When finshed following directions, post a
complete HijackThis log.
Important: Create a folder on the C: drive called C:\
HJT.
You can do this by going to My Computer (Windows key+e) then double click on C: then right click and select New then Folder and name it
HJT.
Move HijackThis.exe into this folder as you do not want the HijackThis backup logs in the Temp folder that should be cleaned out periodically.
When you run HijackThis from C:\
HJT folder by double clicking on it and have it "Fixed checked" it will create a backup file of modifications to use if restore is necessary.
Make sure 'show all files' is enabled:

Boot into Safe Mode by tapping F8 key repeatedly at bootup.
More detailed instructions here:

Find and delete if still present:
D:\WINDOWS\Downloaded Program Files\Gbieh.dll <== file
Start HijackThis and tick the boxes next to all these, then close all browser and explorer windows, and tell HijackThis to "Fix checked" if still present.

Reboot and Install the prevention protection below and help your friends from being infected on the Internet.
"An ounce of prevention is worth a pound of cure."
Empty the Recycle Bin frequently.
Run CleanUp! as the Temp folders should be cleaned out periodically as installation programs and hijack programs leave a lot of junk there.

Then reboot to let it clean out what it found.
By the way, in order to improve Internet Explorer (IE) performance the Temporary(TIF)should be cleaned out periodically.
Also, it is a good idea to limit the size of the TIF to 200MB for performance sake.
In IE go to Tools then Internet Options then Settings and move the slider down to 200MB.
Download and install WinPatrol.

Browser settings for increased security:

Install IE-SPYAD then run the install.bat in the ie-spyad folder and SpywareBlaster then keep them up to date as today's Internet is full of nasty infections.

Some of it may not be relevant BUT it will be worth you posting a
