VMWare Fusion 4: Apps & browsing security concerns to host OS X

[RightMACatU]

Background:
Soon to have a 2012 MBA 13”/8/256 running OS X ML
Will install Windows 7 64-bit in VMWare Fusion 4
Will install torrent app in VM
Will browse Internet & torrent sites from within VM

Question:
Knowing that torrent sites & apps are gold mines for trouble, is there a way that “What happens in Fusion stays in Fusion” and not have an impact on the host OS?

Once I’m done with the torrent app, package the goods on a USB flash drive and Elvis leaves the building (close the VM).

PS: I’m open to using Parallels 7

Cheers!

Been doing some digging around and it should be ok. Any vulnerability introduced in the Win 7 VM will stay in it... unless I get something that is capable of 'handling' both OS... highly improbable

Close the VM when done and restart a fresh new one.
