Any time I use Alt+F2 to open command line and I type a command such as:

sudo apt-get install clamav clamtk

I click on it and it doesn't do anything. Am I not supposed to click on the icon that comes up and reboot or am I missing a step?

Any help will do,

use gksudo instead of sudo, i.e.,

 gksudo apt-get install clamav clamtk

I prefer to use terminal for this. You can start it by pressing Ctrl-Alt-t

PS. In 11.10 you'd probably need to check if the shortcut is assigned, but for 11.10 it's not the biggest issue.
