I have a Gateway Laptop running Vista. In the last couple weeks I have received noticeable issues mainly related to my browser (both with Firefox and Internet Explorer). I get numerous pop ups and often pages won't load properly. My friend used he's flash Drive on my computer and the next day in lab class the college computer scanned the drive as having the W32 Trojan. This leads me to believe that the same Trojan is on my system (and came form my system).

I went to Process Library.com and typed every process in.
These came back as virus/malware processes:
* csrss.exe
* isass.exe
These came back as possible malware or windows process:
* taskmgr.exe
* winlogon.exe
* traybar.exe
These came back as unknown or undetermined processes:
* sttray.exe
* CEC_MAIN.exe
* zokemita.exe

The zokemita came back as a completely unknown process and when I did a google search only 3 results came back. Two of which had links to a forum on this site and referenced connection to the Vundo Trojan.

I did download Symantec Security Response - W32.Blaster.Worm Removal Tool and had it do a full scan of my system. It wouldn't run in a normal boot, but it was able to do a full scan in safe mode. Unfortunately (or fortunately) it came back a not having found and sign of W32.

From here I don't know what to do. I have listed the system information of a dxdiag run I just did. If you want the full scan let me know, I'll post it.

That's for your time and help!

The processes you listed are legitimate as long as they are in the correct file path
Do not delete any of them


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.

  • 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.
-- 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
