My PC stuck even at the safe mode login screen; keyboard and mouse do not work!

Avast Free Antivirus / Premium Security
1

Hi, I’m actually unable to log in my PC after having tried to uninstall your free avast! antivirus with your removal tool and the uninstall feature of windows. My pc stuck at the safe mode log in window? I may not log in to my windows system neither in safe mode. Ty

I’m not following you.
Can’t you login even in Safe Mode?
Which was your antivirus before avast? Seems a huge/deep conflict…

Thank you indeed for your interest :slight_smile:

Yes there was another antivirus: avast! internet security 8.
I: tried to uninstall it with the windows 7 feature in the program applications but nothing happened; I tried to use your uninstall tool, and still no result; I then used revo uninstaller and it seemed to go well.
When I installed the free avast! antivirus I got an error message that told me a dll file from the internet security installation stopped the installation process. I then deleted all of the ocurrences of the registry containing that dll; I retried to install avast! again: another dll error message and subsequent registry deletion. All that happened another one or two times.
In the end I succeed to install the avast! free edition. When I decided to install the avast internet security 2014 trial after removing the free edition I happened almost the same troubles as for the first internet security 8 uninstallation; so after having entered in the f8 boot option (advanced boot options)

I attempted another uninstallation in safe mode but the keyboard stuck at the log on window;
In the advanced boot options I selected the “repair my computer” item:

in the system recovery option window: I tried: “System restore” and “startup repair” with no result.
My last attempt to bypass the window of the safe mode logon where my pc stuck: http://superuser.com/questions/340396/how-do-i-change-automatic-logon-via-script-or-command-line and no result again.
I’m looking for a quick fix before to try to walk all of the longer paths available.

Thank you in advance for all of the help you’ll give me. :slight_smile:

For sure these actions messed things…
Revo is NOT intended to uninstall antivirus and firewalls regardless anything you can read in internet. I also use Revo, never to an integrated tool like antivirus and firewall.
The manual “cleaning” should have removed something necessary to boot.
If you can’t use System Restore I would think the only solution would be reinstall Windows.

Did you ever use this for A/V removal ?..odes not have Avast but seems to have the rest.
I used a long while back to get rid of AVG.

It’s always best to use the vendors uninstaller.
The biggest mistake was messing with the registry.
Like Tech stated…a reformat is in order.

He may be able to do in-place upgrade.

If you happen to get to the registry, you can remove line aswKbd in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}:UpperFilters

Good workaround for the no logon issue is to boot a Live CD of linux (Ubuntu, Linux Mint) and edit your registry from there as above. But only remove this line! Don’t do anything else!

Keyboard and mouse should work just fine in either version of linux.

Thank you a lot for your interest; I accessed the registry of another windows 7 working installation to check the line you mentioned and I did not find it!

Hello, if you mean this: http://www.sevenforums.com/tutorials/3413-repair-install.html it is possible only after having logged on your windows 7 installation. Regards.

You would have to have avast! SafeZone (SandBox) installed to see aswKbd in there. You found the correct key.

13

Well, using a linux Live CD will enable you to recover all your personal files and back them up before you do a fresh clean install.

I 've deleted the key value with this linux application: http://www.pogostick.net/~pnh/ntpasswd/ with no result.

I wonder if there is a way to make a parallel windows 7 installation, in another partition, afterward to merge (extend) some way the not working installation with the working one in order to get again the availability of the files of the first installation in a working windows 7 instance.
Alternatively how to get all of the files and the complete list of installed applications attaching the not working windows 7 disk via USB to my pc?

Thank you.
