NEW Version: 19.2.2364 BSOD

Avast Free Antivirus / Premium Security

Hi Avast

not sure what info you need so could someone please advise.

back story.
gaming Clevo laptop which is roughly 7 years old. win 7 pro SP1 64bit
avast premier with just over 1 year licence before renewal.

my laptop has never had any issues since the day i bought it almost 7 years ago.
today has been the first ever BSOD and only since the latest 19.2.2364 build 19.2.4186.404 update.

opened avast to run a regular full scan. showed there was an update to load so i let it update. restart popup as always and after a restart bang, bsod and only way to carry on was a hard turn off.

downloaded who crashed and these were the dump reports:

On Wed 06-Feb-19 9:52:51 PM your computer crashed or a problem was reported crash dump file: C:\Windows\MEMORY.DMP This was probably caused by the following module: aswnetsec.sys (aswNetSec+0x3F9F9) Bugcheck code: 0x7F (0x8, 0x80050033, 0x506F8, 0xFFFFF800033061D1) Error: UNEXPECTED_KERNEL_MODE_TRAP file path: C:\Windows\system32\drivers\aswnetsec.sys product: Avast Antivirus company: AVAST Software description: Avast Firewall Driver Bug check description: This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap.Double Fault, indicates that an exception occurs during a call to the handler for a prior exception. Most often this is caused by a software problem (kernel stack overflow) but this can also 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: aswnetsec.sys (Avast Firewall Driver, AVAST Software).
On Wed 06-Feb-19 9:52:51 PM your computer crashed or a problem was reported crash dump file: C:\Windows\Minidump\020619-4742-01.dmp This was probably caused by the following module: ntoskrnl.exe (nt+0x93BA0) Bugcheck code: 0x7F (0x8, 0x80050033, 0x506F8, 0xFFFFF800033061D1) Error: UNEXPECTED_KERNEL_MODE_TRAP file path: C:\Windows\system32\ntoskrnl.exe product: Microsoft® Windows® Operating System company: Microsoft Corporation description: NT Kernel & System Bug check description: This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap.Double Fault, indicates that an exception occurs during a call to the handler for a prior exception. Most often this is caused by a software problem (kernel stack overflow) but this can also be caused by a hardware problem. The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

this happened 3 times so i rolled back 2 days with a system restore.
avast is still showing the latest version though.

since the first crash a few hours ago i can now no longer open (dont shout at me) nord vpn. up until this latest avast update it has opened and picked a server on startup without issues. now every time it opens it black screens and i have to hard turn off again. the latest dump reports above are after the latest black screen.

any advice would be greatly appreciated.

I’m using Vypr VPN, and the BSOD happens also for me (stop error 0x7F), exactly when Vypr VPN begins to connect to its VPN server. I initiated the Avast update myself, updating to program version 19.2.2364 (build 19.2.4186.404), and the VPN connecting immediately crashed my Windows (64-bit Win7 Pro). My VPN installation was broken by the crash, so I cleanly reinstalled it; and again got the same BSOD at the moment VPN nearly successfully connected.

Would be nice to rollback the Avast version to continue using my VPN, but I guess I have to wait and hope this gets fixed. Sadly, I recently terminated my Malwarebytes Premium subscription of several years due to a similar ruination of Windows (hard-freezing rather than crash… similar to a recent conflict with Avast’s RealSite component), and their support never fixed it nor acknowledged it - Hard to find a safe harbor with security software.

Hi. Same problem after update to 19.2.2364. I’m using ExpressVPN and BSOD happens when VPN begin to connect to VPN server.
Windows (32bit, Win7 Ultimate) Avast Premier 19.2.2364 BSOD stop error: 0x0000007F (0x00000008, 0x801DE000, 0x00000000, 0x00000000).
Where can i found avast 19.1.2360 offline installer ?

ahh so not just nord then.
id be interested in how to roll back to the previous version.

download Who Crashed mate and keep a screenshot of all the dump reports.

run this tool https://support.avast.com/en-us/article/33/ and then post up the file ID but then weve got to wait for someone to forward it to support.
i tried to go on live chat earlier and after typing it all out it just kept trying to send but went nowhere. i emailed them in the end.
not been able to use vpn since last night.

offline 2360 here https://forum.avast.com/index.php?topic=224223.0

question is will it overwrite with an older version.

let me know if it works as id best not try as have a support ticket flying around somewhere.

my crash report said it was a firewall driver issue but i turned firewall off and it still bsod.

