For the past week I have been reading up on the various threads on this board regarding a number of programs. I am still confused as to exactly how these programs are used in the context of security and/or recovery as many of their features seem to be overlapping. Could I challenge the experts here to explain with a few clear statements (and cutting through all the marketing spin on the product sites) the prime usage for the following products to help me better understand. 1. Imaging Software like ATI 2. FirstDefense_ISR 3. Programs like Powershadow or ShadowUser 4. Sandboxie From what I read these programs all have some features in common but are often used together. EricAlbert characterizes Imaging Software a must and FirstDefense_ISR a luxury (which I gather he very much likes). Seems to me that I can live without ATI using only the luxury product just purchased if I "avoid" a hardware crash. Other programs mentioned here are Returnil and RollbackX (not sure if they belong in 2 or 3 above). I would have thought that RollbackX is similar to FirstDefense_ISR but appster corrected me by stating FDISR and RB are similar in purpose, but not in their concept.
