Computer won't boot - Safe mode stuck at aswRvrt.sys

Avast Free Antivirus / Premium Security
1

Hello, I have been reading on the forum with people having the same issues as me. I can not boot windows but I can access the Command Prompt. I just ran a FRST scan so I got a logfile which is attached in my following reply.

I would be very grateful for any help.

What happened prior to the non-booting ?

Download the attached fixlist.txt to the same location as FRST
Start FRST and press fix
On completion try a normal boot

Thank you for your quick reply:

Prior to the error, there were 3 things:

  1. I am 80% sure avast did an update. I am 100% sure I updated some windows files using windows update. It asked for a restart but I didn’t, I went to 2) instead.
  2. I did a disk defragmentation, and a chkdsk /r. Right after, or just when I finished the chkdsk, something went wrong as I had to press power button to get away from black frozen screen.
  3. Booted up computer, worked fine for 12 hours. Tried to turn it off, but It without luck, had to force it off by holding in power button again.

Rebooted today, and now the problem described in the title arrised.

I tried your fix, but still have the same problem.New log file:

By the way, I did not create a Bootable USB stick. I did not see any reason for this, since can access the USB stick and run frst64.exe using command prompt.

OK this one will remove all the Avast drivers/services from start… It may not make any difference though

Thank you so much for your help Essex! It worked as I could log into windows! :-). Mark this thread as solved or closed.

I will continue to test out the day, its still freezez from time to time so I am not sure Avast was or is the real problem in the first place.

Is there anything I should run on my computer before I restart for the first time?

You will need to run avast clear and if you wish re-install Avast

Download Avast Uninstall Utility to your Desktop.
Download the correct version of Avast
Avast Free
Avast Pro
Avast Internet Security
Avast Premier
Disconnect from the net
Uninstall Avast via control panel

[]Run the uninstall tool and accept the reboot to safe mode
[]Once complete reboot your system
[*]Reinstall Avast

Thank you.

Crap, so I was able to be in windows for about 30mins. Before I read your post and could install avast uninstall utility, windows crashed and I had to force power button in to restart. Now it wont boot and safe mode stops at classpnp.sys.

Am I forced to format the disc and perform a clean windows install? It would suck due to a deadline that is coming up. I attached the latest log file. Allthough I suspect this is not an avast issue.

As you did a chkdsk I would tend to suspect that it was a windows update at fault

Do you have an image backup at all ?

No I don’t unfortunately. I guess I will have to format. Maybe the hard-drive is gone to pieces as I can not access this drive using my Ubuntu live Bootable USB stick,which should support access to ntfs drives.

If Linux cannot see it then it is dead

The disc shows up under Devices but I can not mount my 500GB partition. I could however mount the System recovery partition, see attached… I get the attached error message. I have currently installed Linux on my SSD disc. Thats where Im working from now.

Try to delete partition I guess? Then see if I can format it. Then reinstall windows on my SSD disc (it was installed on the HDD)

Thanks so much, I promise you I will stop bugging you. And for what it’s worth, I will certaintly remain an avast user after this great support.

That sounds the best bet … Install the OS on the SSD and then probably format the recalcitrant drive
