Windows 10 won't turn on after installing avast
« on: September 25, 2015, 12:32:33 PM »
I just did a clean install of Windows 10 on my cousin's laptop but after installing Avast, Avast service won't run. I tried to reboot but it says it failed to boot. Same thing when I tried to restart again. It worked when I tried to do a system restore to before Avast was installed.

The almost same thing happened to me. I installed AVAST and it did a scan of the computer and wanted to do it during the startup of the system and after that is says that my drive is locked and i cannot start windows 10! And since its locked i cant install through dvd either... But on another hdd it went successfully but i want my old install back. What to do AVAST?

Guys I found a solution and worked for me ;D

Here it is....
Install Avast Antivirus but don't restart the system
Now right clicking the avast icon on the task bar -> avast shields control -> disable until computer is restarted
Now right click on the task bar ->select task manager -> select more details (if it is only in simple view) -> select startup tab
right click on Avast! Antivisrus -> disable it
Now restart your computer
Now manually run Avast
Now again select task manager -> select more details (if it is only in simple view) -> select startup tab
right click on Avast! Antivisrus -> enable it.

So... now its done.
Check it now

Have fun  ;)

If you're running Windows 10, you need to use the latest version.
If you've just installed the latest version and one of the shields didn't start, just reboot the system again.
