Possible Malware?

[hoorock]

Hi folks. I've been having a lot of problems with my Firefox browser on my home machine. It seems to lock and close every few minutes. After doing the Firefox-recommended troubleshooting (run in safe mode, reinstall, remove add-ons, etc.) I'm still experiencing the issue. And its only on my home machine, leading me to think something might be lurking on the PC. I have run new ad-aware scans, but that didn't turn up much.

I thought I'd give you guys a try to see if, in fact, I do have something hanging out in my machine. Thanks in advance for your help.

Here is my log file from "hijack this".

Hi,hoorock, and welcome to malwareremoval forums

I'm dan12, I'll be glad to help you with your computer problems.

Please observe these rules while we work:

• Perform all actions in the order given.
• If you don't know, stop and ask! Don't keep going on.
• Please reply to this thread. Do not start a new topic.
• Stick with it till you're given the all clear.
• REMEMBER, ABSENCE OF SYMPTOMS DOES NOT MEAN THE INFECTION IS ALL GONE.

If you can do these things, everything should go smoothly.

• Please note you'll need to have Administrator priviledges to perform the fixes. (XP accounts are Administrator by default)
• Please let me know if you are using a computer with multiple accounts, as this can affect the instructions given.

It may be helpful to you to print out or take a copy of any instructions given, as sometimes it is necessary to go offline and you will lose access to them.

I'm presently looking over your log and hope not to be too long.
Will be back with you as soon as I can.
Thanks dan

[dan12]

Submit a file to Jotti
Please go here : http://virusscan.jotti.org/
On top of the page there is a field to add the filepath,browse and find the file click open which will place it in the field.

c:\windows\system32\gzkfbc.exe

Then hit Submit
The scan will take a while before the result comes up so please be patient.
Then copy the result and post it here in this thread.

If Jotti's service load is too high, you can use the following scanner instead:

Hi Dan12.

I'm getting a "file not found" error and I cannot locate that file on my PC through a search.

[hoorock]

And this XP machine has a single "admin" user, so don't worry about privileges or user account issues. Thanks for your help.

WITH ALL OTHER WINDOWS CLOSED Click on Fix Checked and exit

Let's see if we can find it this way:

We need to reveal system folders

• Close all programs so that you are at your desktop.
• Double-click on the My Computer icon.
• Select the Tools menu and click Folder Options
• After the new window appears select the View tab.
• Place a checkmark in the checkbox labeled Display the contents of system folders
• Under the Hidden files and folders section select the radio button labeled Show hidden files and folders
• Remove the checkmark from the checkbox labeled Hide file extensions for known file types
• Remove the checkmark from the checkbox labeled Hide protected operating system files
• Press the Apply and then the ok button and shut down my computer
• Now your computer is configured to show all hidden files.
• For you and the tools to be able to see appropriate files we need to Show Hidden Files

Re-boot into safe mode

• Next, please reboot your computer in Safe Mode by doing the following:
  
• Restart your computer
  
• After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
  
• Instead of Windows loading as normal, a menu should appear use arrow up to highlight
  
• Select the first option, to run Windows in Safe Mode hit enter.
  
• For additional help in booting into Safe Mode, see the following site:HERE
  

Right click start, In the drop down menu click "Explore" Then navigate to each file\ folder in the left hand pane, which will reveal its content in the right hand pane, highlight file or folder right click and Delete, if present:
