Yes you have a Vundo infection...


Please download SDFix from here 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).
Post that log in your next reply.
=================================
Ok.We need to download ComboFix.exe.
Please visit this webpage for download links, and instructions for running the tool

When the tool is finished, it will produce a report for you. Please post the "C:\ComboFix.txt" along with a new HijackThis log so that we can continue to do any further cleaning that your system may require.

Hi Pancake I've been reading your post for a while now you do a great job. How could you tell this PC had the infection?? I'm trying to learn this stuff

Its a typicalVundo infection.Most of the file names dont make sence and the spelling is meaningless..

You get to know the bad files from the good ones and that can take years. If you are interested http://www.castlecops.com/f67- Trend_Micro_HijackThis_Logs.html and Tech Support Forum run schools if you are interested.

I see. Thanks for the links This one seems not to be working http://www.castlecops.com/f67- Trend_Micro_HijackThis_Logs.html
