This little application runs silently and allows you to protect your computer from hackers, and sneaky people who just want to steal your info. I once caught my friend trying to use my computer...he suceeded getting through the Vista password prompt, well this device works even btter. It allows you to have 2 passwords, and remember, 2 different from your curent vista password, and never give thes eout either. It will flash twice once you start it up to verify it works. Then it will run silently, lurking...Right-click the Notify Icon and you can select from options. It does exactly what Vista Log-In Does, except it also monitors in real-time what a person is doing. Fail to many-times, and it won't let you log-in, or even try for the selected length of time. It also whatches for rapid mouse movement, or the "Cntrl+Alt+delete" uttons. It will cancel taskmanager, which means it will not allow anyone, even if they, to even stop the process. If it detects to much mouse movement over a period of time, or to many random key presses, it will auto-lock, for the selected time-out. Haxcker's beware!
