One question:

The Nethwork profiles of the Avast Firewal near the MAC-adress must it set to private or public if it is connected to the Internet?
One is the router and they other is the computer MAC-adress.

It should be to private on a home network..  The minidumps are inconclusive they reference no drivers or file

Hi @essexboy,

Thank you for checking the dump files.

De computer works fine now. All the Windows updates were successful.
Also Avast Firewall is works good.  :)

I have the Chrome browser configured so that no longer Yahoo searchpage appears.

There is one problem that worries me.
Both browsers, Internet Explorer and Chrome wants to download an older version (3.1)  of Fire Fox.

I type the adress https://www.mozilla.org and than choose the download link on their website.  And then the wrong version is offered.

The Laptop computer Win 8.1, download the right version FF 4.4.

Have you any idea how this could happen? What can we do about this? Is it a router problem?

There is already a Fire Fox install, but wich can not be started, error Couldn't load XPCOM.
We can not uninstall it through control panel, Programs, because there is no uninstall there.
In uninstalle in the map C:\Program Files\Mozilla Firefox\uninstall\helper.exe, does not work.

Thank you for taking your time to help us.

Delete the entire FireFox folder.
Remove all registry entries that FireFox is using.
Reboot
Download and install the latest version.

@essexboy,
Today there were computer problems.

An overview:

- Yesterday we have remove in the Program Files the map WinZip (empty) and the  Family Toolbars to the Bin.
- Then reboot the computer
- The computer starts fine
- Change the setting of the Chrome browser
- Try to download Fire Fox with IE which we stopped.
- We have tried te start the Fire Fox from the desktop, but it does not start. Also de uninstall does not work (see post before)
- Shut down the computer, and it is going well.

Today, around half past 7 pm starts the computer with the error "the computer is not properly closed', and begins a Startup Repair.
Then we were on the desktopscreen and the mouse cursor frozen for a view minutes. Suddenly a black screen and than a blue screen of death. That was about 5 minutes after the Startup Repair.

So the system is not stable yet.

Do you still have options for this problems?

Here are a new mini dump file.

Does this happen regularly   ?   As if it is random it will be very hard to track down

For firefox, use Revo uninstaller to remove it prior to installing a fresh copy

@Eddy,
Thanks for you advice, yes the whole Fire Fox must delete.

@essexboy,

Does this happen regularly?   As if it is random it will be very hard to track down
No, it is random, and it is not happend again. So we leave it that way. It is a 9 year old computer  :)

I have try to remove Fire Fox with Revo Uninstaller Free, but which was unable to do the job.
 
I downloaded the Revo Uninstaller Pro, and used the option Forced Uninstall and pointed it to the folder Mozilla Fire Fox and also other related folders.
They used a logfile and than deleted the whole FF. I Used the Advanced option to clean all de windows registry keys.

Then we do a clean install of FF 4.4. There appears a startpage from Malware bytes with warnings and advice.

We have used the Revo Unistaller Pro als to delete the folders Yahoo Search and more folders in the Program Files.
 
The computer is now much faster and more pleasant to work with. No more crashes have happened.

All looks good now en we very happy about this!

One thing: how do we get a good Java program?

Thanks to your help and time, we now have a clean computer.

Thank you very much!  :) :) :)

Subject to no further problems   :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:


Remove tools

Download and run Delfix
Select the options as shown



: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article

I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)

If you do need to keep Java then download JavaRa
Run the programme and select  Remove Java Runtime.  Uninstall all versions of Java present
Once done then run it again and select Update Java runtime > Download and install Latest version



Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

CryptoPrevent install this programme to lock down and prevent crypto ransome ware



Malwarebytes

Update and run weekly to keep your system clean

Unchecky

Click on the link above to be taken to Unchecky.com
click the very large Download button.
click Save
Click Open folder
Right click on the Unchecky_setup and choose to Run as Administrator
Once open click the Install button.
Then click on Finish
Unchecky is now installed and will help you keep unwanted check boxes unchecked, this is a fire and forget programme  ;)

It is critical to have both a firewall and anti virus to protect your system and to keep them updated.
