Avast Antivirus Home Edition on PCLinuxOS 2011.6

Hi all.

Yes yes yes… I know… Linux does not needs antivirus software. True. BUT then – if You are dualbooting with Windows You may want to be able to check the other OS once in a while… Rootkits / malware / spyware / rougeware / viruses and so on and so forth… Even if You are not dualbooting another way of using this would be to use Your remaster to check Your computers at home that are using Windows from the LiveCD / LiveDVD level… Seems useful right? You can access the Windows partitions with read / write permissions under Your PCLinuxOS. Nastiness cannot hide itself from the antivirus with few entries in the registry… Sounds really good… So how does one installs Avast on the PCLinuxOS…

First we need to download a copy of it (it’s legal if You are using it at home on a non-commercial machines. For more info read the Terms and Conditions).

Open konsole and issue this command:

wget -c http://files.avast.com/files/linux/avast4workstation-1.3.0-1.i586.rpm

Now wait for it to finish downloading

give a root’s password when asked.

Now for the installation part issue this command:

and wait for it to finish.

25th January 2012 EDIT:

If You follow this HOWTO and You get

E: Couldn't find package avast4workstation-1.3.0-1.i586.rpm

error then open Dolphin in your /home/login directory. Go to View > Show Hidden Files (make sure it’s ticked),

MiniMe fix

then look for the file, .bashrc, and open it with kwrite. Look for a line;

alias su='su -'

Put a comment in front of that line # so it looks somewhat like this:

# alias su='su -'

Save the file.

Reboot. Redo the howto from step one. It should work without problem for You now.
