FileMap by BB - Find secret files added to your system.
If your firewall fails allowing files to get secretly installed, or you find extras in the windows and system folders mysteriously growing over time, compare before and after file lists, to show which do not belong. FileMap by BB easily discloses differences by comparison.
It is a FREE security utility that does not need to run in the background. The drag and drop installation adds no Spyware or AdWare, and is totally non-intrusive.
