    Reboot in safe mode and rescan.

    Your antivirus cannot remove a live process and when you go into safe mode the virus does not get loaded into memory.

    Try formatting your PC…

    These steps are for formatting your primary drive (normally C:) in Windows 2000, XP, Vista, and Windows 7 and to reinstall the operating system.

    The easiest way to format your computer is by locating your operating system CD. Look for a CD or DVD that specifically says “Operating System” or “System Restore”. Insert the installation disc into your CD or DVD drive.

    Restart your computer.

    When your computer is restarting, you will be prompted to “Press any key to boot from CD”. Simply press any button on your keyboard when you see this message. If you do not see this message when you restart your computer, you may need to reset your boot disk sequence. *

    *To reset the boot sequence, go into BIOS mode. To do this, restart your computer and while restarting press the F1, F2, F10, or maybe the delete key (your computer screen will say “To enter setup press xxx”. You only have a few seconds to press the correct key, so if you miss it you will need to restart your computer and try again. Once you have successfully entered the BIOS mode, look for your boot sequence options. Set the CD ROM drive to be the 1st in the boot sequence. Save your changes and exit.

    The CD will load a blue screen, then after a few minutes will ask you to press Enter to set up Windows.

    You will then be prompted to select where to install Windows. There will be a box on the lower half of your screen that will either show “Unpartitioned space xxxMB” or will have “Partitioned space xxxMB”. Highlight which partition you wish to format (typically it will be the unpartitioned space or the space with the largest partition by most megabytes). Hit Enter after selecting the space to partition.

    The next step is to choose which file system to format the drive with. The NTFS option will be the fastest option. For most formatting purposes, choose the option that ends in “Quick”. Press Enter when done.

    The computer will then begin the formatting process. This process may take a while depending on the size of the hard drive you are formatting and the speed of hard drive.

    As soon as the drive has been formatted, the operating system files will be copied to the hard drive and the operating system will start installing.

    Try this:

    Firstly, boot your computer to the Safe Mode menu screen. You do this by repeatedly pressing F8 as soon as you boot up. Once there, use the arrow keys to highlight Safe Mode with Networking. Continue to boot from there, by pressing Enter.

    If that’s successful, download and run TDSSKiller.exe from Kaspersky Lab. It’s tiny, and takes just a minute to run. It hunts down and kills a specific family of rootkits:

    Regardless of the results, download the free version of Malwarebytes’ Anti-Malware (MBAM). Install it, get updates and run a full scan (still in Safe Mode). This is a direct download link. Copy and paste it into your browser’s address bar, and press Enter.

    http://www.myantispyware.com/mbam

    After that, boot normally and run another full scan with MBAM. It will detect any malware that wasn’t running in Safe Mode.

    If the problem still exists, download and run the free Kaspersky Virus Removal Tool:

    http://support.kaspersky.com/viruses/utility

    You should now delete TDSSKiller.exe and the Kaspersky Virus Removal Tool, as updated versions are often made available. Malwarebytes’ Anti-Malware can be easily uninstalled, should you wish to do so, but it may prove to be beneficial in the future.

    Hope this helps.

    Boot in safe mode with networking by repeatedly tapping on the F8 key the moment you turn your computer on.

    If you cannot connect to any site on the internet, reset your connection settings by clicking on Start > Control Panel > Network and Internet > Internet options > Advanced > Reset.

    Download and run these in exact order:
    http://www.bleepingcomputer.com/download/anti-virus/rkill
    http://download.bleepingcomputer.com/reg/FixNCR.reg
    http://support.kaspersky.com/downloads/utils/tdsskiller.exe
    http://www.malwarebytes.org/products/malwarebytes_free

    If you still can’t download from the infected computer, use a different computer and transfer the listed files to a flash drive or CD.

    When you run a copy of RKill in Safe Mode (it has several renamed versions but any one should do), wait for it to give you a report on what processes were temporarily terminated to allow your scanner to run. Follow it up by running the FixNCR.reg just to make sure that the registry entries for your browser were not tampered as the registry may have been modified to reload a malware each time you open your browser. Run the TDSSKiller to fix your Google Redirect problem in case you have that too.

    Next, install MBAM, update it and do a full scan. Delete whatever it finds. After that, boot in normal mode and see if you still have a problem.

    If your programs, shortcuts or files seem to be missing, go to this site and follow the instructions:
    http://www.bleepingcomputer.com/forums/topic405109.html

    If you’re having difficulty connecting to some sites, check and make sure your HOSTS file looks like this:
    http://support.microsoft.com/kb/972034

    You may have to reset it and restart the computer if it doesn’t match with the default.

    Finally, if you don’t have a decent antivirus get this free one and do a full scan:
    http://www.avast.com/free-antivirus-download

    Oh, consider using the 14-day trial version of MBAM Pro. It blocks threats in real-time. After it expires, it will automatically downgrade to the free version which is only an on-demand scanner/remover of malware.
