How to remove padlock

[Justrahul]

I am very frustrated with this problem and if anyone can tell me how to remove the padlock that is always present on a blue background on the computer screen, it would be great. I will appreciate all help that is offered to me. Thank you

Well, can you please post a pic or a screenshot of your problem? It would be hard to guess what would be the exact problem to diagnose. Are you using any antivirus programs? Also if you can post reports of HijackThis or Combofix here, we would be able to solve the problem.

If you are on the screen then first try to highlight your HD icon and then hold command key and click "I" key to get info. In the resulting window, click on the padlock at bottom right. Enter your password if asked. Close this window, and you should be alright.

How to stop users from locking screen

Steps already taken
--------------------
1) vi /etc/dt/app-defaults/C/Dtstyle
--> remove the "Screen" control icon fr Style Mgr

2) vi /etc/dt/config/C/sys.resources

dtsession*extension.saverTimeout: 0
dtsession*extension.lockTimeout: 0

3) DELETE /usr/dt/bin/dtscreen
chmod 400 /usr/dt/bin/dtstyle

4) For every users found locking screen subsequently,
DELETE $HOME/.dt

However, SAME users still able to find ways of locking screen.

Also attached a "ps -ef" of one of those who locked screen before I used root password to unlock the screen & delete ".dt" from its home-dir.
