AntiVirus/Firewall - Google Toolbar

Asked by brental

Is there a need for any AntiVirus and/or Firewall software like one has in Windows XP? I just installed Ubuntu and like this a lot. Very stable and a lot more organized. Also, I am guessing the Google toolbar doesn't work with Firefox with Ubuntu? I installed it and it seemed to have disappeared. -Thanks-

You don't need any special antivirus software on Linux.
If you need a firewall depends on your needs. Although Linux has with netfilter/iptables a powerful integrated firewall, a common desktop system doesn't really need it.

I don't use Google Toolbar, but according to the system requirements ( it should run fine on Ubuntu. Perhaps it is disabled in the options?

Welcome to Ubuntu, have a lot of fun.

Also, if you can't get Google Toolbar to work, you could try Googlebar (, which works very well and doesn't lack any major features.

So why does Linux not need any AntiVirus or Firewall software? Sorry for being so complicated!

Actually, if it does get infected with a virus then how is it better than XP?

There aren't any ports open by default in the Ubuntu install so that a firewall isn't really needed.

iptables is part of the default ubuntu install, and also shorewall is part of the main ubuntu distribution.

There are several programs you can install to make configuring iptables easier, you may want to try firestarter or gnome-lokkit

There aren't many viruses for linux, and there are none that are causing widespread problems, mainly because they find it difficult due to spread for many reasons.

You can install clamav if you're still concerned about them.
