Download ComboFix from one of these locations:

Link 2

* IMPORTANT !!! Save ComboFix.exe to your Desktop

[*]Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools

[*]Double click on ComboFix.exe & follow the prompts.

[*]As part of it’s process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it’s strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.

[*]Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it’s malware removal procedures.

If you still have problems getting on line then run this

Run OTL

[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:OTL IE - HKU\S-1-5-21-3988870679-946933534-2646707951-1003\Software\Microsoft\Windows\CurrentVersion\Internet Settings: "ProxyEnable" = 1 IE - HKU\S-1-5-21-3988870679-946933534-2646707951-1003\Software\Microsoft\Windows\CurrentVersion\Internet Settings: "ProxyOverride" = ;localhost IE - HKU\S-1-5-21-3988870679-946933534-2646707951-1003\Software\Microsoft\Windows\CurrentVersion\Internet Settings: "ProxyServer" = http=127.0.0.1:8592 O3 - HKU\S-1-5-21-3988870679-946933534-2646707951-1003\..\Toolbar\WebBrowser: (Norton Internet Security) - {0B53EAC3-8D69-4B9E-9B19-A37C9A5676A7} - File not found O4 - HKLM..\Run: [OneCareUI] File not found O4 - HKU\S-1-5-21-3988870679-946933534-2646707951-1003..\Run: [dhedjjwk] File not found

Essex you the man.Thank you very much,ran MBAM and it didnt find anything.My comp is up and running,thank you very much once again,your help is much appreciated.Im assuming its safe to leave combofix and OTL installed

16

Nah lets get rid of my rubbish ;D These programmes are regularly updated

Looking at that I am a happy bunny :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

[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [resethosts] [purity] [emptytemp] [EMPTYFLASH] [CLEARALLRESTOREPOINTS] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

Click Start > Run and copy/paste the following bolded text into the Run box and click OK:

ComboFix /Uninstall

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.

Upgrading Java:

[*]Download the latest version of Java SE Runtime Environment (JRE)JRE 6 Update 23.
[*]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-6u23-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-6u23-windows-i586-p.exe and select “Run as an Administrator.”)

SPRING CLEAN

Download and run Puran Disc Defragmenter
For the first run I would recommend a boot defrag and disk check

http://i1224.photobucket.com/albums/ee362/Essexboy3/Bootdefrag.jpg

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

http://img233.imageshack.us/img233/7729/mbamicontw5.gif
Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

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
[*]Microsoft Windows Update

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:

Java is a pain - I get more problems on updating this than anything else

OK easy way first

Please download JavaRa to your desktop and unzip it to its own folder

[*]Run JavaRa.exe, pick the language of your choice and click Select. Then click Remove Older Versions.

[]Reboot and then try the installer again
