Recently, I have had a problem with windows explorer closing down every time I try to open a removable drive from My Computer. A message pops up saying that Windows Explorer encountered an error and needs to close. Prior to this, I received a warning from Norton saying that a program had modified 2 registry keys. Threatfire asked me if I wanted to allow this program to run and I terminated it, but since then I keep running into the problem with windows explorer. It has also slowed my computer down somewhat.

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • 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.
  • 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 you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

Reboot your computer, run the Malwarebytes Full Scan and post the new log.

Well, the computer is back up to its normal operating speed, but occasionally I am still getting the Windows Explorer error. For some weird reason, this only happens when I try to access a flash drive, when I access my external hard drive, it works fine. There are sometimes when I don't get the error, and some times I do. It looks like it only happens when I try to open a file on the flash drive. I also get a message about Dr Watson Postmortem Debugger having encountered a problem.

Have a look in the Event Viewer for any errors at the time of the Windows Explorer error.

To open the Event Viewer go to Start > Control Panel > Administrative Tools > Event Viewer. Alternately, go to Start > Run and type in "eventvwr.msc" (without the quotes) and press Enter.

Check in all the categories.

If you find an error that occurred at the time right-click on it and select properties. Copy the information in the window and post it back here. This will help us diagnose your problem.

Try running the System File Checker.

Everything seems to be working now. I ran the program, and said Cancel every time it asked for a SP3 CD. After that, I was able to open files on my flash drives. I think the corrupted files were overwritten with original data. Thanks for the help :thumbsup:

Actually, hitting cancel all the time is not the way to run the System File Checker - but if your problem is resolved I'm not going to argue with you :thumbsup:

You are right, and the problem cropped up again. I'm going to try the same process, but this time using the disk. Could I create a SP3 disk in the same way as the SP2 disk was made? I have to original XP disk, but it asks for the XP SP3 disk.

By the way, how can I use the i386 folder on my hard drive instead of the disk, because all I have is the Recovery Disk that came with the computer. The disk has an i386 folder as well.
