The good Doctor is a Microsoft employee. He is not a virus, a spyware or any other malware. He wears a white hat.

"Dr. Watson for Windows is a program error debugger that gathers information about your computer when an error (or user-mode fault) occurs with a program. Technical support groups can use the information that Dr. Watson obtains and logs to diagnose a program error. When an error is detected, Dr. Watson creates a text file (Drwtsn32.log) that can be delivered to support personnel by the method they prefer..."

Sometimes the Doctor will show up unexpectedly, then dissapear just as quickly and not show his face again for months and months.

I would not be concerned unless Dr. Watson starts to appear on a regular basis. If he does then you have serious issues with your Windows operating system. Often a reformat and complete re-install of Windows is needed.

Disabling Dr. Watson will only hide the symptoms, not provide a cure for the problem.

There is no such program called "yahoo msn".

Good luck.

I am suggesting you didn't get a clean download or you have virus's on your pc and the download got infected? Dr Watson is a debugging program, whether it comes with windows or your antivirus software, who cares its good stuff. Delete your copy of yahoo messanger, reboot your pc then try again. If you want an older version the links below. "Yahoo.msn"? or "Windows messanger live"?
