I have recently taken over as IT manager for a new start up company. I have been told to randomly check PC in our organisation for inappropriate content such as obscene material and pornography. Can anyone advise me as to what software I can use to do this? I want to be be able to identify if any of our users have viewed any of this content even if they use programs such as Evidence Eliminator to clean their PCs. Can their activity be tracked even after using these programs?
