How do you handle anti virus updates that occur during a PS session? For instance, if NOD32 provides a new signature update during a PowerShadow session it will disappear when I quit PS. Will NOD32 download the revised signature file a second time when I'm running is normal (un-shadowed) mode? I guess I could ask the same thing about any automatic downloads during shadowed sessions (Comodo f/w, Boclean). Thanks Jim PS, what about email that I want to keep that I download during a shadow session?
