Sometimes I have to use Avast antivirus for Linux but there is always some problems:

  • Avast for Linux is a 32bit application (so you must force the installation on 64bit systems)
  • On many systems you cannot run Avast, because this error message: “An error occurred in avast! engine: Invalid argument”

Here a quick fix:

  • first, force the installation with this command: sudo dpkg –force-architecture -i avast4workstation_1.3.0-2_i386.deb
  • then edit this file /usr/lib/avast4workstation/bin/ adding after export PATH this line “sudo sysctl -w kernel.shmmax=128000000”
