Unable to start Windows after Avast reinstall (logs attached).

After creating a Linux bootable USB, I noticed that at start up I got an error message from avastui.exe “The application was unable to start correctly (0xc0000005) Click Ok to close the application.”

The creation of the bootable USB might have had nothing to do with it and was probably just a coincidence.

To fix the issue, I reinstalled Avast.

Later when I tried to install mirc, I got an error message that it could not complete the installation. I thought “hmm weird”…and restarted the computer.

At the “Windows starting” screen, it went back to restart, showing me the recovery menu screen.

I selected safe mode but it would still not start…but rather still goes back to the recovery menu.

I noticed during the drivers load list when attempting to start at safe mode, it stops at \windows\system32\drivers\Aswardisk.sys before restarting (boot loop).

Another thing to note is a momentary, split second flicker of BSOD right after the Windows starting screen before proceeding to restart - a detail also mentioned here, in this post, https://forum.avast.com/index.php?topic=180082.msg1558103#msg1558103, which describes my exact problem.

Things I’ve tried to remedy this issue:

  • Last known configuration (advanced).

  • Startup repair through Windows installation disc. (No restore points so couldn’t do that).

  • Booted through Linux live USB and deleted the Avast folder in programs folder.

  • “chkdsk: c: /r” (I get “failed to transfer logged messages status 50 superuser” at the end but it says no problems found).

  • I’ve renamed aswardisk.sys to aswardisk.sysa (sort of following the reported solution here —>https://forum.avast.com/index.php?topic=225528.15.
    Upon doing so, the drivers load list passed aswardisk.sys but then got stuck on another driver - aswbidsh.sys. So i did the same with that file (and aswbuniv.sys, aswRvrt.sys, aswVmm.sys) as well. Doing so allowed the load to pass all these files but get stuck on disk.sys. So i did the same, renamed it. Then it was another file - classpnp.sys. This is where i stopped renaming .sys files.

None of the above methods changed anything, obviously.

Could someone PLEASE help? Needless to say, I don’t want to do a clean install because I need my files.

Thank you so much!

This place is absolutely useless. Cursed is the day that I installed Avast.
