error when booting up PC

May 27, 2009 at 5:28 PM

I am running XP.  Problem started a month or two ago. Each time I boot up my PC I get a screen that says:

EFS Assistant.exe - Common language runtime debugging services 

Application has generated an exception that could not be handled

Process id=0x74 (3444), Thread id=0xd78 (3448)

I hit OK to skip and PC works just fine.  My company help desk has not been able to resolve. They tried, but other problems popped up and we had to restore to earlier date.  Can you offer any suggestions as to what this is, and how to make it go away.
