Neil,

Thanks I hadn't found that KB article. I'll check the versions when I get to the office tomorrow. I had already verified that it was not the spyware virus.

>See http://support.microsoft.com/default.aspx?scid=kb;en-us;261004 Check the version number and dates, the SP update may have failed to update the file.

>Also check for a virus infection, regsvc.exe is also a process belonging to the Ace Spy advertising program by Retina-X Studios.
