first time ubuntu

Avast.com currently offers a free Avast download for Ubuntu. Unfortunately they only provide a deb package for 32-bit systems. Avast actually runs quite well on a 64-bit system, but the installation requires a few extra steps. This guide will walk you through the process of installing Avast on a 64-bit system.

1. First off, install the ia32-libs package if it's not already installed.
   
   Code:

   sudo apt-get install ia32-libs

   The ia32-libs package must be >= 2.2ubuntu18.
   
   
2. Download the Avast debian package here and save it to your desktop. The instructions below assume that the avast package can be found on your desktop so it's important that you choose your desktop as the download location.
3. After it's downloaded change to your desktop folder.
   
   Code:

   cd /home/YourUserName/Desktop

4. You need to make sure that all of the required libraries can be found in your /usr/lib32 folder. To help simplify this task I've created a libs package for avast and attached it to this post. Simply download the attachment and then type the following:
   
   Code:

   sudo dpkg --force-architecture -i ia32-avast-libs.deb

5. After the Avast package is installed make sure that all of the required libraries are installed. Type the following:
   
   Code:

   ldd /usr/lib/avast4workstation/bin/avastgui
   ldd /usr/lib/avast4workstation/bin/avast

6. Scroll through both lists and make sure that none of them say 'Not found'. As long as you didn't find any libraries listed as 'not found' then you should now be able to run Avast from your Applications menu.
7. and then put the serial key as shown in the 32bit post
