Hi,

Thanks in advance for your attention and help.

I'm running Windows XP SP2 on my Lenovo T61, with Norton AV and Spybot SD for active virus/malware protection. For the last few days, my system has been horribly unstable - with IE crashing frequently (was happening with IE7 and continues to happen with IE8) or the machine freezing up completely (I have to end up doing a power down). Here's a brief history of what's been going on:

1. Started with IE acting up strangely after a particular browsing session. I was suspicious, therefore downloaded and ran Malwarebytes which found 5 infections that it tried to remove and clean. If required, I may have a log from this original scan that I can put up.

2. The machine became extremely unstable in normal mode and I resorted to just running things in safe mode, hoping it would be better. Ran MAB again and it found 3 infections - presumably leftover from the previous scan that it was unable to remove. The constant was a "backdoor.bot". After a few scans and re-starts, it seems to have been able to remove the offenders - I see no infections now through a full scan of MAB and MSRT on either normal or safe modes.

3. However, other things that were previously working have started to come apart. On booting up, I would get an application error (could not write to memory location) for AcSvc.exe. Reading up on a few forums I gathered I needed to update IBM's Access Connection Service and went ahead and did so from IBM's website. With the latest version installed I no longer get this error message, but am concerned about how / why this started happening in the first place.

4. In conjunction with the above message, my wireless adapter/connection started acting strangely. At first, it began with IE not recognizing that I was connected to the Internet when on wireless. I use Lotus Notes as my mail client and it had no problem sending/receiving email, but IE would not detect I was connected to the internet even though I was. Since then, it progressed to IE simply freezing up anytime I tried accessing a web-page while connected to the wireless. A wired connection worked fine.

5. I updated my Intel wireless pro drivers again from the IBM / Lenovo website and it seemed to solve the problem initially - at least I was able to use the wireless connection and IE recognized that I was connected to the internet. This lasted about 10 minutes though and I seem to be back to square one with IE crashing if I try accessing over wireless. The other thing I can relay is that my wireless LED is constantly ON - doesn't blink or anything, its just on. Not sure if this should be the case or not.

6. Even on a wired connection, about 5 minutes of use of IE causes either IE to crash or the system to freeze. I've seen the blue screen of death a few times and all errors seem to be related to "unable to write to memory location" type of errors. If instructed on how to do so, I could post back with information from such a crash when it happens next.

I'm at wits end and am looking forward to your help in resolving these issues. Even though MAB gives me a clean chit, I'm not sure if the machine is clean. Or, trying to clean it has broken something in the OS.

Thanks.

:trumpet:

I wonder if you CAN locate the report from the Malwarebytes program for review?

The log is ( should be!!) automatically saved and can be viewed by clicking the Logs tab in MBAM.
Please copy and paste the contents of that report for us to have a look see :thumbsup:

I hope you have NOT got what is called a 'Back- door 'infection on there :flowers:

I just finished running the two scans. SuperAntiSpyware found 1 compromised registry entry and MAB found nothing. The two logs are pasted below. Since I've just completed scanning the system per your instructions, I can't comment yet on whether things have improved or not - I will post back after a couple of hours of use.

Well this looks pretty good now. What symptoms if any are left?

Hi,

Thanks for working your magic, over the last 12 hours of use the system has functioned almost perfectly. I haven't yet used a browser other than IE, but given that IE was the one causing the machine to crash most frequently I think its safe to say the major underlying problem seems to have been corrected. Again - thanks VERY much! Curious to know what it was you found and fixed.

Now, one issue remains. Not sure if this was there earlier as I wasn't booting into Normal Mode often enough with the infection. When I boot into normal mode now, a dialog box appears stating it could not find "HIDEC.exe". The path indicates this is related to ComboFix - which is installed on my machine and was used as a fixing tool for an earlier attempt at removing malware. Is there a way to get rid of this?

I uninstalled ComboFix, but as the message continues to appear am pasting below the registry entries I found using Registrar Registry Manager corresponding to "HIDEC.exe". Anything you can recommend to get rid of this message?

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\PEVSystemStart
ImagePath
cmd /k start /i "/d%systemdrive%" "C:\ComboFix\HIDEC.exe" "C:\WINDOWS\system32\CF8660.exe" /c RD /S/Q \$RECYCLE.bin \RECYCLER \RECYCLED

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\PEVSystemStart
ImagePath
cmd /k start /i "/d%systemdrive%" "C:\ComboFix\HIDEC.exe" "C:\WINDOWS\system32\CF8660.exe" /c RD /S/Q \$RECYCLE.bin \RECYCLER \RECYCLED

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PEVSystemStart
ImagePath
cmd /k start /i "/d%systemdrive%" "C:\ComboFix\HIDEC.exe" "C:\WINDOWS\system32\CF8660.exe" /c RD /S/Q \$RECYCLE.bin \RECYCLER \RECYCLED


In addition I have a few observations / questions:

a) With SuperAntiSpyware now installed, I now have the following running on start-up : Norton AV, Spybot SD and SuperAntiSpyware. Is this a recommended setup? Would Spybot/SAS conflict with each other?

:thumbsup: Though IE has been stable, it feels slower / clunkier for some reason. New tabs take a while to appear, the text I'm typing currently into this box lags by a few characters etc. This isn't a critical issue at all.

Thanks again for getting the system back to being stable. I had resigned myself to the idea of having to do a format / OS re-install. Look forward to your help in now removing the above minor annoyance.

Hello,good news and you are welcome..


Its not unusual to receive such an error after using specialized fix tools.

A "Cannot find...", "Could not run...", "Error loading... or "specific module could not be found" message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.

Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this.)
Open the folder and double-click on autoruns.exe to launch it.
Please be patient as it scans and populates the entries.
When done scanning, it will say Ready at the bottom.
Scroll through the list and look for a startup entry related to the file(s) in the error message.
Right-click on the entry and choose delete.
Reboot your computer and see if the startup error returns.

******************
Remove Combofix now that we're done with it.
Click on your Start Menu, then Run....
Now type combofix /u in the runbox and click OK. Notice the space between the "x" and "/".


When shown the disclaimer, Select "2"
This will remove files/folders assoicated with combofix and uninstall it.
*******************

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.


You should remove either SAS or spybot as threy are using system resources at start up.
