Answer 3

Do you mean the dialog box named Windows Security and buttons with options such as Task Manager, Lock Computer.., Shut Down, Log Off, etc

If this is the case then there isn't a virus problem, but somehow your Login/Logoff settings got changed. Do this to bring back the Task Manager:

>> Click on Start>Control Panel>User Accounts. (Classic view in Control Panel)

>> Click on Change the way users log on or off...

>> Click on Use the Welcome Screen.

>> Click on Apply Options and then close the User Accounts window.

>> Now try pressing Ctrl+Alt+Del.

Note that this will only work in the conditions I've mentioned above. If the dialog box is something different it might not work.

Hope your problem gets solved.
