Locking computer????

[gohan89]

Hi,I am once again stuck with a grave problem.I am using Windows Vista Ultimate.
I have the BSNL 500 Night unlimited plan.I have solved the problem of automated connection.Here is what I do.
1)I turn on the modem.
2)Then using "BBscheduler",I give the timings,username,password,etc. and I schedule it.It then hides itself to the tray,but is still running.This is done at 12:30 am.
3)I run Bittorrent,where I place the torrent links ready to be downloaded when the BBscheduler reconnects at 2:10 am.The bittorrent also minimizes to tray and is running.
4)I just switch off the monitor and go to sleep.
Now the major problem is my brother,1 year younger.He saw the entire procedure.One night ,I find him surfing **** sites.I didnt tell him anything nor do i want to warn him.
I have thought of something to prevent him and dont know whther ir will work or not.Suppose,I folow the entire procedure above and just before turning off the monitor,I use the lock option in the strat menu and give a password to lock it.Then i switch off the monitor.
Now my queries are:
1)Will the BBscheduler be able to reconnect at 2:10 am?
2)Will Bittorent be able to download from torrent networks?
3)Will the modem respond to the BBscheduler?
Will these applications stop running?
Please do answer each of my queries.If this does not work,suggest any other method with step by step instructions,keeping vista in mind.please give as many replies possible urgently

just try once and see by setting the time nearby to current time.

You could just block porn sites using anti porn filter and setting password for the same. The functions available with Avira Premium Security Suite, don't know about others as i've been using this for like a decade.
