You might have better luck in Safe Mode with Networking
(Reboot and when you see the maker's logo, hear a beep or it talks about F8, start tapping the F8 key slowly. Keep tapping until the Safe Mode Menu appears and choose Safe Mode with Networking. Login with your usual login.)
See if you can get OTL to run:
Download OTL from
and Save it to your desktop.
Run OTL (Vista or Win 7 => right click and Run As Administrator)
select the All option in the Extra Registry group then Run Scan.
You should get two logs. Please copy and paste both of them.
:!: It must be saved to your desktop, do not run it from your browser:!:
:!: Disable your Antivirus software when downloading or running Combofix. If it has Script Blocking features, please disable these as well. See: http://www.bleepingc...opic114351.html
Download and Save this file -- to your Desktop -- from either of these two sources:
Win 7 or Vista: Right click on ComboFix and select Run As Administrator to start the program.
XP: Double click on ComboFix
* :!: Important: Have no other programs running. Your Task Bar should be clear of any program entries including your Browser.
* A window may open with a series of Disclaimers. Accept the Disclaimers to start the fix. Allow it to install the Recovery Console then Continue. When the scan completes Notepad will open with with your results log open. Do a File, Exit and answer 'Yes' to save changes.
A caution - Do not run Combofix more than once. Do not touch your mouse/keyboard until the scan has completed, as this may cause the process to stall or your computer to lock. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs, please reboot to restore the desktop. Even when ComboFix appears to be doing nothing, look at your Drive light. If it is flashing, Combofix is still at work.
A file will be created at => C:\Combofix.txt. I'll need to see that in your reply.
If all else fails then try the AVG rescue disk:
