Hello kreak17 and welcome to the TomCoyote Forums

My name is Trevuren and I will be helping you with your problem.


Your computer appears to have been infected by a backdoor trojan. These programs have the ability to steal passwords and other information from your system. If you use your computer for sensitive purposes such as internet banking then I recommend you take the following steps immediately:

* Use another, uninfected computer to change all your internet passwords, especially ones with financial implications such as banks, paypal, ebay, etc. You should also change the passwords for any other site you use.
* Call your bank(s), credit card company or any other institution which may be affected and advise them that your login/password or credit card information may have been stolen and ask what steps to take with regard to your account.
* Consider what other private information could possibly have been taken from your computer and take appropriate steps

This infection can almost certainly be cleaned, but as the malware could be configured to run any program a remote attacker requires, it will be impossible to be 100% sure that the machine is clean, if this is unacceptable to you then you should consider reformatting the system partition and reinstalling Windows as this is the only 100% sure answer.

If you wish to reformat then please let me know in your next response, I'll now continue with instructions for cleaning.


Download SDFix and save it to your Desktop.

Double click SDFix.exe and it will extract the files to %systemdrive%
(Drive that contains the Windows Directory, typically C:\SDFix)

Please then 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, tap the F8 key continually;
  • Instead of Windows loading as normal, the Advanced Options Menu should appear;
  • Select the first option, to run Windows in Safe Mode, then press Enter.
  • Choose your usual account.
  • Open the extracted SDFix folder and double click RunThis.bat to start the script.
  • Type Y to begin the cleanup process.
  • It will remove any Trojan Services and Registry Entries that it finds then prompt you to press any key to Reboot.
  • Press any Key and it will restart the PC.
  • When the PC restarts the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
  • Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt
    (Report.txt will also be copied to Clipboard ready for posting back on the forum).
  • Finally paste the contents of the Report.txt back on the forum with a new HijackThis log

Regards,

Trevuren

Well that backdoor was removed by another process prior to your posting your log. That is good. Now for a more in-depth look at your system:

Please download this file - combofix.exe by sUBs
  • You must download it to your Desktop
  • Double click combofix.exe & follow the prompts.
  • When finished, it will produce a log. Please save that log to post in your next reply along with a fresh HJT log.
Note:
Do not mouse-click combofix's window while it is running. That may cause it to stall.

Regards,

Trevuren
