ntoskrnl.exe Error, need this fix by tomorrow morning

Viruses and worms
1

Hello, let me just say that I have been a big fan of the Avast Anti-Virus software and I have recommended it to all my friends and clients. I am a rookie IT repair man, and lately I’ve been fixing up laptops, most notably optimizing Windows. Most of my clients have slow performances due to infections however, my only solution has only been a full system restore. Currently is there a way to fix ntoskrnl.exe? I used aswMBR.exe and it detected this in my clients Windows 7 laptop. Let me provide the official log

Now I’ll post the OTL logs soon

4

Once you have attached the OTL log then re-run TDSSKiller with the same parameters
When this element appears select delete :

\Device\Harddisk0\DR0 ( TDSS File System )

5

Edit: NVM, well here are the logs

6

There will be some delay due to differing time zones (almost 1:30am in the UK) and essexboy will be sleeping. But he should be back later today to continue.

7

I would recommend a run with AdwCleaner as there is a lot of rubbish there

How is the computer at the moment

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL

So far, so good. The computer speed has increased and a lot of the junk webpages are all gone so browsing performance has increased.

Subject to no further problems :slight_smile:

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:

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.

: 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 and 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)
