Avast install nightmare

So i downloaded and installed the newest version of Avast onto a windows xp and a windows 7 PC and it has been a nightmare from the start.

The whole setup process was painfully slow, hogged my memory like crazy and it kept freezing. When i finally got it installed i tried to register it and the only thing that happened was that my screen froze when trying to do so. I am glad i didn’t start the update to my third PC and i still have version 7 and that it is working great.

So is this a bug in the software or what is going on? Before you ask, i can’t have any corrupt files as i did a whole reformat just before installing (or trying to install) Avast newest version.

Does anyone know what is going on? Anyone have any tips on how to fix this?

Do you have any other antivirus programmes on the computer ?

No other antivirus on the computers and no corrupt files either. They are both freshly formatted computers. I ran DBan to delete everything, than i re-installed the OS and the drivers. After doing that installed Avast which was a painfully slow process, and after downloading it and installing it that is where my worst trouble began. It is hogging my CPU memory big time and it has slowed down both computers bad. And if i try to register it, it freezes my computers.

Like i said, i had never had any trouble with Avast until this new version 8. I have a third PC that i still have version 7 and it is working great.

Where did you get the download from ? As I have Avast 8 on both win 7 and win 8 64 bit with no problems at all

Direct download links
http://files.avast.com/iavs5x/avast_free_antivirus_setup.exe
http://files.avast.com/iavs5x/avast_pro_antivirus_setup.exe
http://files.avast.com/iavs5x/avast_internet_security_setup.exe

I went to Avast.com and hit download which opened a box and once i clicked on i want free protection, it took my to CNET to download the software.

Hmm I never trust a cnet download… I always get it direct if possible.

Could you fully uninstall Avast from one system and use the removal tool that Rejzor has made … Available here https://skydrive.live.com/?cid=94a12102e5094675&id=94A12102E5094675!952 (AvastCleanupTool)

Then do a custom install of Avast 8 from the direct link

After some problems at Windows booting I’ve deleted AVAST and did run Rejzors removal tool. At least I think it did as there is only a quick flash of a message immediately on starting to run the tool and then nothing afterwards. Is it running in the background silently or do I have to do this in save mode?

I will re-install AVAST 8 afterwards.

PS. Just tried to run in Safe mode and the uninstaller process seems to go further until a message comes up that it cant access remote … something ???

Why does this uninstaller need to access anything ‘remote’? I have remote registry access disabled in services, is this the problem?

Mmmmh, well, this time I used the AVAST uninstaller as linked by DavidR from save mode. Then installed again clean.

Straight away, same problem when booting from cold, gets to just after the Windows screen and then shuts itself down again to re-boot.

No problems when AVAST is not installed.

I tried to send a minidump file but windows won’t let me …

These probs have only been since the latest update (not the first V8 release which was fine).

Do you have any minidumps ? If so could you upload them to a file sharing site where I can collect them and then analyse them

This will read stupid but how?

I tried to submit a minidump file by email but windows just says it cannot open it/I have no access …

What file sharing site do you mean?

Thanks and regards

You can create a free account here, then upload the file and post the sharing link here
http://www.mediafire.com/
But first go to c:\windows\minidump right click the latest one and select copy to desktop then upload from there

Opened the account and transferred the minidump file to desktop.

Can’t upload as administrator permission needed??

I am administrator ???

regards

OK next trick will be to zip the file and then try to upload… If that fails we can take ownership of it

No read permission … wont even let me zip it.

regards

OK download this zip file to your desktop
https://dl.dropbox.com/u/73555776/TakeOwnership.zip
Unzip and extract InstallTakeOwnership.reg to your desktop
Double click and allow to merge with the registry
Now right click the minidump and select take ownership
A black box will open and do its thing
You now own this file and should be able to upload it

Did what you said, clicked ‘take ownership’ …

when trying to upload still the same message; You don’t have permission …

This is fun :frowning:

regards

OK I will let you do the analysis

Please download and install whocrashed from here http://www.resplendence.com/downloads
Run Whocrashed and press the analyse button

https://dl.dropbox.com/u/73555776/who%20crashed.JPG

When it has completed scroll down where it states crash dump analysis and either screenshot or let me know what driver is responsible

Ok, that worked.

Thanks for your help

regards

Crash Dump Analysis

Crash dump directory: C:\Windows\Minidump

Crash dumps are enabled on your computer.

On Fri 15/03/2013 17:43:23 GMT your computer crashed
crash dump file: C:\Windows\memory.dmp
This was probably caused by the following module: aswsnx.sys (aswSnx+0x27803)
Bugcheck code: 0xA (0x10, 0x2, 0x0, 0xFFFFF80003CB7EE9)
Error: IRQL_NOT_LESS_OR_EQUAL
file path: C:\Windows\system32\drivers\aswsnx.sys
product: avast! Antivirus
company: AVAST Software
description: avast! Virtualization Driver
Bug check description: This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.
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).
Google query: AVAST Software IRQL_NOT_LESS_OR_EQUAL


Conclusion

One crash dump has been found and analyzed. A third party driver has been identified to be causing system crashes on your computer. It is strongly suggested that you check for updates for these drivers on their company websites. Click on the links below to search with Google for updates for these drivers:

aswsnx.sys (avast! Virtualization Driver, AVAST Software)

If no updates for these drivers are available, try searching with Google on the names of these drivers in combination the errors that have been reported for these drivers and include the brand and model name of your computer as well in the query. This often yields interesting results from discussions from users who have been experiencing similar problems.

Read the topic general suggestions for troubleshooting system crashes for more information.

Note that it’s not always possible to state with certainty whether a reported driver is actually responsible for crashing your system or that the root cause is in another module. Nonetheless it’s suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further. [/b]

aswsnx.sys is the culprit … Part of the sandbox I believe

Could you do a custom install on Avast and untick behaviour shield and sandbox
If that then appears to fix the problem then go to control panel > programs and features
Select Avast > change and then tick behaviour shield (a reboot may be required)
Does the problem return ?

Will do.

Thanks for the fantastic guidance and I’ll report back tomorrow
