Title: BSOD - "DRIVER_IRQL_NOT_LESS_OR_EQUAL (aswNetSec.sys)"
Post by: REDACTED on September 06, 2016, 12:07:43 PM
Hello,

Ever since updating my Avast IS a few days ago (03/09/16) I'm getting BSOD when I start my computer, with the message "DRIVER_IRQL_NOT_LESS_OR_EQUAL (aswNetSec.sys)".

System:
-Intel Core i5-4670 CPU @ 3.40Ghz
-Ram 16.0GB
-Type 64-bit operating system, x64-based processor
Windows 10 Pro

I've been browsing the forums for a bit, but haven't found a solution yet. Please help!

I've tried repairing Avast with the repair tool, as well as doing a clean install. I've updated all drivers using Device Manager (even the hidden ones), but the problem still persists. Only thing that seems to get rid of the BSOD so far is uninstalling Avast IS.

Did you use aswclear when performing the clean installation ?
What exact version of avast ?

Hi Eddy, thank you for your response.

No, I did not use aswclear. Would this make much of a difference from deinstallation (control panel > uninstall a program)? This 'regular way' of deinstallation removed the BSOD while Avast wasn't installed.

Avast Internet Security
Program version: 12.3.2280 (build 12.3.3154.2)

Yes it sure will make a diiference.
Uninstalling thorugh control panel leaves a lot behind.
aswclear removes some of those leftovers.

I followed the instructions above for a clean install, results:

1st time I tried to install Avast IS again, I got the same aswNetsec.sys error on the reboot. The automatic reboot that followed this BSOD led to a driver_page_fault_in_freed_special_pool rzudd.sys BSOD.

I tried a clean install again, using the tool, and this time I got the aswNetsec.sys BSOD *during* the installation of Avast.

Which version of Avast ??? What other security related programs are you running ???
Get the latest version from here: https://forum.avast.com/index.php?topic=189836.0
I suggest using the off-line installer.

rzudd.sys is a driver for Razor keyboards.

Do you have the Anniversary update for Windows installed ?
Do you have any other security (related) software installed ? (or was there)
Seen any other problems with the system lately ?

As far as I know I was running the latest version of Avast Internet Security, which I downloaded on the 3th of september. I'll try a clean install with the offline installer version provided from your link this time.

I didn't have the windows anniversary update installed, working on it now. I thought this update would've been automatically installed on my pc when it was ready, but apparently not.

I don't have any other security related software installed. This pc has only known Avast and the standard windows security.

No other problems with the system before the BSOD's started happening. Before I got my first  aswNetSec.sys blue screen, I noticed my cpu being heavily taxed (up to and above 90% usage) after the first time I tried installing the Avast IS update (Program version: 12.3.2280 (build 12.3.3154.2)). PC became very slow to respond. This hasn't occured since I tried the reinstalling/repairing by myself before I decided to post here.

I've seen the rzudd.sys error once before this weekend, after deinstalling avast. Found out it was a razor driver and updated Razer Synapse, surprised to see it come back again though. Again, I manually tried updating all my drivers through Device Manager as well.

I'll come back with the results after finishing the anniversary update and the offline Avast install.

Arjen:  I had a similar problem as you seem to be having; Windows 10-64 AU; once the latest (at the time) avast update was installed; I had BSODs for two consecutive days; different issues for each BSOD.  Uninstalling avast cured the BSODs.   Unfortunately I've already paid for the product and I may try installing it again if a new release comes out just to see if it's more stable.

I'm running Windows 10 Pro Insider Preview 14915 and the latest Free version of Avast. No problems, no BSOD etc.

Looks like a clean install (with avastclear and the offline installer) combined with the windows 10 anniversary update did the trick.

Thank you for your help!

Please, check folder \Windows\Minidump, if exists. Are there any dmp files?

Hi Three days ago, I started receiving this BSOD with the aswnetsec.sys identified as the culprit, it has crashed my computer at similar times, when I was switching windows. I have Windows 7 Ultimate version, and everything is up-to-date.
I have Avast Business Security Suite.
I usually have several programs open and I am afraid corruption will occur if this keeps happening, have done the Repair, clean install. What's Next?

I'm not sure if this belongs in a new thread or not, but I am having a very similar issue.

I am a user that likes to leave my PC on 24/7 so it can run automated tasks while I'm away, lately I've been returning to my PC to find it idling at the login screen. Checking windows event logs shows multiple crashes while I am asleep/at work, seems to average about 2 per day/night cycle.

While trouble shooting the issue, I learned about a tool from Microsoft for testing installed drivers called Driver Verifier (https://msdn.microsoft.com/en-us/library/windows/hardware/ff545448(v=vs.85).aspx), and set it to test every installed driver on my system. After restarting I got the same BSOD error message as the OP.

I ran a follow up test using driver verifier to test only the aswNetSec.sys driver in isolation, and got the same result. I did a clean install as instructed in this topic, and the issue persists.

I don't know whether or not it's related, but I also have a DPC latency issue, leaving my PC on for an extended period of time causes my DPC to slowly rise, to the point where I notice audio stuttering. Disabling my ethernet adapter significantly improves my DPC latency.

Please, check folder \Windows\Minidump, if exists. Are there any dmp files?

I have a bunch of dump files from my various crashes, I am a bit hesitant to share the contents of my computer's memory with the entire world, but if there's a special tracking system for customer issues, I wouldn't mind uploading them directly to Avast, as I'm sure they'll help with debugging.

I checked the latest one out myself, and the most interesting bit to me looks like this:

Quote
DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: fffff684c742cf5c, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation
Arg4: fffff80b72460b60, address which referenced memory

I think the gist of it is, the driver tried to access a bad memory address, which is likely a problem only the Avast dev team can fix  :P
