Avast Business Antivirus - blank window pops up

[Manley]

Anyone else upgraded to new client version and now upon a reboot, a blank window pops up? The window title just shows “Avast Business Antivirus” but the content is empty. Users now have to click the X button to make it go away. I have Silent Mode turned on.

Hi!

Did this happen only once after the update or does it happen every reboot?

Can you please send me zipped “log” folder from “C:\ProgramData\AVAST Software\Avast”?

Thank you

Petr

It happens after every reboot. When I try to zip the whole folder or select all the files, there is a permissions error.

Disable Avast self defense and try again.

You mean this (See pic)? Isn’t that important to keep turned on?

@misak - has anyone else reported this?

Yep. After collecting the data for Petr, enable it again.
