Cannot Access Windows Update, and experiencing google search redirects.

I was getting BSOD on atapi.sys but only on cold boots, replaced this file from the XP-SP3 cab and the BSOD issue has went away. TDSSkiller shows clean, but the symptoms have not gone away. Please help if possible.

Thanks in advance.

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

Please include a clear description of the problems you're having, along with any steps you may have performed so far.

Please refrain from running tools or applying updates other than those we suggest while we are cleaning up your computer. The reason for this is so we know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process.

Even if you have already provided information about your PC, we need a new log to see what has changed since you originally posted your problem.
We need to create an OTL Report
  1. Please download OTL from one of the following mirrors:
  2. Save it to your desktop.
  3. Double click on the icon on your desktop.
  4. Click the "Scan All Users" checkbox.
  5. In the custom scan box paste the following:
    CODE
    msconfig
    safebootminimal
    activex
    drivers32
    netsvcs
    %SYSTEMDRIVE%\*.exe
    /md5start
    eventlog.dll
    scecli.dll
    netlogon.dll
    cngaudit.dll
    sceclt.dll
    ntelogon.dll
    logevent.dll
    iaStor.sys
    nvstor.sys
    atapi.sys
    IdeChnDr.sys
    viasraid.sys
    AGP440.sys
    vaxscsi.sys
    nvatabus.sys
    viamraid.sys
    nvata.sys
    nvgts.sys
    iastorv.sys
    ViPrt.sys
    eNetHook.dll
    ahcix86.sys
    KR10N.sys
    nvstor32.sys
    ahcix86s.sys
    nvrd32.sys
    symmpi.sys
    adp3132.sys
    mv61xx.sys
    nvraid.sys
    /md5stop
    %systemroot%\*. /mp /s
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\system32\drivers\*.sys /lockedfiles
    %systemroot%\System32\config\*.sav
    %systemroot%\system32\drivers\*.sys /90
  6. Push the button.
  7. Two reports will open, copy and paste them in a reply here:
    • OTL.txt <-- Will be opened
    • Extra.txt<--Will be minimized

In the upper right hand corner of the topic you will see a button called Options. If you click on this in the drop-down menu you can choose Track this topic. I suggest you do this and select Immediate E-Mail notification and click on Proceed. This way you will be advised when we respond to your topic and facilitate the cleaning of your machine.

After 5 days if a topic is not replied to we assume it has been abandoned and it is closed.

Hi,

I would suspect this to be a security program rather than malware. Try disabling your anti virus program and sunbelt and see if the message persists.

If it does, click yes.

Hi,

I would suggest to replace the MBR, however first please create a backup of the current MBR:
First of all I would like you to backup the MBR:
  • Please download mbr.exe and save it to C:\windows <- (Important!).
  • Open NOTEPAD and copy/paste the text in the quotebox below into it:
    CODE
    @ECHO OFF
    CD "%~DP0"
    MBR -c 0 1 backup_mbr.zip
    DEL %0

  • Save this as mbrlook.bat. Choose to "Save type as - All Files" and save it to your Desktop.
    It should look like this:
  • Double click the mbrlook.bat to run it.
  • A file named mbr.zip will be created on your desktop. Please attach that to your next reply.

Once we have the backup of the file, I'll give you the instructions to replace the MBR.

I was going to mention that I just did the fixmbr from the XP install CD recovery shell and the mbr infection is now gone and the system is behaving properly. You had not sent your last message yet when I did the reboot. I am sure that I will need to do some more scans to ensure the computer is completely disinfected. Sorry I jumped the gun but I have been trying to run a java based application for a client that hasn't worked for 2 weeks and I was way overdue. It now works too!

  6. Accept any security warnings from your browser.
  7. Check
  8. Push the Start button.
  9. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  10. When the scan completes, push
  11. Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  12. Push the button.
  13. Push
