Vista - F-Secure Anti-Virus and Windows Offender

Why has F-Secure Anti-virus program have a built in Anti Spyware ( Which is
designed for Windows Vista) when Windows Vista already has Windows
Offender?....Does this not slow down the system when running two Anti-Spyware
programs at once?...

It disables the Windows Defender. - > you can have a look if you try to run
the defender from the startmenu it will tell you that it is disabled.

BTW : I do not recommend the F-secure thing. It is buggy as hell, and if it
finds a virus you cannot click on the "delete" or "Quarantene" Buttons,
because with Aero running, the buttons are on the bottom of the window, are
not clickable, are only half-way to see and the window can't be maximized...

Also it bogs down your system and eats too much of memory.
I have uninstalled this as soon as I could and returned to avast home, which
is in my opinion the best and the latest versions are full vista-compatible
( it already saved me from lots of viruses in winmail.)
