Hi, folks: I have been using DeepFreeze standard for just over 2 weeks. I do like it and could not help thinking that using virtulization technology to protect your pc system is'nt a bad approach at all. There are other good sanboxes apps on the market such as ShadowUser, DefenseWall, GeSWall, Sanboxie and BufferZone. Can you share your experience of these apps with Forum viewers? Thanks.
