Will Avast work for Ubuntu? I would love to use avast on my Ubuntu os. I went to the Avast site and it gave me 3 different file download choices for Linux. one was a rpm,deb and the other just took me to a page with a bunch of letters and signs? How do i install new programs using ubtuntu and if avast will not work, what is the best free linux antivirus?

Step 1. click here to Download avast
step 2 : enter the following command /Downloads
cd ./Downloads
sudo dpkg -i avast-linux-home-edition-1.3.0.deb
step 3 : To start using avast antivirus software, You need to Register with avast here to get a free license key (Don’t worry it’s free!). The license key will be delivered to your email address within 24 hours (usually within a couple of hours).
step 4 : Start the program and enter the license key.
step 5 : To achieve database updating (in my Ubuntu 12.04), the treatment according to Error message in Avast! with the value
256000000according to the comment by 'pbhj' is necessary. That’s all!

You use .deb packages for ubuntu.
After you download them, you just double-click on the .deb and you should be fine.
A better option would be to use the terminal as it's more verbose
dpkg -i <.deb file>
IMHO, in the current time, Linux does not require an anti-virus per-se. Internet security, sure.

FYI...I kept getting an error when trying to start Avast after installation. The message was: an error occurred in Avast engine; Invalid argument. Found this post from Pure Blooded on another site and this code put into the terminal solved the error and now the program will run. You might encounter similar problem.

Re: An error occured in avast! engine: Invalid argument
Run this command
sudo sysctl -w kernel.shmmax=128000000
kernel.shmmax = 128000000
