Comodo EasyVPN (64-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 64-bit version, which is for 64-bit PCs running a 64-bit OS. If your PC is running a different supported OS, please download the 32-bit version instead.
