Software
description: avast! Virtualization Driver
Bug check description: This indicates that invalid system memory has been referenced.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: aswsnx.sys (avast! Virtualization Driver, AVAST Software).

@dford3772,
Please read again the instructions DavidR posted. His post explains how to upload your zip file.
It is very similar to a simple “drag&drop” using Windows Explorer. The only difference is that you only have “write-only” access, so once you “drop” your file in the ftp site, you won’t see anything in there (you don’t have “read” permissions).
So, as said, please read carefully the instructions from DavidR. He also gave more than one alternative to get the upload done.
If you still have doubts, please don’t hesitate to ask again.
I have been reading about minidumps and the file I have is only 26KB. I found nothing about a
full kernel dump but I understand that a 32 bit machine cannot handle it.
David’s directions are clear but I simply don’t have the experience to fully interpret them.
The actual dump file is 136 KB and my compressed one is 21KB.
If this is a corrupt Avast driver why wouldn’t a simple clean up and uninstall/reinstall of
Avast work?
I’ve seen a fairly large number of users with this problem. I will say that over the years I have used Avast this is the first BSOD I’ve had; I want to get back to that clean state again.
Which part don’t you have the experience to implement ?
BSODs generally don’t occur because they are corrupt, but because they come into conflict with another driver. In fact if they were corrupt they wouldn’t run at all and you would no doubt get avast errors, plus it it weren’t running there is little chance of conflict with another driver.
Let’s try this:
1_ Right-click at ftp://ftp.avast.com/incoming and select to open the link on a separate new window.
2_ Using Windows Explorer, get to the folder where you have your zip you need/want to upload.
3_ Click (and maintained pressed) over you zip file.
4_ Drag your zip/mouse over the new window where you have open the ftp location.
5_ With the mouse over that FTP location, release the mouse (drop the file), just the same as if you were copying a file from one folder to another.
Now the file should be in the process of uploading. You won’t see any new file in the FTP location/folder, simply because you don’t have “read” permissions. You can only “write” (upload) a file to that FTP location.
Report if that seems to work or if you find any problems.
Hopefully, the zip file will be uploaded and someone from Avast Team will come here to this topic to report about it (and eventually give you more instructions).
I right clicked on the link and opened it in a new tab (I’m in FF). I get only the header page
of Name Size and Last Modified while title is Index of FTP. Nothing opens that even resembles
the sample page that David sent.
Open “Computer” or any other Windows Explorer folder. In the address bar, where it says “Computer”, type or copy the ftp address starting and including the “ftp://…” part. Press and it should give you something very similar to that screen DavidR presented.
In desperation I went to IE9 and the directions worked. I got the page and dropped the minidump file on it and it went through the motions.
The sample image page is windows explorer.
I never found this worked with firefox unless you use something like the FireFTP add-on in which case you need some experience of using an FTP program.
That is why we are trying to keep it simple by just using two separate windows explorer windows. The first one that you copy and paste the [nobbc]ftp://ftp.avast.com/incoming[/nobbc] URL into the address window.
In the second explorer window you navigate to the folder that your zip file is located, now drag the zip file from that explorer window and drop it into the first one.
Edit: I see now you have it done in IE9.
So far no response from Avast on the dump file that I uploaded. How long am I likely to wait?
Donna
No one her can answer that, remember that you uploaded during a weekend, so that may have an impact also.
Since part of the posts here are about how to upload, please repeat here the exact and complete name of the file you uploaded, so it would be easier for Avast Team to read here about it and give instructions.
Alternatively, upload a new zip including the memory dump AND with a text file with the link to this topic and any relevant information.
After uploading, please report here the unique name you used for the zip file.
I named the compressed file I created in Windows Explorer [dford3772 mini 081211-01 dmp]. I can reload it with a better name but I do not know how to do a read only text file of it. Once I
find out how, is that done from the original or the compressed file?
Sorry to be so much trouble but this is pretty complicated stuff for a mind as old as mine. LOL
Donna
Well, first, I think that the file name should be a simple thing. Generally speaking, any “unique” name should work, like “dford3772-2011AUG08DMP.ZIP”. Avoiding blank spaces in the name is a good idea (it makes it more clear when referring to it), but it should be fine either way.
What I didn’t see was the extension (or the type) of your file. Is it “.dmp” or have you zipped it (“.zip”)? It is possible that your Windows Explorer is not showing the “known” extensions (“.zip” in this case), so the “type” of file in Windows Explorer should indicate this info.
I’m sorry but I didn’t understand your question about “how to do a read only text file of it”.
If you meant that you want to add a text file with more info (like the link to this same topic http://forum.avast.com/index.php?topic=83061.0), then just open “Notepad”, write the info you want, save it, and make a zip archive containing both the text file and the memory dump file. Then upload it and report here the complete file name.
If you still have any questions, please don’t hesitate to ask.
Let’s hope someone from Avast Team can check your uploaded file and give instructions if necessary.
I just sent this [dford3772-2011AUG12dmp.zip}.If this doesn’t work let’s just give up on this
crash and wait for the next or maybe there won’t be one. I’ve fooled with this far longer than I wanted to and I know that is true for you too.
It is interesting to me to note that the day of this crash I had trouble with all 3 of my PCs
crashing AFTER or during a download of the recent sunami of Windows updates. Perhaps this one
was a glitch too because the others have Avast and they are running after recovery.
Thanks for trying,
Donna
After both Opera and Safari crashed on Win7 I’ve done lots of reading and it seems the latest
update of Adobe 10 flash player is creating havoc. From what I’ve read it can interact with
antivirus also but no one seems to really know what to do to fix the crashes.
I have that new update so that might be the root of some of the problems I’ve been having
with all my PCs.
Just Google the problem but even Firefox has shown problems as well. Just hope this info
can help others know what is wrong. To fix???
Donna
