I'm trying out Shadow Defender on my notebook. OS : Windows Vista Home Premium Resident: Shadow Defender (all time in shadow mode with some folders excluded) Sandboxie (paid) Avira Security Suite Prevx (free) Browser: Firefox (all time sandboxed) So far, this combination looks good. As I share my notebook with my wife, I want to set up my notebook to be easy & user friendly, but also tight on security. I want Avira to update automatically, and able to save bookmarks in Firefox. I also want to be able to save files into My Document folders. Hence, what are the exclusion setting to be done? So far, I have exluded the following files: C:\Program Files\Avira\* C:\ProgramData\Avira\* C:\Program Files\Mozilla Firefox\* C:\Users\* Is there anything else to exclude? I read somewhere in Avira forum that the folder C:\Windows\Systems32\Drivers might also need to be excluded, but I don't feel good about this. Comments appreciated, thanks.
