Some suspicious computer users believe that, while they are away, others are accessing their computer, running unauthorized software or malware. Other wary users may find it interesting seeing what other people have done on a particular computer, what programs they may have run, what documents were viewed, and when the computer was booted and shut down. If a computer was infected by malware, it may often be of great interest to see what was being run on the computer at the time of infestation, and even identify the malware and its payload.
