Title: Avast UNEXPECTED_KERNEL_MODE_TRAP ntoskrnl.exe
Post by: Brannyt2000 on March 11, 2021, 02:15:39 PM

Hi,

So when Avast almost finishes installing I get a BSOD which says UNEXPECTED_KERNEL_MODE_TRAP. This BSOD happens every single time I turn on my pc and I have to restore to a previous restore point just to access windows. I know for a fact that it is something to do with Avast because the issue is fixed when I either uninstall avast or revert to a previous restore point.

I tried installing Avast in safe mode which worked but as soon as I restarted my PC I had BSOD again. I have even tried installing Avast on a completely fresh copy of windows as I thought it may have been another driver affecting Avast for whatever reason.

If anyone could help it would be much appreciated

Thanks

I forgot to mention that I have had this issue on a previous computer but it wasn't nearly as bad. I would get the same BSOD once a day but I could still access windows.

- Which Avast..? (Free/Premium)
- Which version/build of Avast..?
- OS..? (32/64 Bit..? - which SP/Build..?)
- Other security related software installed..?
- Which AV(s) did you use before Avast..?

I have had to reinstall windows as I was getting constant UNEXPECTED_KERNEL_MODE_TRAP and CRITICAL_PROCESS_DIED. IT had corrupted my windows and its restore points.

To answer your questions, I was fully up to date with windows (64bit) and I used the premium trial and regular Avast that you can download off the website but I cant check now what specific version I was running. I had not used any other AV software before.
