A while ago I got a persistent Blue Screen of Death (BSOD) on a Windows 8 machine telling me DRIVER_IRQL_NOT_LESS_OR_EQUAL. This error usually means there is a bad driver on the system. Using WhoCrashed, a useful program to determine what has crashed the system, I found it to be aswnet.sys, which is a software driver installed by Avast.

A quick Google search brought my to a forum topic on the Avast forum. If you are interested in a long read, find it here. But if you are like me (hyper impatient), you want a solution straightaway.

Right 😉 Go here , download the patch , and extract the two files that are in the zip into c:\windows\system32\drivers ( overwrite the old ones ) and reboot.

This should fix it for now, until the next update.

note: Applicable for version build 7.0.1474 only!

You find your version number when opening the Avast console (right click the avast icon in the taskbar and Open Avast user interface),

it’s right there.
