Cannot access computer desktop?

So my brother tried downloading something and it brought him to a different page and all the sudden something else came up. Its a fully white screen, it says "enter code" and has digits 0-9 as buttons and a green "submit" button. You cannot get away from the page. Ctrl+alt+del doesn't work, though i can cycle through open programs it won't let me select them. This is still happening even after multiple restarts. After awhile the page goes to "500 internal server error nginx 0.8.55" and I cannot select out of it at all.


Well I figured out it only happens when the internet is plugged it. Tried restoring the computer to an earlier time and it said it might not have worked because of his anti-virus. Tried again with it disabled and it gave the same message. also the screen still comes up. Is it maybe an issue beyond his computer? We are both on the same network and I have no issues.

Update 2:

Well I just had to uninstall his antivirus and restore it and it is working fine now. Thank you all SO much for the replies :)

    It would help to know what he was trying to download and where from.  This is clearly some sort of malware.  Try this:

    Download, install, update and do a full scan with either SUPERAntiSpyware (SAS) or MalwareBytes Anti-Malware (MBAM) (or both, even -- but one at a time), and let them remove whatever they find.  Make sure you turn off System Restore before you do this.  You'll most likely need use Safe Mode, and you may need to download them on another computer if your internet access is compromised.  You may also need to run rkill to kill the malware process, and maybe rename the SAS and Malwarebytes executables' file names as well.

    SAS download:

    MBAM download:

    Rkill download:


    There are excellent tutorials on this at Bleeping Computers:

    Rkill tutorial:


    Once it's cleaned up, install a good hosts file to help block unwanted popups, parasites, adware and spyware.  You can read about, download and install an excellent one from   This hosts file blocks hundreds of known malicious URLs.  I've been using one from this website for several years now and rarely get popups and annoying ads.  Revisit the page every couple of months as it is updated from time to time with new sites.


    Also, never use an administrator account for day-to-day use.  Always use a Standard or Limited account.  This will limit the amount of damage these things can do, and prevent them from installing by themselves.

    Restore your computer to an earlier time (before the download). Use SYSTEM RESTORE. Go to and look it up for your version of Windows. It's pretty easy.

    Lol a simple attack virus. Use a harddrive enclosure. It's probably in your home directory. Go in and delete it. And tell your bro to stop downloading p**n lol

    reboot your PC in safe mode by restarting it and spamming the F8 key before it loads windows. then you you can launch whatever you need to clean up this spyware thing.
