    I think my win 8 has a virus.


    I think my win 8 has a virus.
    When you start up it will get passed the win 8 bootup screen into where it will log you in (i have set it so it will auto log me on), this process takes 2-3 mins. It will show the desktop for 30 secs then shows a blank green screen where it shows the mouse loading image. Its been around 20mins and still the same.

    I have done a system restore, it completed sucessfully but it obviously hasnt removed the virus

    What can i do

    Problem is that i cant access windows to change any settings.

    Will i be able to install win 8 over my current copy without deleting any files. I can the access the current file system through the new install & delete the virus

    During an "upgrade" installation, windows keeps a copy of the old OS so your files should be safe. Microsoft confirms it, check here : Update to Windows 8.1: FAQ - Microsoft Windows Help (and click will I be able to keep my files...) and here Windows 8 and Windows 8.1 Upgrade Paths

    Another solution is to dowload and install a live cd : List of live CDs I generally use Knoppix, this is linux based. If you're more comfortable with windows you can try Ultimate Boot CD for Windows . You'll be able to boot from it and copy/move any files you want to save to a safe location.

    But your problem might not be related to a virus, it could be related to a driver missing, a recently installed application which is incompatible, or maybe a botched update. Try starting in safe mode to see if it helps : How To Start Windows 8 or 8.1 in Safe Mode

    Are your specs current in your profile ? (Win 8 RTM, 1GB Ram, Atom processor)

    Please confirm your specs to include your AV scan results, and apps/additional software.

    Does your Antivirus detect virus ? Scan with malwarebytes.org as a 3rd party AV.

    Also, have you tried to disable the auto logon and go with a normal log on ?

    Have you tried the Shift+F8 to boot into safe mode??

    Most viruses nowadays embed themselves in the 1st restore point. You could try rolling back to the 2nd or 3rd restore point before the problems started.

    D/L & run the following scanners & post the results.

    Malwarebytes (The Free Version)

    Malwarebytes : Malwarebytes Anti-Malware removes malware including viruses, spyware, worms and trojans, plus it protects your computer

    TDSSKiller (To rule out the possibility of a rootkit)
