My computer has been very slow lately. I have tried running simple programs from this site to help with virus protection and now my computer is not allowing me to run any antivirus programs, defragmenting or disk clean-up. I can not access system restore at all or program removal; the computer just freezes. I have tried to run it under Safe Mode but this freezes too. I have Windows XP Professional and would appreciate any help I can get.

Some types of malware will target the safe mode registry keys and others used by Windows so you probably have an infection.


Please download TFC (Temp File Cleaner) by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • TFC will clear out all temp folders for all user accounts (temp, IE temp, Java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Note: It is normal for the computer to be slow to boot after running TFC cleaner the first time.

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.Download Link 1
Download Link 2
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. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

I saved the TFC to my desktop but my computer would not allow me to open it. I tried just running it and it
said there was no file association with it, to create one in the Folder Options section of Control Panel ( which I cannot access either.)
Is there anything else I can do?

Some malware infections target .exe files and alter associations. Without repairing the file association ALL .exe files will lose functionality.

If you are unable to run any .exe applications, the first thing to try is to check your file association for .exe files.
  • Go to Control Panel and select Folder Options.
  • Select the File Type tab and click the New button.
  • In File Extension, type: EXE
    Posted Image
  • Click the Advanced button, then from the list select "Application."
    Posted Image
  • Click OK.
  • The EXE extension is automatically selected.
  • Click Restore and close the dialog box.
If you are still unable to run any .exe applications, .com files, please refer to these suggestions:
  • EXE File Association Fix by Doug Knox (xp_exe_fix.zip).
    • Extract (unzip) the file to your Desktop.
    • Double-click on xp_exe_fix.reg and choose "Yes" to merge it into the registry when prompted.
    • Restart the computer and check if you can run an .exe program.
  • Easy File Associations by Doug Knox (fileassoc.txt) to re-associate individual file associations to Windows XP defaults.
    • There is also a link to download a .bat file (xp_fileassoc.zip) which will restore all of the "default" associations in XP.
    • Extract (unzip) it to your Desktop.
    • Double-click on xp_fileassoc.bat and choose "Yes" to merge it into the registry when prompted.
    • Restart the computer and check if you can run an .exe program.
Other Options:CAUTION: Some of these steps involve making changes in the registry. Always back up your registry before making any changes. If you are not familiar with working in the registry, then you should NOT attempt to make any changes on your own. ERUNT is an excellent free tool that allows you to to take a snapshot (backup) of your registry before making changes and restore it when needed.

Pardon me for interrupting here, but would it be possible to make this quoted post by Quietman7 into a sticky somewhere? (if it hasn't already been done)

Bravo, sir. Well done as always. :thumbsup:

It has been several weeks since you last posted a reply. What is the status of your computer now?

BTW, your Malwarebytes Anti-Malware log indicates you are using an outdated database version.
The database shows 4052. Last I checked it was 4356.

Please update it through the program's interface (preferable method) or manually download the definition updates and just double-click on mbam-rules.exe to install. Then perform a new Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Note: Mbam-rules.exe is not updated daily. Another way to get the most current database definitions if you're having problems updating through the program's interface or have already manually downloaded the latest definitions (mbam-rules.exe) shown on this page, is to do the following: Install MBAM on a clean computer, launch the program and update through MBAM's interface. Copy the definitions (rules.ref) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system. If you cannot see the folder, then you may have to Reconfigure Windows to show it.
