Title: BSOD after Avast Update
Post by: REDACTED on January 29, 2015, 11:29:04 PM
Hello,

I have a problem with my laptop since I tried to update Avast Internet Security. I have Windows 7 and Avast 2014.9.0.2021 installed.
I got a Blue Screen and I tried to restore Windows. This did work after some tries, but when I restarted my laptop after that again, I got again a blue screen.
This went on and on and I read that more people were having trouble with this. So I tried their solutions, I uninstalled Avast, also with the clear tool, but that didn't work, I still got blue screens.
I really don't know what to do.

I used a program for windows to read the dump file, but I don't understand it.
It says:

Can anybody help me?

Thanks in advance,

Check for newer drivers for your wifi and install them.
If there are no newer drivers, reinstall the current ones.
It may help.

Doesn't look like Avast's fault.  As Eddy suggests, try to get newer (or even older) drivers for your Atheros card.

Thanks for the advice.
I thought it was due to Avast, since it happened twice after installing the update..
But I found the driver, however, I couldn't fix it.
After my laptop finally did a recovery and started again, it couldn't find an upgrade that was certified for that driver. So I wanted to just reinstall it, and I searched for the right software on the Microsoft and HP websites and also on the cd's I got with my laptop, but I couldn't find anything. I actually found something on another site (Driversmax), with the same code and date as my software, but that software said it wasn't suitable for my laptop.

So now I just disabled the device and my laptop is working fine again, I guess. Because I don't know what this driver does or what I am missing right now. But this doesn't seem like a permanent solution.

Could you may be help again? Cause I don't want to uninstall the driver and not be able to install it again..

You can find the latest drivers here:
https://www.atheros.cz/atheros-wireless-drivers.html
Get the latest ones and install them.
If Widows/Microsoft say they are not certified, just ignore it.
It only means that Microsoft hasn't tested them (yet).
The manufacturer (Qualcomm) certainly has done so.

Thank you, I will try that.
I only don't understand all the Atheros numbers. Do I need all the drivers on that page?
(at least, those for Win 7 32 bit?)

No, just the one for your device.

Right click "my computer" > properties > hardware tab > device manager > network adapters
The device should be listed there (or at least somewhere in device manager)
