Task Manager fails to remain open

[Harold Ervin]

I am running XP Home Version on a desktop PC.
I right-click an empty area of the taskbar,
and then click Task Manager to start Task Manager.
Task Manager window opens briefly and then
closes after staying open less than one second.
What may be the cause of this ?

You have either the Klez or Yaha viruses.

I had the same problem on my PC at work, XP Prof, only
when I clicked the start menu and went to Documents, the
most recent Documents would only display for about half a
second. It did this for about 3 weeks, and then stopped.
Our IT manager couldn't figure out what caused it, and
he's pretty up on viruses.
