Run untrusted files with no risk of infection.

amazing program, sorry if this is wrong section or people know about this one already.

basically it's a separate hard drive area from your os, that you can run things in. however this wouldn't prevent a keylogger stealing your password if you logged into that account with an infected program. but it would prevent a virus from spreading itself on your computer. it's great for testing things, or scanning files you don't trust. amazing for sketchy keygen's on torrents too :nuts:

hope it helps save a few headaches for someone.

 

I use this, but I use it inside a vmware workstation - can't be safer
