With Avast free installed - Windows 10 lockscreen wont let me enter my password.

Hi there!

Specs:

Asus Laptop Gamers Of Republic (GOR) G75VX

Intel Core i7 3630QM HT 6MB L3 3rd Generation (Ivy Bridge)
8 GB DDR3 (800 Mhz real clock)
Nvidia Geforce GTX 670MX 3GB GDDR5
1 TB Drive

My current version (build) of Windows 10:

Windows 10 Core Edition (Home) fast release build: th2_release Core 10547 (This is a legit copy and is activated)

I’m on the Windows 10 Insider Program and get new builds from the fast release updates. And as such, these builds are by no means considered stable versions, as you may know. The initial release to the public of Windows 10 build 10240 is considered more stable. But, I want to get the new features and such with new builds through the fast release. I know this is most likely the problem with Avast, by me using a newer Windows 10 build. Through time (the builds), I went from build 10240 to 10532 to the latest I have 10547. Avast worked fine until build 10547.

Here is what happens: When I boot my computer up normally, I get to the lockscreen, hit the spacebar to move it out of the way so that I get the screen where I enter my pin or password, but they are frozen. I can’t get a blinking cursor in the password box. I can’t even click on the power button to the right of the screen with the mouse. If I hit the spacebar again, the lockscreen picture comes back. If I hit spacebar once again, the lockscreen picture clears out of the way. But still yet, I can’t enter the pin or password because it all is frozen. At that point, I press the physical power button on the laptop and the machine does shut down. At that point, I use advanced startup and startup in safe mode which allows me at that point to enter my pin or password and then I have to uninstall Avast in order to boot normally. Avast was working fine until I updated to build 10547. I’ve uninstalled Avast in Windows 10 safe mode. Then I can boot into Windows 10 normally and re-install Avast. But, after I reboot, it freezes at the lockscreen again.

Do you have any idea what might be wrong?

Thank you for any help!

  1. Are you running the latest version of Avast: https://forum.avast.com/index.php?topic=176600.0
  2. Are you using CryptoPrevent ???

Hi Bob, thanks for the reply:

  1. Yes, I installed the latest version of Avast twice.
  2. No, I’m not using CryptoPrevent.

I asked because for me it wasn’t Avast that was the problem but CryptoPrevent.
I’m passing this on to the Moderators. Let’s see if we can get a reply from Avast.

Cool, thanks for the help Bob! =)
