Try this, if you are at the point of reformatting Windows then you've got nothing to lose! What you've got here is what is known as a "sleeper" Trojan, quite sneaky.
Option 1.
Download HJTInstall.exe
Save HJTInstall.exe to your desktop.
Doubleclick on the HJTInstall.exe icon on your desktop.
By default it will install to C:\Program Files\Trend Micro\HijackThis .
Click on Install.
It will create a HijackThis icon on the desktop.
Once installed, it will launch Hijackthis.
Click on the Do a system scan and save a logfile button. It will scan and the log should open in notepad.
Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
DO NOT use the AnalyseThis button, its findings are dangerous if misinterpreted.
DO NOT have Hijackthis fix anything yet. Most of what it finds will be harmless or even required.
Option 2
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
Another way is to go into REGEDIT.EXE from Command prompt, but you could accidentally delete the wrong stuff there.
My last suggestion would be to use a rootkit device-
technet.microsoft.com/en-us/sysinternals/bb897445.aspxYou can download Rootkitrevealer for free here and literally root out a problem.
What is strange is that the formatting hasn't got rid of the virus. When you reload everything and get it all set up, make sure you don't log onto internet until your firewalls etc have been set up properly, otherwise the viruses just flood back in.
