Avast has borked my machine
« on: January 03, 2014, 06:54:26 PM »
So, the power went off in the office. I turned on the computer (running XP SP3) and it ran very very slowly. I booted into Safe mode. The computer ran very slowly, but I was able to schedule a ChkDsk.
I rebooted. Chkdsk ran, The Windows logo came up and went to a black screen with an arrow. The hard drive light flickers, but Windows won't load any further.

Went into Safe mode. The OS stopped loading at aswRvrt.sys.

Checked around the Internet, which is how I ended up on this forum. My situtation seems to be a fairly common problem with older versions of Windows + Avast.

I loaded the Recovery console, ran another ChkDsk, which didn't find anything.
I did a search in the System32 folder for all drivers starting with ASW.
I checked that each one of them was used by Avast, and I disabled them via the Recovery Console.

Windows still won't load...same black screen.
Windows in Safe Mode stops at MUP.sys.

I am stumped. I really really don't want to reinstall Windows, but I can't think of anything else to do to get rid of Avast and get my system running again.

To get rid of avast! (completely) run both avastclear and Rejzors uninstall utility. The other instructions mentioned are to do a clean install.

1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition

Note: You need to be ONLINE during this install

Avastclear : http://files.avast.com/iavs9x/avastclear.exe
Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

2. Uninstall Avast by control panel  [If you don't have Avast in control Panel go to #4]
3. Uninstall in safe mode using Avastclear.
4. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn't) - reboot.
Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle.. if so, uninstall it and reboot.
5. Install the version you downloaded.
6. Reboot.

Well, I can't load Safe Mode or Normal Mode Windows. Any other ideas?

Any solution will have to run the Recovery Console.

If the power went down and XP hangs at mup.sys  then it is Windows , not avast that is the issue.

The problem is Avast, because Safe Mode stopped at all the ASWxxx.sys entries until I disabled them.

I also lose the keyboard if I disable aswkbd.sys. What the heck is up with this? The program shouldn't be sitting on my keyboard like that.

Since it is a office system, why not let the admin solve it?

Andrey, that will not work since he can't get windows to boot.

Perform a in-place-repair to make windows work again:

Windows in Safe Mode stops at MUP.sys.

MUP.sys is trying to run chkdsk...

When run in Safe Mode, the last thing you see is MUP.sys being loaded.


EDIT - additional infomation:

It can appear that the computer is "stuck".

If the HDD light is flashing, chkdsk is running...it may take a while to complete.

Eddy, he need to create a bootable cd with OTLPE following the guide and run Farbar Recovery Scan Tool from Reatogo desktop. Of course he need in other PC to create a bootable cd and download FRST.

@sglinert
try to run this command from the command prompt:
Chkdsk c: /r

This will reset the boot data
Then try a reboot to normal windows

Aha. Chkdsk is indeed running. That answers that. Safe Mode loaded to the screen where it says Safe Mode in all four corners, but there's still no desktop. I will let it run overnight. I ran ChkDsk /r from the Recovery Console yesterday in the hopes that it would reset the flag. Obviously, that didn't work.

I also ran a Repair from the Recovery disk yesterday. That did not fix the problem.

That's when I disabled all the ASW drivers in the hope that I could get into Safe Mode.

I will follow these steps...

    Download OTLPENet.exe to your desktop
    Download Farbar Recovery Scan Tool and save it to a flash drive.

Note that Avast on this computer did NOT like the FRST file and tried to abort the download.

And I am the SysAdmin around here.

Thanks for the help. I will return in a while. I want to let Chkdsk finish in the hopes that I can delete Avast from Safe Mode before I try Plan Q.

Okay, I seem to be stuck in ChkDsk Hell. After two days of waiting for ChkDsk to finish and Safe Mode to load, I gave up, inserted the bootable cd with OTLPE...told the machine to boot from the CD...and....ChkDsk started up and is currently preventing anything else from happening. Either that, or the Windows screen I see is actually Windows on my hard drive, and the OTLPE CD doesn't actually boot. I can't test this with another machine. I did download the file and burn it to a CD. Not much else to do there.

Well, try to boot from usb stick.

Download Peazip to the desktop 
Run and install the programme
As it installs this page will show, deselect the AVG ticks
Press decline and it will then install cleanly 
 

 
Download the following files to the desktop .. Right click the links and select save as...then select desktop 
 
Rufus
 
OTLPE_standard
 
Right click OTLPE on your desktop and select  ..Open as archive 
 

 
 
Select OTLPE standard 
 

 
Click Extract, ensure that desktop is selected 
 

 
Insert the USB stick Then run Rufus
 
Select the ISO file on the desktop via the ISO icon.

Press Start Burn


Once the USB has burnt then

  • Download Farbar Recovery Scan Tool and save it to a flash drive.

    • Reboot your system using the boot USB you just created.
    Note : If you do not know how to set your computer to boot from USB follow the steps here

  • As the  Programme needs to detect your hardware and load the operating system, I would recommend a nice cup of tea whilst it loads  :)
  • Your system should now display a Reatogo desktop.
  • run FSRT
  • The tool will start to run.

  • When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.

This file: OTLPEStd.exe

Cannot be opened as an archive. When I right-click, I do not see the option to open as an archive.

PeaZip says it's an executable and can't find anything to extract. It did ask me if I wanted to try a password.

Ah. I see why the CD isn't bootable. I just copied the file to the CD. I didn't try to extract it. But see my previous post. My Win7 machine sees it as an executable file and won't extract anything.
