I am a newbie to Ubuntu 11.10, am running an HP desktop using XP. I got hacked and had to format C. While I re-installed XP, I then installed Ubuntu 11.10 (called running side-by-side?) and currently, Yikes!, have no virus protection. I searched the Ubuntu site, found Avast, did a download, have an email whose instructions seems to be for XP. I cannot find a way to run the download free Avast for my personal use. Help.
In the downloaded folder I think this file is what I need to "run."
avast4workstation-1.3.0-1.i586.rpm
When I right click for properties, I cannot find a program to open or run this... Help!
