Can you tell me if I should install an antivirus or Zone Alarms within Virtualbox If I want to surf the Internet.
Is it enough to have the protection into theI host?
Thanks to all

You need to look at these as a separate computers. So yes you should have protection.
I prefer to use FreeAVG anti-virus software in the guest, and then exclude the folder from being scanned that holds the VDI files from the host. No need to scan them twice.

Thank you for your valuable advice

And as firewall I prefer the commercial Agnitum Outpost Firewall Pro, or the free Comodo Internet Security (anti-virus and firewall, can be installed separately) instead of ZoneAlarm. I've heard quite a few bad stories about that one.
