Hello, I would great appreciate if someone could help me to resolve this error. I am constantly getting an error message "Runtime error . c:\windows\system32\SearchFilterHost.exe R6025 -pure virtual function call". Only OK is available to select but it never goes away. I can continue to use my computer by moving this error dialog to a side. Any idea what is causing this error. I think the error is coming from windows desktop serach. I am using windows xp professional. Thanks in advance.
