Hello let try this

Please click Start > Run, type inetcpl.cpl in the runbox and press enter.
Click the Connections tab and click the LAN settings option.
Verify if "Use a proxy..." is checked, if so, UNcheck it and click OK/OK to exit.


This infection changes settings on your computer so that when you launch an executable, a file ending with .exe, it will instead launch the infection rather than the desired program. To fix this we must first download a Registry file that will fix these changes. From a clean computer, please download the following file and save it to a removable media such as a CD/DVD, external Drive, or USB flash drive.

FixNCR.reg

insert the removable device into the infected computer and open the folder the drive letter associated with it. You should now see the FixNCR.reg file that you had downloaded onto it. Double-click on the FixNCR.reg file to fix the Registry on your infected computer.

OK, lets do 2 things.
Reset IE and run SFC.
See To reset Internet Explorer automatically
How to reset Internet Explorer settings



SFC
Please run SFC (System File Checker)
Please run System File Checker sfc /scannow... For more information on this tool see How To Use Sfc.exe To Repair System Files

NOTE for Vista/WIN 7 users..The command needs to be run from an Elevated Command Prompt.Click Start, type cmd into the Start/Search box,
right-click cmd.exe in the list above and select 'Run as Administrator'


You will need your operating system CD handy.

Open Windows Task Manager....by pressing CTRL+SHIFT+ESC

Then click File.. then New Task(Run)

In the box that opens type sfc /scannow ......There is a space between c and /

Click OK
Let it run and insert the CD when asked

thank you

I feel there is a protected malware,so we need a deeper look. Please go here....Preparation Guide ,do steps 6-9.

Create a DDS log and post it in the new topic explained in step 9 which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If GMER won't run skip it and move on.

Let me know if that went well.
