Linux防病毒，並不代表沒有病毒，只是數量過少。因技術精英發現漏洞後即時打補丁，病毒很少。
有興趣的同學可以嘗試下Ubuntu 11.04 安裝殺毒軟件ESET NOD32 。（這和脫了褲子放屁沒有什麼區別）
There are few viruses that effect Linux based systems. It’s needless to install an antivirus software in Ubuntu for personal use. But if you have Windows installed aside Ubuntu in your machine, or you have a removable disk that aways plugged into other Windows machines. It’s a good choice to do virus scan on Windows partition or removable disk while in Ubuntu.
1.) Download NOD32 Antivirus 4 for Linux Desktop from: http://www.eset.eu/download/registered.
2.) Once download finish, make it executable by check “All executing file as program” on its right-click menu Properties window Permissions tab.
3.) Now, double click to run the installation file. At this step, I got “Please install following files or packages: usr/lib/gconv/UTF-16.so”, and it can be fixed by:
open a terminal window and create directory:
sudo mkdir /usr/lib/gconv
then make a link for UTF-16.so:
sudo ln -s /usr/lib32/gconv/UTF-16.so /usr/lib/gconv/UTF-16.so
4.) follow the on screen prompts and finally reboot.
