Re: Avast causes slow boot and black screen

after a few days, It seems that it still happens, about 50% of the boot times.
I have run into this problem for 3 years. Two years ago, I installed another Win 7 on the same HDD to investigate more deeply. The second Win 7 has Avast installed and actually, it rarely has a black screen and the boot isnt really slow.
Here is the race between the two Win 7 on my laptop

I don't know if my files or any specific can affect. On my main Win 7, I store documents on Documents folder of Windows, Music and Videos on C:\Media folder, some programs are installed on C, some on other partition. Will Avast emergency update cause? if it's true, why black screen doesn't happen on the second Win 7?

Try: Avast GUI -> Settings -> Troubleshooting -> Load Avast services only after loading other system services

Loading Avast after other services doesn't help, at least at firts 3 boots after I change the settings.
Can I get your personal support, teamviewer or mail or something?

I have installed the new version, but it seems slower than the beta.
The black screen still happens about 50% of boots.
I have checked that exclusion contains all thing you say, load avast service after system services.
I also set the for program update "Ask when an update is available"
Do you have any suggestion?

Remove Wondershare as it is at least a PUP.

It isn't causing the problem. :)
