Avast causes slow boot and black screen
« on: August 25, 2017, 11:49:57 AM »
I have installed Avast free then my PC is slowed down so much at boot with a black screen after Welcome screen.
I have run into this problem many times and many years ago (from 2013). Every time I re installed my Windows 7 and then installed Avast, it happened. By investigating the boot procedure (using Windows Performance Tools Kit from Microsoft), I'm sure it's caused by Avast. To make sure this is true, I re-installed my Windows 7 (format the whole HDD), then get updates from Microsoft, installed all necessary softwares. Everything is fine. Just right after I installed Avast, it happens.
Watch the video carefully: https://www.youtube.com/watch?v=TAPfVzApI3g

All settings are default. I just install File system shield, Behavior shield and Web shield.

Feel free to get more information from me.

I use the latest version 17.5.2303 with only 3 shields installed, Windows 7 pro 64 bit SP1
I use MalwareBytes but just free version (Real time protection is disabled by default of this version, it won't start at Windows), no others security sofwares
The HDD is about 80-100% disk usage during the black screen.

How do you know the disk is used that much if the screen is black ?

Same here, but it happened only once. It was first out of 3 reboots.
Maybe it was emergency update or something.

Avast Free 17.5.2303
