Virtual Box - Host get a virus/trojan?

[mcrustk2]

Can programs running in a (sandbox) - XP running in virtual box affect the host OS?

What I mean is, say you download a freeware program off the net, Use virtual box to test it out but, the program contains a trojan/virus, can that trojan/virus effect the host OS?

the only way i could see it effecting the host, would be by network, if they are joined by network card (internally, if you get me)...

There's always a chance a virus author could have found/used an exploit to infect your main OS, but it's very very very (very) slim. Considering most people have probably never even heard of a virtual PC anyway, it's not worth their time.
