Comodo EasyVPN (32-bit version)
P2P networks are appealing, but the "peers" you find there may be worse than the ones in the jury pool. With this freebie, you can create a secure, encrypted peer-to-peer network with anyone--not everyone--over the Web. Then you can chat and exchange files without fear of snoopers.
Note: This software comes in 32-bit and 64-bit versions. This is the 32-bit version. If your 64-bit PC is running 64-bit XP or 64-bit Vista, please download the 64-bit version instead.
