Avast 6 64-bit?

I know avast! 6 can be installed on a 64-bit OS. My question is does avast! 6 actually run as a 64-bit program? On http://www.avast.com/free-antivirus-download#tab3 it says that 64-bit support is a “New” feature. I installed avast! 6 on my Windows 7 SP1 64-bit but according to Windows Task Manager avast! still shows up with a ‘*32’ tag on it.

Thanks!

It isn’t a native 64bit application and it doesn’t need to be, where necessary on a 64bit OS it would install the relevant drivers, etc.
