interesting- never heard of it before. i am traveling internationally for a couple months and will be using a lot of wifi connections for trading and such. i am set up well at home- never an issue. but.... obviously, trading from a hotel/whatever, i have less control of the network i'm sharing with ???? so, is this (sandboxie) the best defence to add to my existing laptop firewall/anti-virus (avast)? if not, i'm open to suggestions. i'm lugging enough shit already, so it has to be software-based. thanks.
