Windows 8 and Avast black screen problem |SOLVED

Avast Black Screen Problem – windows 8 | solved

You might have encountered a black screen problem after installing Avast antivirus on your Windows 8 operating system. You would notice that once your account loads the screen automatically turns black and you won’t be able to see anything except a moveable cursor.

I recently encountered this problem and I didn’t have any clue as well. I tried to start a new process (explorer.exe) using task manager but looked like it was blocked as it was not appearing under the process tab.  I guessed that it could be Avast,  I’m not blaming avast personally but all antiviruses act weirdly sometimes (My past experience) . The only reason I’m using avast is because its free and also I could get a paid version for free. Want to know more? Read:  How to get Avast Internet Security 3Yr License For Free

    Hello,
    I have same problem with windows 8 and Avast, but when I try to open Task Manager, it shows up for a split second and then disappear again.

    • http://www.bleepingtech.com Trilma Rose

      Try to login using safe mode (F8)

  • Niels

    Thanks for quick reply
    Have read that you can not use F8 in Windows 8 for Safe Mode, but instead Shift+F8
    Have tried that several times but does not work.
    This Windows 8 is running in VMware Workstation so perhaps that is the problem

    • http://www.bleepingtech.com Trilma Rose

      Did you try Ctrl+Shift+Esc to open task manager
      I’m not sure of the VMWare,I never used it before to be honest but here is video tutorial that explains booting into windows safe modem from your VMware Virtual Machine.. http://youtu.be/clY0n6PO5Kg . If this doesn’t work,try to restore the computer using system restore options.

  • Niels

    Problem solved:
    In VMware you use Ctrl+Shift+Ins for task manager, but the task manager disappeared again.
    From a Microsoft site I found the way to log in Safe Mode.
    If you’re not signed in to Windows, tap or click the Power icon from the sign-in screen, hold Shift, and then tap or click Restart

    Hey :'( You helped me alot !.. i didn’t notice that avast is the problem why i encountered the black screen issue. i reformat my pc for several times because i thought it’s a virus. and now.. its okay because of you! .. THANK You!!! :)

    I have had this black screen problem 3 times now, all occurred after my very first reboot after activating my copy of Avast. The first time I thought I screwed something up, this is the first PC I built, it’s over 5 years old, and prone to issues. So I did a system refresh through the W8 boot disc (no restore points, I turn them off), lost a lot of stuff, but not that big of a deal. The second time, I messed around with safe mode and uninstalled Avast, that worked. The third time (right now) I learned about the behavioral shield on the Avast forums, and after uninstalling in safe mode, reinstalled without the Behavioral Shield. Seems to be working, I didn’t get the answer from here first, but I can attest that this is a working solution to the black screen after logon problem. So thank you.

    Also, if you have task manager issues, like I did (pops up for 2 seconds without the actual menu loaded, and then disappears), restart, and at the password screen click the power off button, and hold shift and hit restart. It will give you a menu, and you can access “Advanced Startup Options”, that is where you can find safe mode.

    Thanks again, this is good advice.

      Try to work in safe mode. Try to hit Ctrl+Shift+Esc a couple of times or Ctrl + Alt + Del in safe mode.
