Task Manager dialog box

[Yeah]

Hi,

Two problems:

1) When I press CTRL+ALT+DELETE, the task
manager dialog box appears, but only displays running
applications. The tabs that allow the user to view CPU
usage, network usage, processes, etc., are not present.

2) When I open Windows Explorer, the window
appears, goes blank, and causes my computer to run
EXTREMELY slow (e.g. to select an icon on my desktop, it
takes about 5-7 seconds). Curiously, if I work offline,
then Windows Explorer works fine.

1. Double click on the borde of the task manager window.
2. Shut down virus programs and try the same.
