windows task manager shut down

[prashantbhavsar]

when i m trying to open windows task manager,
it opens only for a spur of a moment and shuts down automatically.
what's the cause of a problem ?
what should i do to fix this problem ?
and what one should do to fasten the PC besides installing anti-virus software  ?
please do needful.

You perform the Ctrl-Alt-Delete, and the Task Manager opens for just a moment, and then closes again?

I've looked around on the Internet, and found indications that this seems to happen due to virus activity on the computer, or malware activity on the computer.
