    Hi and welcome,

    Please post your Hijackthis log directly into the thread next time instead of as an attachment please. Thanks.

    Create a folder named HJT such as C:\HJT and put your HJT into this folder please.

    Please get these two spyware programs if you don't already have them.

    SpyBotS&D

    AdawareSE


    Reboot between scans and after last scan



    There is a new and improved version of AdAware that you need to have installed on your computer. The new version is AdAware SE
    If you have AdAware already installed on your system and it's NOT SE go to your Control Panel and click on Add/Remove Programs. Click on AdAware and then REMOVE and then just complete the removal process.

    Once it's un-installed download the FREE version of AdAware SE. Once it's downloaded double click on the new file to start the install process.
    Click Next>I accept>Next>Next> then be sure and put a dot in the bullet for Anyone Who uses this computer and then click Next>Next>

    In the next dialog box remove the dot in the bullets "Start Scan" and also "Launch Help Files" and click Finish

    Now if the program doesn't launch double click on the icon that should now be on your desktop to start AdAware SE

    Now click on the button for Check for Updates
    If updates are found click on the OK button and after it downloads to 100% click on the Finish button.

    Click the Start Button
    Click on the link for Customize
    in the Main Window under Scan Settings
    click on the red X in front of Scan within archives to change it to a green check

    Then click on the button on the left labeled Advanced
    click on the red X in front of Move deleted files to Recycle Bin to change it to a green check
    click on the red X in front of Include Environment Information to change it to a green check

    Then click on the button on the left labeled Defaults
    click on the Read current settings from system

    Then click on the button on the left labeled Tweak
    Click on the (+) in front of Scanning Engine to expand the group
    click on the red X in front of Obtain Command line of scanned processes to change it to a green check

    click on the red X in front of Reanalyze results after scanning . . . to change it to a green check
    click on the red X in front of Write protect system files after repair to change it to a green check

    Click on the (+) in front of Log File to expand the group
    click on the red X Create Log File for removal operations to change it to a green check

    Click on the (+) in front of User Interface to expand the group
    click on the red X Remember window positions to change it to a green check
    click on the red X Snap windows to desktop borders to change it to a green check
    click on the red X Use gridlines in results list to change it to a green check

    Click on the (+) in front of Web Update Settings to expand the group
    click on the red X Create and save WebUpdate log file to change it to a green check

    Click on the (+) in front of Misc settings to expand the group
    click on the red X Dump details about unhandled exceptions to disk to change it to a green check


    Then click on the button at the bottom right labeled Proceed then click the Next button to start scanning.

    Once the scan is complete you'll have a flashing Bug and a brief sound to indicate scanning is complete and Adware is found. Click on the Next and then click on each of the empty boxes to the left of the found items under SCAN SUMMARY. Then hit the Next button. Then OK. This should clean your system of all the found nasties. When it's complete simply close the program until your next scan session. Always ALWAYS check for updates before very scan.
    # Reboot
    # Post us a fresh HijackThis log afterwards


    Run the scans rebooting between scans and after last scan and post a new Highjackthis log please. Info for Hijackthis at below link. Thanks.

    Neal, many thanks. I already had AdawareSE installed - I have updated to the latest sig file and implemented all of teh options you suggest. have rerun hijack program and re-attached log (have to do ot this way as problem PC won't conect to teh Internet via a browser).

    Problem PC is much better but iexplore wont connect to teh internet - always get "Page can't be displayed" - although I am able to ping the web sites and Panda etc can download files. Also, PC is still running very hot.

    Any help much appreciated.

    HI,

    As far as the temperature that sounds like a fan/cooling problem which would require someone going inside your computer and replaceing it.

    If you have to you can burn these fix programs to disk or floppy and bring them to your computer from an uninfected computer.

    Make sure you can see hidden files.
    In Windows XP
    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 Show hidden files and folders.
    Uncheck the Hide protected operating system files (recommended) option.
    Click Yes to confirm.
    Click OK.
    After you're cleaned, please "rehide" them again.


    Next,
    Download the Intermute stand-alone version of CWShredder from here: cwshredder.net/bin/CWShredder.exe
    Install it and check for updates then exit, we will use it later.

    Next,
    Please download CWShredder from here( this is the older version), then exit no run yet http://www.thatcomputerguy.us/downloads-cat4.html



    Download About:Buster from here:

    www.besttechie.net/tools/AboutBuster5.zip

    Or here:

    www.malwarebytes.biz/AboutBuster5.zip

    Or here:

    http://majorgeeks.com/download4289.html


    Unzip it to its own DESKTOP folder, right click open area on the desktop, click new, the new folder, name the folder Aboutbuster . It is VITAL that it be unzipped.

    Please open/run the program and check for updates. After you update it exit.
    Do not run the actual scan/fix until instructed below.

    Disconnect from the internet, pull the wire unscrew the cable what ever you have to do to not have any physical connection to the computer


    Scan with Hijackthis again and put a check next to these items and making sure all browser windows are closed before clicking fix.

    R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = about:blank
    R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = res://C:\WINDOWS\system32\nbzbg.dll/sp.html#83556
    R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Bar = res://C:\WINDOWS\system32\nbzbg.dll/sp.html#83556
    R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = res://C:\WINDOWS\system32\nbzbg.dll/sp.html#83556
    R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page =
    R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = res://C:\WINDOWS\system32\nbzbg.dll/sp.html#83556
    R3 - Default URLSearchHook is missing

    O2 - BHO: Class - {137D9D58-DEAC-510D-3DD5-BE1236A710B2} - C:\WINDOWS\apigp.dll (file missing)

    O3 - Toolbar: (no name) - {BA52B914-B692-46c4-B683-905236F6F655} - (no file)



    Again make sure all browser windows are closed and click FIX


    Now reboot into safe mode by tapping your F8 key upon restart and safe mode screen appears, select safe mode and press enter.


    Now, run About:Buster at least 3 or 4 times.



    Next, run both CWShredder
    -Click on the: ‘Fix’ Button on the first one and let it run, then click on fix for the second one and let it finish.
    -Follow the prompts, and press OK


    Now navigate to these file(s) thru WINDOWS EXPLORER and delete them please: If Found

    C:\WINDOWS\system32\nbzbg.dll

    It is recommended that you do a couple of things after a serious infection.

    Just to be sure.


    Go to Start > Run and type: CLEANMGR.EXE and hit enter.
    When prompted select the C: drive and click ok.
    Check the boxes for:
    Temporary Internet Files
    Downloaded Program Files
    Recycle Bin
    Temporary Files
    Click OK or Enter

    Make sure you are set to normal startup. Click Start -> Run -> Type Msconfig -> Press Enter -> make sure Startup is set to Normal Start


    Post a new HJT log for further review

    One other thing:

    Why don't you download Firefox browser and use it thru this fix and maybe that will help. Burn it to disk if you have to.

    Firefox download page:---www.mozilla.org/products/firefox/


    It's more secure then IE anyway, you can switch back and forth as I do.

    And it is uninstallable thru add/remove programs.

    It will not take very long to download at least it didn't own my machine.

    Save 20% on AVG Internet Security 2012 Suite!
    That might be a good idea, let me look at a new HJT log.

    You might have a winsock/LSP problem we can fix easily.

    Then again maybe not.
