Yes.

#1 reason... Virii that are scripted propegate on the users machine to where it will install itself , reboot the machine and continue to infect it. Without the CTRL ALT DEL buffer, it is hard to stop a virus in full effect.

No, as long as:
1. All computers are behind locked doors when the authorized user is not physically sitting in front of it (and the authorized user has the only key).
2. You implicitly trust ALL your users to not do anything stupid like open a virus-infected attachment.

Otherwise, you might just as well delete ALL user account and everybody the SAME generic user ID and password.

The issue is accountability. If you disable Ctrl-Alt-Del at logon (i.e. you are using auto-logon??), you don't know if the person actually using the computer is the same as the account that was used to auto-logon.

Ctrl-Alt-Del is in the firmaware and not your OS.

To fully disable it, you would need a custom BIOS.

For some versions of Windows, you can disable task manager from popping up when you use Ctrl-Alt-Del using system policies.
However, I believe that a double hit of the 3 finger salute will still reboot the PC.
