E.g. I install Ubuntu as my main system without anything else but VirtualBox and maybe some programs that need to be installed to run VirtualBox.Then I install within VirtualBox Windows 7 (because I need to run a custom program from my comapny that is exclusively for Win) and maybe another Ubuntu or some other Linux distro for my daily stuff (browsing the web, testing some untrusted linux apps, downloading stuff via torrents etc.).The question is, am I safe when I run apps/browser within my VirtualBox or do some viruses/malware/spyware exist that can access my main Ubuntu system from Windows 7 or the other linux distro that runs inside VirtualBox?
Is it safe to run everything from VirtualBox?

It depends on what you mean by safe.VirtualBox is a way to abstract the hardware through full virtualization (it is a type 2 hypervisor: https://en.wikipedia.org/wiki/Hypervisor). So it does provide you a degree of protection from any virus running in the guest OS. The extent to which you are safe is likely how paranoid you may be, but your host operating system is likely to be unaffected by any virus you may catch in the guest.In short, you're pretty safe.
