Avast conflict with Netio Driver ?
« on: May 10, 2020, 01:14:28 PM »
I have used Avast free AV for many years on my Windows XP and now my Windows 10 - 64 bit computers.
In recent months I have been getting random NETIO.SYS DRIVER_IRQL_NOT_LESS_OR_EQUAL errors.

Whilst being incredibly annoying, Windows automatically fixes the matter, restarts my PC and all is fine again until the next time.

I have studied this problem intensively on the web, it is a complex issue, but it is commonly proposed that uninstalling the AV is a possible solution.
Avast, McAfee, ZoneAlarm and AVG are commonly quoted as being likely conflict programs.

Question ?
Does anybody know if the Avast AV can possibly conflict with the Windows Netio driver and cause these BSOD'S ?

I am damned if I want to uninstall my Avast on a whim.

First, be sure to get rid of all remnants of any prior/other installed AV(s)..!!
-> https://support.avast.com/article/11/

Then:
1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

Thank you Asyn. I will try your proposal after our COVID-19 emergency lockdown has finished. My PC is vital during this period and I cannot risk any problems.
The occasional BSOD I keep getting is highly annoying but tolerable, as the Windows system automatically resolves it, until the next time and off we go again.
