Hello,
I know this is a problem repeated many times, yet I can not solve it.
I'm running Windows XP Pro. I have Kaspersky as my anti-virus/firewall.
Windows and Kaspersky are all up to date.
I've turned off all Performance Logs and Alerts. Rebooted, and still can not delete.
I do share my computer with my son, so I'm not sure of everywhere he visits on the internet.
I put all my computer equipment details in my profile, if that helps anyone.
I've read about ComboFix, but do not dare mess with something that seems (to me) to be very powerful without any expert help.
I'd appreciate any help in this matter of removing this file and seeing what I can do about preventing it from returning.
I clean out my temp files and "tracks" daily, so seeing this little bugger drives me nuts.
Thanks in advance.

Please submit the file for a Jotti scan

"File is empty (0 bytes)!" is what it said.
Also, the name changed since yesterday, it is now "Perflib_Perfdata_4b0"

Now it's creating addition files like this: cch~c9456f110f2.htp

Those "....htp" files were scan with the same result "File is empty".

Let's try a few things before I move you onto Hijack This




The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

I ran the quick scan and it didn't find any malicious software. I then ran the in-depth scan with the same results.

I could recommend a couple of different ways to delete it but without knowing what it is I am hesitant
Let me check with some others


While I do that run


SAS,may take a long time to scan
Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.

Do you have any idea what is supposedly writing a log? Have you installed any new programs or updated them

Have you tried going in to safe mode to delete them
Maybe you have to take ownership:
http://support.microsoft.com/kb/308421

Mbam has File Assassin


MBAM has a built-in FileAssassin feature for removing stubborn malware or other malicious files that it did not detect.
  • Go to the "More Tools" tab and click on the "Run Tool" button
  • Browse to the location of the file (C:\xxxx.exe) to remove using the drop down box next to "Look in:" at the top.
  • When you find the file(s), click "Open".
  • You will be prompted with a message warning: This file will be permanently deleted. Are you sure you want to continue?. Click Yes.
  • If removal did not require a reboot, you will receive a message indicating the file was deleted successfully, however, I recommend you reboot anyway.

Caution: Be careful what you delete. FileAssassin is a powerful program, designed to move highly persistent files. Using it incorrectly could lead to serious problems with your operating system.


If the file returns, then you probably still have malware on your system which is protecting or regenerating it.

One of our HJT team members provided this information


Go to your Windows temp. folder and find the file.
Right-click on the file and select Properties, then Security, then Advanced

Change the owner to administrator and replace on all sub containers. Apply it, OK it and close the properties box. Add the admin group with full permissions...When adding admin group permissions check the box for applying to all child objects. Remove the check for inherit permissions

You should then be able to delete them without any problems
