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..Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself.  MBAM can be uninstalled via control panel add/remove along with ERUNT.  But they may be useful tools to keep

We will now confirm that your hidden files are set to that, as some of the tools I use will change that
  • Click Start.
  • 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.
  • Click OK.

   Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system. Please follow these steps to remove older version of Java components and upgrade the application. Beware it is NOT supported for use in 9x or ME and probably will not install in those systems

Upgrading Java:
  • Download the latest version of Java SE Runtime Environment (JRE)JRE 6 Update 19.
  • Click the "Download" button to the right.
  • Select your Platform and check the box that says: "I agree to the Java SE Runtime Environment 6 License Agreement.".
  • Click on Continue.
  • Click on the link to download Windows Offline Installation (jre-6u19-windows-i586-p.exe) and save it to your desktop. Do NOT use the Sun Download Manager..
  • Close any programs you may have running - especially your web browser.
  • Go to Start > Control Panel, double-click on Add/Remove programs and remove all older versions of Java.
  • Check any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button.
  • Repeat as many times as necessary to remove each Java version.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on the download to install the newest version.(Vista users, right click on the jre-6u19-windows-i586-p.exe and select "Run as an Administrator.")
XP
Now to get you off to a good start we will clean your restore points so that all the bad stuff is gone for good. Then if you need to restore at some stage you will be clean. There are several ways to reset your restore points, but this is my method:
  • Select Start > All Programs > Accessories > System tools > System Restore.
  • On the dialogue box that appears select Create a Restore Point
  • Click NEXT
  • Enter a name e.g. Clean
  • Click CREATE
You now have a clean restore point, to get rid of the bad ones:
  • Select Start > All Programs > Accessories > System tools > Disk Cleanup.
  • In the Drop down box that appears select your main drive e.g. C
  • Click OK
  • The System will do some calculation and the display a dialogue box with TABS
  • Select the More Options Tab.
  • At the bottom will be a system restore box with a CLEANUP button click this
  • Accept the Warning and select OK again, the program will close and you are done
VISTA
To manually create a new Restore Point
  • Go to Control Panel and select System and Maintenance
  • Select System
  • On the left select Advance System Settings and accept the warning if you get one
  • Select System Protection Tab
  • Select Create at the bottom
  • Type in a name i.e. Clean
  • Select Create
Now we can purge the infected ones
  • Go back to the System and Maintenance page
  • Select Performance Information and Tools
  • On the left select Open Disk Cleanup
  • Select Files from all users and accept the warning if you get one
  • In the drop down box select your main drive i.e. C
  • For a few moments the system will make some calculations
  • Select the More Options tab
  • In the System Restore and Shadow Backups select Clean up
  • Select Delete on the pop up
  • Select OK
  • Select Delete
You are now done

SPRING CLEAN
 
Download TFC to your desktop
  • Open the file and close any other windows.
  • It will close all programs itself when run, make sure to let it run uninterrupted.
  • Click the Start button to begin the process. The program should not take long to finish its job
  • Once its finished it should reboot your machine, if not, do this yourself to ensure a complete clean
THEN

Download Flush Flash from Here and follow the easy to use instructions on the same page

NEXT

Download and run Puran Disc Defragmenter

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes: It is critical to have both a firewall and anti virus to protect your system and to keep them updated.

To keep your operating system up to date visit To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?
Keep safe  :wave:

Two quick questions before I begin Essexboy:

1. What about the files which Combofix quarantined on the first run? (please see below)

2. Will these steps also remove Combofix?

Thanks!

What about the lmhosts file in the System32? Was that a bad file? If not, does it need to be restored?

Are the .tmp files from the IE directory only temporary files that don't matter? Were they bad?

Thank you Essexboy.

Lmhosts is only used for and by network admins, there is no need for it on a standalone system.  More info here   http://support.microsoft.com/kb/314108  and it is used by malware

The temp files were suspect and quarantined as a matter of course, but nothing important will be in those temp files

Thanks Essexboy. I have completed all steps up to and including the TFC step in your instructions.

It completed successfully and asked for a reboot. Just before the computer shut down, a dreaded Windows blue screen appeared.

The computer rebooted successfully. The only difference was a box from Microsoft which stated 'the system has recovered from a serious error. Send or Don't Send report'. I clicked don't send.

Is this bad?

Do I proceed with the next step (flash flush)?

Obviously one of your drivers got a bit miffed at being force closed, it is not a problem

Continue the steps

Hi Essexboy,

I have completed all of your steps (except for the Java upgrade as I already had Java RE Version 6 Update 20.

My computer rebooted normally so I assume that my computer is clean!

Thank you SO much for your time, patience and continued support. Hopefully you will buy a lottery ticket this week and win the jackpot! You definitely deserve it!

Cheers and enjoy the rest of the weekend,

Avastfan1
