Download the .DEB from

Install it using GDebi or use the terminal.

sudo dpkg -i file_name.deb

If you don't get any icon/menu entry in the Application-Accessories menu.
Then run this in the terminal

cd /usr/lib/avast4workstation/share/avast/desktop
sudo ./install-desktop-entries.sh install

If you like to use GTK 2.x then work your way to the avast directory.

cd /usr/lib/avast4workstation
Then just remove the

sudo rm -rf lib-x11/

sudo rm -rf lib-gtk2/
Thats it.

EDIT: Screenshot GTK 1.2
EDIT 2: Added screenshot using GTK 2. See attachment (last img.) And added som info on how to make it use GTK 2.x, Thanks from forum members in this thread.

Why would you need a virus scanner? All software is from a trusted source (apt) and ubuntu doesn't led you run sofware as root without password.

If you want to send a file you downloaded from the web to a Windows user, it's a good idea to make sure it's virus-free.

I managed to install the 32 bit version of avast on 64 bit Kubuntu with the following command and it works fine. You do need the 32bit libs though.

sudo dpkg -i --force-architecture avast4workstation_1.0.6-2_i386.deb

I had already installed the 32bit libs (i think when i was installing wine)

not 100% :confused: sure but if i remember correctly it was from the following post

the code i think you need you need is (copied from the other post):

Download the 32 bit libs
http://packages.ubuntu.com/cgi-bin/download.pl?arch=i386&file=pool%2Fmain%2Flibx%2Flibxxf86dga%2Flibxxf86dg a1_1.0.0-0ubuntu3_i386.deb&md5sum=f1f2a20a6db2bf5eb44db45cdb3a1337&arch=i386&type=main (http://http://packages.ubuntu.com/cgi-bin/download.pl?arch=i386&file=pool%2Fmain%2Flibx%2Flibxxf86dga%2Flibxxf86dg a1_1.0.0-0ubuntu3_i386.deb&md5sum=f1f2a20a6db2bf5eb44db45cdb3a1337&arch=i386&type=main)
Save the files to your desktop.

First we will install the needed libraries.

cd ~/Desktop dpkg -x libxxf86dga1_1.0.0-0ubuntu3_i386.deb libs sudo cp ~/Desktop/libs/usr/lib/* /usr/lib32

You now ahve the needed 32 bit libs and can force avast to install using them

sudo dpkg -i --force-architecture avast4workstation_1.0.6-2_i386.deb

Hope this helps, It worked for Me. 8)

Now a question,
Does anyone know if there is an on access scanner for avast on linux?

October 13th, 2006, 04:33 PM
Thankee for the heads up. Didn't even know Avast! had a deb build.

October 26th, 2006, 02:23 PM
All ok. I downloaded the file but:
paogeorge13@paogeorge-desktop:~$ sudo dpkg -i avast4workstation_1.0.6-2_i386.deb
dpkg: error processing avast4workstation_1.0.6-2_i386.deb (--install):
cannot access archive: No such file or directory
Errors were encountered while processing:

I tried the second option but nothing again! Could you help me?
Thanks in advance! :)

October 26th, 2006, 02:48 PM
ok. I solved the problem. Cya my friends!

October 27th, 2006, 01:29 PM

Thank you, thank you, thank you. Everything worked like a charm. :-D

October 27th, 2006, 06:02 PM
I wasn't aware they had a .deb file, thanks :D Will come in handy at work, where I get to scan for viruses a lot xD

if you look in /usrlib/avast4workstation
you find /etc /lib-gtk2.0 and lib-x11

if you copy your own libraries to here, and recreate the symlinks
to the new libraries you get avast with a gtk2.0 interface matching
you're ubuntu theme...

October 28th, 2006, 05:37 PM
I think if you like to use gtk 2.0, you can delete the folders from the avast dir.

awesome thank you very helpful

November 3rd, 2006, 09:46 AM
sudo rm -rf lib-x11/
and sudo rm -rf lib-gtk2/
helped, avast is now ubuntu looking

November 3rd, 2006, 10:35 PM
added som info..

November 4th, 2006, 09:47 PM
Thanks for this info. I needed a simple antivirus to check e-mail I was sending to Windows users.

November 19th, 2006, 08:41 PM
If I would like to add avast to /etc/cron.weekly so that it is updated and run every week, what script do I need?

Thank you.

November 19th, 2006, 09:11 PM
If you run * avast --help * in the terminal you will get all options you can use from the command line. also * avast-update * will update it from the cmd.

But I guess it will run as root if you use the cron.

Thank you all for the nice instructions.
But, I have a problem.
I am behind my college proxy server. But I did not find a way to specify these proxy settings in Avast GUI. So when trying to update definitions, I get connect() timeout error.
Any idea how to resolve this?

@ Urvang

I don't know the answer to your question but I see no one has responded yet. I hope you resolved your issue, and if not I suggest checking out the Avast forums to see if someone there may have an answer for you. Avast isn't a directly supported software by Ubuntu development. That said, there are many people here that can help, so keep an eye on this thread and some one may see your post and have an answer if you haven't already found one.

http://forum.avast.com/index.php?board=5.0 = This is the Linux/Unix board for Avast 4.

If you have resolved your issue, please post for all to see. I'm sure others will need this info in the future. ;)
