Location of this file is in the same 2 places for me as it is for David. Since it's not in system32, I don't think it's harmful, but I can't say for sure. I know nothing about this file besides the info on this page.
AcGenral.dll is the Windows Compatibility DLL
as mentioned it is Compatability. I have it in use with Illustrator 8 running on WinXP SP3. It is a "shim". I guess Illustrator 8 is not quite WinXP-ready.