10

offline 2360 here https://forum.avast.com/index.php?topic=224223.0 - it’s url 19.2.2364 now

I’m found 18.8 only https://forum.avast.com/index.php?topic=220640.msg1490449#msg1490449
https://install.avcdn.net/iavs9x-xp/avast_premier_antivirus_setup_offline.exe

Url for xp offline, but working at 7 too. I’m stop upgrade program to new version. Now i have Avast 18.8 and normal working VPN service. And i’m waiting when avast developers do something with 19.2.2364 VPN BSOD problem.

11

I uninstalled just the firewall component of Avast, and that stopped the Windows crashes. Permanently “turning off” the firewall wasn’t enough - it still crashed even then. But uninstalling the firewall component (and ensuring the generic Windows Firewall is instead turned on) puts me in a good state to await a later fix / update. The “WhoCrashed” report had already suggested that a driver for the Avast firewall caused the crash (for my environment, probably various VPN services being handled by Avast firewall … even when you’ve told Avast firewall not to be “on”, i.e. observe or handle internet traffic). So that guided me to try this.

12

You’re welcome. Also forwarded.

Hi All, we identified wrong interaction with OpenVPN driver which causes BSOD UNEXPECTED_KERNEL_MODE_TRAP. So, please could you tell me if do you have OpenVPN instaled?

14

hi and thanks for the update.
i do not have open vpn here, actually never heard of it before.
i use nord vpn

is it worth me deleting avast premier using uninstaller and loading 19.1.2360 using offline version.
i need vpn to be loaded by 8pm tonight for hospital work from home.

15

Nord, as well as many other VPNs use OpenVPN as the base of their product sort to speak.

I have the same issue as described with my VPN that used OpenVPN as the base.

16

ahh got ya, thanks. i had to google it as i thought it was a stand alone vpn.

17

ok
so that didnt work.

removed in safe mode using avast tool. 19.2.2364 build 19.1.4142.454

as previously said, without the antivirus loaded my vpn loads and connects.

installed premier using ofline link on here rollback 19.1.2360

opened and checked version and it is still 19.2.2364 but the build has changed to 19.2.4186.404

but once again as soon as i open nord it blue screens.

i am now going to have to stand down from my hospital oncall work as i need a vpn.

NOT IMPRESSED AVAST

Where did you get the offline installer from for v19.1?

When you installed Avast via the offline installer, was your internet connection disabled? Avast automatically downloads the latest version if you are connected to the Internet.

You need to use the offline installer with your internet disabled and then immediately set the program update option to manual via Settings. Then you can re-enable the Internet.

On a side note, I’m using NordVPN with Avast Internet Security v19.2.2364 on Win 10 Home and haven’t had any BSODs while connecting/using the VPN.

19

I have this BSOD issue, and I use Vypr VPN. I use their “Chameleon” mode protocol, but it itself is using OpenVPN 256-bit:
https://www.vyprvpn.com/features/chameleon

So yes, your explanation seems to fit with my crash scenario.

20

DOH! sorry im so stressed out with this and explaining to work why i cant work from home checking brain scans.
your right, i was still connected oopps.
i will try again.
this was the page i got the installer https://forum.avast.com/index.php?topic=224223.0

i did have it unplugged from net but plugged it back in to check the vpn which then loads and connects as it always has done.
does anyone from avast think this issue could be rectified so as me and the others using various vpn’s will be able to use them again while avast is running.
the issue was caused by an update so can it be rectified by a later update.
sorry for all the questions but i have a year subscription left here and over 2 years vpn subscription.
and the most important thing is i will not be able to do any more oncall for hospital until this is rectified.

EDIT:

so once again a big fat fail.

used clean tool in safe mode > deleted > unplugged from internet > used offline 19.1.2360 and loaded > went to set to ask first before updating and 19.2.2364. still loaded but with a different build of 19.2.4186.0

can anyone post to another page with 19.1.2360 please as im now pulling my hair out. thanks.
