I have a Windows XP and I use Norton as a firewall and in the last week or so Firefox has been abruptly closing, most of the time the pop-up about "experiencing a problem and needing to close" comes up first, but sometimes it just closes without warning. It seems random, but especially bad when I'm trying to watch a video. Not sure if that means something.

So, I figured there was a virus and tried running a full system scan with Norton, but no viruses were found.
I then tried to run a full system scan with Ad-Aware and Spybot Search and Destroy, but no viruses were found with either.

I then tried uninstalling and reinstalling Firefox, but still it kept shutting down.
I also open Internet Explorer and noticed that it would shut down as well.

I then tried to do a system restore, but after my computer restarted it said it could not complete the process. I tried again and I noticed as it was shutting down (before it started restoring) several error messages quickly popped up. I wasn't able to see what they said, but if this information is pertinent, I can do this several more times so I can try and copy them.

So, now I'm out of ideas as to what I can do with my limited understanding of computers. I would appreciate any advice or help. I know this isn't a lot of information about the problem, but I don't know anything about what the problem is. All I know is Firefox keeps shutting down and the virus scanners are telling me my computer is clean so... I'm not really sure here.

Hello and welcome please run these next. Since you have Spybot installed temporarily disable it.

Next run ATF:
Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".


Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

My computer just randomly shut down, without warning and without going through the shut down process and it the proceeded to restart on its own.

When it reloaded an error message popped up and said:

"The system has recovered from a serious error

A log of this error has been created.

Please tell Microsoft about this problem.
We have created an error report that you can send to help up improve Microsoft Windows. We will treat this report as confidential and anonymous."

I'm not going to post any of the details of the report here, because according to that, it involved my IP address... ? I'm sorry it's way beyond my realm of understanding. Anyway, I thought I should include this error message incase it had anything to do with Firefox crashing or a certain virus, etc.

Has this been the only shut down now? I am hoping the malware ha not corrupted the registry too severely. Can you post that report and edit out your IP address?

My boyfriend said my computer randomly shut down like this a few days ago, but I just assumed the power flicked off. He said a message popped up but he didn't click to get the extra information. So, this was all before Malware was used.

The information the error message gave me was just a bunch of code and it didn't say what it meant, just that it could be sent in to Microsoft. But, I'm also confused why they explained in the error message about my IP address because it's not anywhere in the code. So I will include what the code says and not leave anything out.

BCCode: 1000007E
BCP1: C0000005
BCP2: EE7ECD83
BCP3: EE9ADBF8
BCP4: EE9AD8F4
OS Ver: S_1_2600
SP: 3_0
Product: 768_1

There were also a few sentences following this about sending this information to Microsoft, safety, etc., but I wasn't able to copy them down.

Hello I just did a bunch of research and I would suspect it to be a Power supply problem starting. I think you should copy that last post into a new topic in the XP forum. One of the Staff there will read that code better than I.

I'll do that and thanks for all your help! Although, I'm still having problems with Firefox shutting down. Do you think it's related to the computer shutting off/power supply problem or something else?

I think its related but not 100% sure. Let them see the codes and they will ask you better questions. Mention the Firefox issue too.
