avast: can not initialize avast! engine: Invalid argument

I was unable to use my Avast AV on Linux, so I stumbled here due to the similar error message.

The solution as given in the blog;

sysctl -w kernel.shmmax=100000000

It works for me!

Indeed, works well then. Where should you make the change to have it permanent?

Add extra lines to:


# Enable more Kernel memory for Avast Antivirus
kernel.shmmax = 128000000
