Hi Thunder7delta,

Welcome to Tech Support Forum!

OK, let’s do this next.


Please run HijackThis and click "Scan". Place a check (tick) next to the following entries (if present):

O4 - HKLM\..\Run: [KernelFaultCheck] %systemroot%\system32\dumprep 0 -k
O4 - HKCU\..\Run: [mschkdsk.exe] C:\WINDOWS\system32\mschkdsk.exe
O4 - Startup: PowerReg Scheduler.exe
O9 - Extra button: (no name) - {CD67F990-D8E9-11d2-98FE-00C0F0318AFE} - (no file)
O23 - Service: FreezeScreenSaver - Unknown owner - C:\WINDOWS\system32\FreezeScreenSaver.exe



Close ALL programs and browsers (including this one), leaving ONLY HijackThis open, then click "Fix checked".

Then please exit HijackThis.


NEXT:

Using Windows Explorer, please navigate to and delete the following FILES (if they exist):

C:\WINDOWS\system32\mschkdsk.exe
C:\WINDOWS\system32\FreezeScreenSaver.exe


Please let me know if you encountered any problems finding or deleting the files.


NEXT:

Please go to Start -> Run and type (or copy and paste) the following lines in the Open field, ONE AT A TIME, then click OK:

sc stop FreezeScreenSaver

sc delete FreezeScreenSaver



NEXT:

Please download CCleaner (freeware) and save it to your desktop:
  • Run the CCleaner installer.
  • During installation process, please UNCHECK "Add CCleaner Yahoo! Toolbar".
  • Once installed, run CCleaner and click the Windows tab.
  • Select the following:
    • Check everything under the Internet Explorer section.
    • Check everything under the Windows Explorer section.
    • Check everything under the System section.
    • Check ONLY Old Prefetch data under the Advanced section.
  • Then, click the Applications tab:
    • UNCHECK everything there.
  • Next, click the Options button, then click the Advanced button:
    • UNCHECK : "Only delete files in Windows Temp folders older than 48 hours".
  • Next, click the Cleaner button, then click the Run Cleaner button (bottom right), then Exit.

CAUTION : Please do NOT use the Issues button. This is a built-in registry cleaner. If you don’t know how to use it, you may cause irreparable damage to your system.


NEXT:

Let's run an online scan to make sure we're not leaving anything behind.

Please do an online scan with Kaspersky Online Scanner:
  • Click on Kaspersky Online Scanner.
  • You will be prompted to install an ActiveX component from Kaspersky, click Yes.
  • The program will launch and then begin downloading the latest definition files.
  • Once the files have been downloaded click on Next.
  • Now click on Scan Settings.
  • In the scan settings make sure that the following are selected:
    • Scan using the following Anti-Virus database:
      Extended
    • Scan Options:
      Scan Archives
      Scan Mail Bases
  • Click OK.
  • Now under select a target to scan:
    • Select My Computer.
  • This program will start and scan your system.
  • The scan will take a while so be patient and let it run.
  • Once the scan is complete it will display if your system has been infected.
    • Now click on the Save Report As button.
    • In the File name: field, type kavscan.
    • In the Save as type: field, select Text file (*.txt).
  • Save the file to your desktop.
  • Copy and paste that information in your next post.


NEXT:

Please reboot your computer normally into Windows, and then please post the log from the Kaspersky scan and a new HijackThis log.

How are things running now?
