What is "winrxt.exe"?

I'm using Windows 2000 Professional. Lately, I noticed my PC's speed was crawling like a turtle. I activated Task Manager to see the processes going on. It shows CPU usage was constantly at 100%, even if no application program is running, although Memory usage is at normal level.  

I experimented removing some processes listed in the Processes Tab. There is this particular process, "winrxt.exe", in the Processes tab, I am not familiar which  uses much of the CPU. Removing it returns my PC to normal speed. Why is this so? What is "winrxt.exe"? Is this a virus?

This application resided in C:WINNT/SYSTEM32. Whenever I remove it from the Processes Tab in Task Manager, my PC returns to normal speed, meaning % CPU usage drops to less than 10%. However, when I reboot or turn on my PC for another session, the problem crops up again. I moved winrxt.exe from C:WINNT/SYSTEM32 and transfered it to D: drive and the problem is solved.  

I searched the web for "winrxt.exe" but there is always 0 returns or hits. It seems that no one is discussing "winrxt.exe". I am just curious about this applet because it has irritated me so much until I finally discovered it to be the cause of the snail-pace operation of my PC. That is why I am posting this query. Can anybody enlighten me about "winrxt.exe"?

Thank you.

Also use one of these to eliminate everything from your startup list. Then after doing that if the file doesn't load at startup then you just need to go through the startup list and find which item is the culprit.
