BSOD when I install full version of avast 5 internet security

Avast Free Antivirus / Premium Security
1

Hi guys,

I am desperate for a bit of help here and hope that someone can give me some advice. Here is the situation…

I downloaded the free version of avast! anti virus and decided to upgrade to the full version of Internet security 5.0
When I try to restart my computer to complete the install I get the BSOD and the following codes;

[b]DRIVER_IRQL_NOT_LESS_OR_EQUAL

Technical information:

STOP: 0X000000D1 (0X0000000000000010, 0X0000000000000002, 0X0000000000000000, 0XFFFFF8800164E5D6)

ndis.sys - Address FFFFF8800164E5D6 base at FFFFF88001620000, DateStamp 4a5bc184[/b]

I am using a Sony Vaio & Windows 7.

If I start the computer in safe mode, the full version of avast is still usable. I am unable to start the computer in safe mode with networking so I revert back to safe mode and then carry out a system restore to the point just before installing avast.

The computer will then start normally but I only have the free version of avast on the computer.

Thanks in advance,

Dan

Welcome to the forum, try a repair first and see if that helps:
Go to control panel choose Program and Features - select avast! then scroll down and select repair.
Reboot and see if that helps.

DRIVER_IRQL_NOT_LESS_OR_EQUAL is a sign of down level drivers.

Do you have all Sony Vaio driver updates ???
Plus is Windows 7 up to date ???

4

You should have the corresponding minidump file in C:\Windows\Minidump (and if you have bigger dump creation enabled, also C:\Windows\Memory.dmp file) - could you please upload it/them to ftp://ftp.avast.com/incoming ?

Vaio and Windows is all up to date.

@Bob - Should I try the repair in safe mode or Windows normal mode. (Safe mode will allow me to use full version & Normal mode will only allow use of free version)

Igor,

files uploaded…I think. Let me know if they are or not.

Thanks,
Dan

I have tried the repair option on both Avast free version and the full version.

I even tried turning off scan before windows start up to see what happened but I am still getting BSOD.

When in safe mode with full version I was having a play around to see if anything looked irregular (not that I am any kind of expert at all) but I did notice that Compatibility was set to Windows XP pack 3. I then tried to change it and Windows was recommended Windows XP pack2 which I agreed to. I then tried to open the program to see if it worked correctly and windows was saying that the program was incompatible?

London_Lad, thanks for your dump. Your last crash was caused by athrx.sys driver (Atheos network driver). I’d suggest you to update this driver, your current version is compiled on Jul 09 02:49:13 2009. Or uninstall avast firewall, it might help.

been following with interest as I have exact same problem with BSOD “IRQL NOT LESS OR EQUAL” when trying a full suite install. Dropping the Avast firewall seems to be admitting defeat. Does Avast intend a fix or does each user have to figure it out all over again?

10

acpressly, your BSOD may not be related to avast or avast firewall, we need to look at minidump to see where exactly your OS crashed. Please send me a couple of the latest minidumps (\Windows\Minidump folder) to kurtin@avast.com. Thanks.

pk you lovely man! You have fixed it 8)

Strange that my Vaio updates did not update that driver for some reason.

Thanks for everyone’s help on this

12

acpressly, your crash was also caused by athrx.sys driver (Atheos network driver), compiled on Jul 17 04:33:40 2009 (the identical crash as London_Lad). Please update this driver.

13

Thanks PK, will do updt ASAIKH (as soon as i know how) then retry my install. If this doesn’t work should I contact Support Directly?.

14

no, reply here

London_Lad said (see posts above) that so called “Vaio updates” worked well for him

15

Install successful! updt driver was easy to updt in control panel devices. I noticed my Windows Essentials is still running. Should I deinstall Essentials? Thanks again PK. This is my last post unless maybe I go to Praha in spring.

Yes. It can have conflicts with avast.

I have the same problem. I have been a longtime Avast user. Two PC’s in my home using Avast 4.8 until today. The Vista machine updated to 5.0 Internet Security without a problem. The Windows 7 machine will not do so. I uninstalled 4.8, and installed 5.0, got BSOD, computer wouldn’t start in any way except safe mode. I uninstalled 5.0 in Safe Mode, and the computer went back to functioning normally, and tried to install again. No luck. In Safe Mode, I tried to repair Avast, BSOD again. I uninstalled it again, downloaded the ASWCLEAR5 utility, uninstalled both 4 version and 5 version, and computer went back to normal. Installed one last time, and again BSOD, failure. So, I uninstalled one last time, and now my computer is again back to normal, but no Avast, which I love, and want to work. Can you give instructions for a minidump FTP? Thank you.

Once you’ve run the removal tool in safe mode after a normal uninstall through add remove program’s try the new pre release build 5.1.884 http://forum.avast.com/index.php?topic=69152.0

samwoodgoddess - Sounds exactly the same as my problem. Try updating your drivers (the offender for me was Atheros wireless network driver)

I thought that my Vaio updates were updating correctly but after pk saved the day, I realised that they had not been working properly and I had to wait for 45 minutes for the computer to update everything. After updating, I re installed avast and it worked fine.

If you want to upload your dump files it is pretty simple.
-Locate the files on your computer - C:\Windows\Minidump (and if you have bigger dump creation enabled, also C:\Windows\Memory.dmp file)
-Drag them onto your desktop
-Upload to ftp://ftp.avast.com/incoming (I use an ftp program called Filezilla which is free and pretty simple to use)

If you need any more help just ask

Success…the recommended build installed cleanly, no problem. Should I set Avast to receive Program Updates automatically, based on the prior errors? I couldn’t boot except into Safe Mode with the build I first installed…? Don’t want to update into another situation…?
